Authors: Gáspár László , Karsai Katalin
Published: January 2025

The paper presents the main steps of modifying the Hungarian road policy to include also cement concrete pavements after several decades of its exclusion. The results of preliminary laboratory tests are shown. A test section on the road 7538 was built in 1999 which consisted of three cement concrete subsections of various techniques and an asphalt pavement control subsection. Their performance has been monitored since then. The time data series of several condition parameters and the results of visual condition survey permitted to evaluate and to compare with each other their performances. Besides, a rigid, a semi-rigid and a composite test section were constructed on a Hungarian main road in 2003. These sections are also monitored. A third cement concrete pavement trial section on main road 4 was built in 2004 with an asphalt pavement control section. Its initial condition parameters were also evaluated. Using the performance results of these sections, a new Hungarian road policy was set up including the basic principle of pavement type selection.
Concrete Overlay Design of Flexible Pavement Using the NCHRP 1-37A Design Guide —A Case Study—
Authors: Darter Michael I. , Titus-Glover Leslie , Mallela Jagannath
Published: January 2025

A pavement evaluation and concrete overlay design was completed for a 10- mile section of flexible pavement on Interstate 35 of the Kansas Turnpike. A records review, visual condition survey, rutting measurements, and testing with a falling weight deflectometer (FWD) was conducted. Coring was also performed to establish the condition of underlying hot mixed asphalt (HMA) layers. The results were used to evaluate the conditions of the in-place pavement and to design rehabilitation alternatives. The evaluation indicated that the existing flexible pavement had deteriorated to a state that requires rehabilitation. A requirement of the design was to maintain the existing surface elevation, thus, the design portland cement concrete (PCC) overlay thickness would be milled off from the existing 330-mm (13-in) HMA layer thickness. Several alternative concrete overlays were designed and evaluated using the new Mechanistic-Empirical Pavement Design Guide (ME PDG) from NCHRP 1-37A. A variety of informative sensitivity results are shown including an optimized concrete overlay design for the I-35 project and comparison is made with the 1993 AASHTO procedure. In addition, designs are also presented for lower traffic conditions to illustrate its impact on design. The results demonstrate the practical use, reasonableness, and benefits of the new M-E PDG for PCC overlay design.
Evaluation of Formulae in PCA Design Approach for Ultra- Thin Whitetopping over Composite Pavement Section under Accelerated Loading
Authors: Newbolds Scott A. , Galal Khaled A. , Olek Jan , Nantung Tommy
Published: January 2025

Ultra-thin whitetopping (UTW) is a popular pavement rehabilitation technique that involves the placement of a thin layer of portland cement concrete (PCC) over a distressed hot mixture asphalt (HMA) pavement. The new pavement is essentially a thin bonded concrete overlay. Thus, its composite performance depends on the stiffness of the underlying pavement layers. One objective of this project is to develop models that can be used for the mechanistic design of UTW pavements. Additionally, UTW performance models will be developed. To accomplish this task, a UTW pavement test section was constructed in the Indiana Department of Transportation – Purdue University Accelerated Pavement Testing facility. The pavement section consisted of a UTW overlay of an existing composite pavement section (thin HMA layer over a PCC layer). The performance of the UTW overlay was monitored using destructive and non-destructive methods, including measurements of strain, strength, and pavement stiffness. PCA design guidelines were investigated to assess their applicability to cases of UTW placed over composite pavements. Preliminary results indicate that the equations may be able to be used if the concept of an equivalent thickness is employed. Further, the effective radius of relative stiffness calculated from falling weight deflectometer testing of in-situ pavements may be able to be modified to account for the proposed UTW overlay and input into the design equations.

Published: January 2025

This paper is focused on evaluating the performance of several concrete mixes of high-performance concrete (HPC) pavement using different techniques such as laboratory testing, warping and curling monitoring and falling weight deflectometer testing. A research plan was developed to accomplish two principal objectives: First, to determine the maturity function of the newly placed concrete, and second, to monitor dynamic and environmental response of concrete slabs in each of three test sections. Each test section was approximately 1,000 feet long. Five hundred feet of each test section were cured using a spray-on membrane, while the other five hundred feet were cured using wet burlap. Three Concrete mixes using different types and sizes of coarse aggregate and granulated blast furnace slag were incorporated into this project. Two slabs in each test section were instrumented with thermocouple sticks at the center and outside corners.

Published: January 2025

Porous concrete pavements were applied on a trial basis at three points on prefectural roads in Fukui, Japan. The objective was to verify their durability and serviceability as well as their behavior in snow and cold regions. Investigations were made continuously to check their serviceability and durability with lasting performance. The major parameters investigated included pavement smoothness, skid resistance, rutting and difference in elevation at the joint. Such parameters as permeability and low noise level were unique to porous concrete pavements. This paper describes the results of a follow-up survey during the three-year period since the commencement of service. The surface properties, in-situ permeability and noise level of the porous concrete pavements remained nearly unchanged from the conditions upon completion although deterioration was observed in some sections. Thus, porous concrete pavements were determined to be fully applicable to snow and cold regions.

Faced with shorter and shorter windows for reconstructing deteriorating pavements in urban areas, transportation agencies are continually searching for new and innovative techniques for rapid pavement construction. The California Department of Transportation (Caltrans) is one such agency, often limited to 7-hour nighttime construction windows in the Los Angeles and other metropolitan areas. One innovation recently examined by Caltrans is precast concrete pavement. A 76 m (248 ft) section of precast, prestressed concrete pavement was constructed on Interstate 10 in El Monte, California, adding 8 m (27 ft) of traffic lanes and 3 m (10 ft) of shoulder to the existing pavement. The majority of the work was completed at night when lane closures were permitted on Interstate 10. The precast panels were pretensioned during fabrication and then post-tensioned in place to enhance the performance of the pavement. The successful completion of this project provided Caltrans yet another tool for rapid pavement construction in one of the busiest urban areas in the world.
Framework for Design and Construction of Long-Life Concrete Pavements
Authors: Tayabji Shiraz
Published: January 2025

In the past, concrete pavements were routinely designed and constructed to provide low-maintenance service life of 20 to 25 years. In fact, the majority of the U.S. interstate and the primary system were designed on the basis of the 20 to 25 year initial service life. Experience has shown that pavements in high volume traffic corridors need to be designed and constructed to provide longer service life because of the difficulties in performing effective repair and rehabilitation activities along these high volume highway corridors. In addition, the public is no longer tolerant of frequent extended lane closures to perform repair activities. It is becoming an established practice in the U.S. to require that concrete pavements provide low-maintenance service life of 40 plus years. PCC pavements can meet this specific requirement if proper considerations are incorporated in the design and good construction practices, including use of sound concrete making materials, are followed. This paper provides an overview of current U.S. practices and efforts at optimizing pavement design features and construction practices to minimize early age failures and provide long-term low-maintenance service in excess of 40 plus years. The paper also provides a framework for ensuring that the critical design and construction features that impact long-term service are recognized and accounted for. The design and construction features discussed include features that improve slab cracking and deflection responses, features that minimize maintenance operations, and construction features that assure long-life pavement.
Impact of Slab Curling on Backcalculation Analysis
Authors: Zaghloul Sameh , Marukic Ivana , Vitillo Nick
Published: January 2025

Falling Weight Deflectometer (FWD) testing is performed on rigid pavements to assess the in-situ structural capacity of the pavement system, to evaluate the load transfer efficiency across transverse joints/cracks and to identify joints with high possibility of voids underneath the slabs. Tests are performed at different times of the day (day and night), different seasons and different temperature conditions. This data is used in the analysis to identify the network needs and prioritize these needs considering budget and performance constraints. One key issue in this process is that FWD data collected under different environmental conditions is compared and decisions are made based on the comparison results. Therefore, an effort should be made to minimize the impact of the difference in environmental conditions during FWD testing on the final analysis results. Decisions, such as repair joints having low load transfer efficiency, underseal joints with voids, or repair slabs with low structural capacity, are made based on analysis of results of FWD testing that was performed under different temperature and moisture conditions. A classic example of temperature impact on Maintenance & Rehabilitation (M&R) decision is corner curling, which may be identified mistakenly as potential void. Undersealing the joint in this case may cause more harm to the slab. Another classic example is the artificial high load transfer observed when FWD tests are performed at high ambient temperatures (>80oF). Therefore, it is essential to make sure that the difference in temperature and moisture conditions do not have a significant impact on the FWD analysis results to avoid making inaccurate decisions at the network and project levels. This paper presents an effort to account for the impact of daily temperature variation on FWD analysis results for rigid pavements. The work presented in this paper is a part of a large-scale research study sponsored by the New Jersey Department of Transportation (NJDOT) to study the seasonal variation in pavement properties and its impact on pavement response and performance.

Published: January 2025

This case study presents an innovative fast-track reconstruction approach applied to a heavily trafficked LLPRS project on Interstate-15 (I-15) in southern California. A 4.5-km stretch of badly damaged concrete truck lanes, two in each direction, was rebuilt in only two 210-hour (about 9 days) one-roadbed continuous closures, using counter-flow traffic and around-the-clock operations as accelerated construction, an undertaking estimated to take 12 months using traditional nighttime closures. This post-construction case study validated pre-construction estimates of productivity and traffic delay, which closely matched performance data measured during construction. The I-15 Devore project provided a unique opportunity to validate, fine-tune, and enhance highway analysis tools for future LLPRS projects. The use of CA4PRS schedule analysis and other traffic models presented in this study facilitates teambuilding amongst engineers involved in the design, construction, and traffic phases to mutually arrive at an optimal solution.
Load Transfer through Aggregate Interlock: Crack Width, Aggregate Type and Performance
Authors: Strauss P. J. , Perrie B. D. , Du Plessis L. , Rossmann D.
Published: January 2025

It is well known that performance of plain jointed concrete pavements depends on aggregate interlock to transfer load from the one slab to the next. In order to quantify the relative contribution of crack width and the strength of the aggregate to the long-term performance of a plain jointed pavement, experimental sections of road were built using different aggregates types. These sections were subsequently loaded to failure using the Heavy Vehicle Simulator (HVS). Some typical sections of interstate-type highways, which had been under traffic for between ten and twenty years were also investigated using FWD testing and determination of changes in crack width with changes in temperature. Detailed asbuilt information including concrete mix characteristics was available for all these sections. This paper discusses the prediction of crack width using the RILEM model which predicts early age shrinkage. The model was modified to include the effects of aggregate type, environmental conditions and age. The change in load transfer at the joints and cracks, as indicated by relative vertical movement under dynamic loading as a result of temperature variation and humidity, is reported on. It was found that a change in load transfer occurred under increased loading and that this could be related to the crushing characteristics of the coarse aggregate. This paper presents the final outcome of the study in terms of theoretically based equations that were adjusted using regression techniques to fit the field experience. These equations have now been incorporated into a mechanisticallybased design method for concrete pavements, cncPave.
Remaining Service Life of Concrete Pavements
Authors: Flom Ewa R. , Darter Michael I.
Published: January 2025

A proactive approach to protecting or maximizing the investment of concrete pavements requires periodic assessment of the pavement condition to determine deficiencies and predict deterioration patterns. Pavement management strategies must be employed at an optimal time in order to attain the most cost effective maintenance and rehabilitation solutions for the structure. Determining the remaining pavement service life is critical for making better decisions about preservation treatments, rehabilitation, or reconstruction. This paper discusses three key approaches developed for determining concrete pavement remaining service life (RSL) and presents case studies demonstrating the use of each method. The three methods include an empirical based procedure, a new approach based on survival curves, and a comprehensive mechanistic based procedure using the new National Cooperative Highway Research Program (NCHRP) Project 1-37A analysis methodology.
Statistical Challenges presented by the SPS-2 Experiment and Data

Published: January 2025

The challenges presented by the Specific Pavement Studies-2 (SPS-2) experiment and data for statistical analyses are presented in this paper. Experiment-related issues included (i) wide variation in traffic levels and ages among the fourteen test sites; and (ii) unbalanced distribution of test sites among climatic zones and subgrade types. The challenges presented by the data included (i) outlier issues, (ii) quantification of performance, and (iii) the lack of measurable distresses due to the “young” age of test sections. In this paper the importance of selecting appropriate data analysis methods for obtaining reliable results is illustrated. Though most of the methods that were applied for the analysis are wellestablished, the choice of the methods (magnitude- versus frequency-based) was driven by the extent and occurrence of distresses. Based on the current status of the data, frequency-based methods such as Linear Discriminant Analysis (LDA) and Binary Logistic Regression (BLR) lend themselves well to explaining trends associated with occurrence of cracking; whereas a magnitude based method like analysis of variance (ANOVA) is appropriate for evaluating joint faulting and change in IRI.
The High Performance of the Concrete at the Shuttle Landing Facility
Authors: Weiss William R. , Bryan Bob
Published: January 2025

The Shuttle Landing Facility (SLF) located at the Kennedy Space Center (KSC), FL, is the prime landing location for orbiters returning from space. The facility was constructed in the mid-1970’s to address the need of having a landing facility near the Space Shuttle launch site. The primary pavements were constructed of portland cement concrete (PCC) and have performed very well up to this point, in part due to an on-going aggressive maintenance approach. Stringent operational requirements make this runway unique in several ways, and maintaining the runway surface to a high standard is critical. Condition measurements have been conducted on a biennial basis and provide an update for the SLF staff on areas in need of immediate repair, as well as tracking the overall deterioration patterns and planning for future maintenance efforts. The SLF is a tremendous example of how to maintain a pavement network in excellent condition for as long as possible.
VENCON 2.0: a Fast and Reliable Design Tool for Concrete Road Pavements (jointed and continuously reinforced applications)
Authors: Leest Adrian J. , Stet Marc J.A. , Frénay Jerome W.
Published: January 2025

In the Netherlands, concrete pavements varying from low volume country roads to dual carriage motorways, are designed with the ‘VENCON 1.0’ program. This program has been developed in the eighties and was originally meant for the design of jointed concrete pavements. An enquiry amongst the users revealed the need for an update towards the Windows operating system but also a technical update became necessary. The update also gave an opportunity to reconsider the design models, to incorporate CRCP design and ‘standardise’ input data such as the latest practical measurement data from axle loads and tyre spectra of vehicles as well as temperature gradients in the concrete pavement. The classical Westergaard formulae for thickness calculation of concrete layers were extended with Van Cauwelaert's closed form solutions to cater for bound base layers. The ‘Delft University tensile member model’ is used to design the reinforcement and to predict the cracking pattern of the continuously reinforced concrete pavement. This model is validated with in-situ measurements of two CRCP roads. The program distinguishes three user levels (junior, senior, expert). VENCON 2.0 was developed under CROW’s responsibility and came onto the market in early 2005. It is used to design both jointed plain concrete pavement (JPCP) and continuously reinforced concrete pavements (CRCP). This paper provides an outline of the calculation process and the main improvements to the program.
Monitoring of Strength Development in Portland Cement Concrete With High Fly-Ash Content at the FAA’s National Airport Pavement Test Facility
Authors: Garg Navneet , Ricalde Lia
Published: January 2025

Construction Cycle 2 (CC2) at the FAA’s National Airport Pavement Test Facility (NAPTF) included construction of three concrete test items MRC, MRG, and MRS on three different support conditions (crushed-stone subbase, slab on grade, and econocrete stabilized subbase). All three test items were constructed on a CBR 7-8 subgrade. The existing econocrete subbase (P-306) from CC1 test item MRS was used for CC2 MRS. Concrete was placed in the test items using a concrete pump into fully formed 15 ft. (4.57 m) by 15 ft. (4.57 m) slabs. Test results are presented and discussed in this paper. Test results include concrete placement details (slump, air content, concrete temperature), compressive strengths, flexural strengths, elastic modulus from free-free resonance tests on concrete beams and cylinders, portable seismic pavement analyzer (PSPA) tests, and strength results from sawed beams and cored cylinders taken from untrafficked test slabs. Concrete specimens included both laboratory cured and field cured specimens. PSPA tests were performed on the test item slabs at the age of one day and on regular intervals after that, coinciding with the laboratory testing of beams and cylinders. The test results showed good correlation between elastic modulus (from free-free resonance and PSPA tests) and strength values (compressive and flexural strengths) and demonstrated the application potential of a testing device such as PSPA for assessing the early-age strength of concrete.
Unique Aspects of the Design and Construction of the Bristol Motor Speedway CRC Pavement
Authors: Swift Stephen , Zollinger D. , Bhasin A. , Masad E. , Mukhopadhyay Anol
Published: January 2025

The reconstruction of the Bristol Motor Speedway (BMS) track surface presented some unique challenges to the placement of a continuously reinforced concrete (CRC) pavement. Due to the steep embankments of the radial sections, it was not feasible to use a traditional type of bond breaker to isolate the CRC from the subbase layer and so it was determined to bond the CRC to the base and eliminate the interlayer from the pavement section. Reflection cracking from the subbase was a concern and as a counter measure special crack control precautions were taken to insure the uniformity of the crack pattern using early aged crack control which required additional modifications to the sawing equipment to adopt it to the geometry of the track. The design of the steel was also configured to account for the bonded condition and the geometry of the track.
Behavior of Concrete Mixtures in Ultra-Thin Whitetopping Composite Pavements
Authors: Bordelon Amanda , Roesler Jeffrey R.
Published: January 2025

Ultra-thin whitetopping (UTW) is an alternative pavement rehabilitation option to asphalt concrete overlays. UTW is typically a concrete overlay less than 5 inches thick on an existing distressed asphalt pavement. A research project was recently finished to refine the current UTW design methods and develop new recommendations for improved UTW performance. As part of this project, a laboratory study investigated various concrete mixture effects on UTW performance. Seven mixture designs containing various w/cm ratios, cementitious content, discrete fiber-reinforcement content, and two coarse aggregate types were studied. A composite beam test (concrete placed on an existing asphalt beam) was developed to predict the composite section behavior in the laboratory. For this small-scale 2D testing, the results were not as dramatic as expected between the different concrete mixtures. However, the fiber-reinforcement, which increased the total fracture energy of concrete, demonstrated improvement in the load carrying capacity after initial cracking. The concrete mixture design alone was not the sole indicator of the UTW performance. Higher strength concrete mixtures can fracture just as rapidly as normal strength concrete if the UTW exhibits debonding. It is recommended that structural fibers be added to the concrete to extend the performance life of the rehabilitated pavement, especially in the presence of existing asphalt cracks and potential interface debonding.
Composite Computational Model for Portland Cememt Concrete Pavement
Authors: Tian Bo , Niu Kai-min
Published: January 2025

It is well known that there are two models in pavement calculation, one is Winkler model and the other is multi-layered elastic model. In this paper, a new bi-parameter computational model is presented for analyzing layered base and subgrade in the Portland cement concrete pavement. In the new model the subgrade is represented by a group of the springs with k-vaule, and subbase/base are modeled by elastic multi-layer there has several elastic layers on Winkler foundation. However either Winkler model or Boussinesq and Burmister model only use one material parameter, the modulus of reaction k or elastic modulus E. So the new model has the merit of the two classical models. Finally result of the new model is compared with the enhanced k-value method in PCA, FAA, etc.

Published: January 2025

Fibrous concrete has a history in pavements. In the ’80-s fibrous concrete became popular thanks to options such as reduced pavement thickness and increased joint distances. Unfortunately, not all promises were kept and the fibrous concrete ‘silently’ disappeared from the pavement construction scene. However, in industrial floor construction research continued and new concrete mixes containing different types of new steel fibres were developed. Design guidelines were developed to harmonize structural design rules. The track record in industrial floors with steel fibres has become sound. Over the years, the new fibrous concrete returned to the pavements. Several successful projects were constructed and at the instigation of the developers of these mixes a working group for the investigation of fibrous concrete was formed by the Dutch Technology Platform for Transport, Infrastructure and Public Space (CROW). A team of steel fibre producers,  concrete experts, researchers and contractors had the task to evaluate the performance of recently constructed pavements. The study may lead to recommended practices for the application of fibrous concrete in the Netherlands. The paper elaborates on the fibrous mixes currently in use and presents the results of recently constructed projects.

Published: January 2025

Acne is a condition of sebaceous follicle disruption caused by keratinization disorders (small keratosis), accompanied by the presence of comedones, papules, pustules, and nodules. Starfruit (Averrhoa bilimbi L.) harbors compounds exhibiting antibacterial properties against Propionibacterium acnes, making it a promising candidate for developing an anti-acne emulgel product. The starfruit was extracted via maceration using 70% ethanol solvent over 3x24 hours. Test samples of starfruit extract were prepared at concentrations E1 (10%), E2 (15%), and E3 (20%), while emulgel formulations of the extract were formulated as F1 (10%), F2 (15%), and F3 (20%). Physical evaluations included organoleptic, adhesion, spreadability, homogeneity, pH, emulgel type assessments, and antibacterial tests measuring inhibition zones. Inhibition zone data were analyzed using ANOVA statistics. The method used to observe antibacterial activity in the emulgel formulations employed the good diffusion method by measuring inhibition zone diameters around the holes. The results of antibacterial activity testing of starfruit extract emulgel formulations against Propionibacterium acnes sequentially in F1, F2, F3, K+, K- were 11.96 ± 0.38 mm (strong), 13.84 ± 0.50 mm (strong), 15.03 ± 0.56 mm (strong), 17.64 ± 0.69 mm (strong), and 0 ± 0.00 mm (no antibacterial activity). The evaluation results of the physical quality of starfruit extract emulgel formulations indicated that all three formulas exhibited good physical quality. Based on the study findings, F3 demonstrated superior inhibitory efficacy among the emulgel formulations.
Church and Parish Life in the DPR/LPR in the Period 2014–2022: On the Materials of the Ukrainian Orthodox Church of the Moscow Patriarchate
Authors: Komar Iana V. , Prigarin Alexandr A. 
Published: January 2025

In the article, the authors analyzed the circumstances surrounding the Ukrainian Orthodox Church of the Moscow Patriarchate between the years 2014 and 2022. The following issues were considered: the evolution of the position of the UOC MP regarding the assessment of the conflict; the theological and material problems associated with this position and the internal context in which parishes and priests in DPR and LPR operated. The lower chronological frame is due to the beginning of the military conflict in eastern Ukraine in 2014, and the upper one is due to February 2022, which marked the beginning of a special operation in Ukraine and the entry of the DPR and LPR into the Russian Federation. The range of sources is represented by materials in the public sphere, including official documents of the UOC MP, news reports and statements of the UOC MP published on the relevant representative websites, sermons and interviews, comments, blog and forum entries, the legal framework of the DPR/LPR. From 2014 to 2022 the Ukrainian Orthodox Church of the Moscow Patriarchate adopted a stance of neutrality towards the parties to the conflict, officially claiming to be outside the conflict. The available evidence indicates, however, that the clergy members who found themselves on the territory of the DPR/LPR collaborated with the authorities of the republics despite the official neutrality of the UOC MP. This collaboration was not motivated by negative sentiments or financial gain, but took the form of cooperation aimed at establishing a new shared space and fostering new meanings. Thus, religion was regarded as a crucial state-forming pillar, with the objective of social organization.
Anthropology of Art: Questions of Theory
Authors: Koshaev Vladimir B. , Missonova Liudmila I. 
Published: January 2025

The article presents preliminary interdisciplinary criteria for understanding the subject field of art in the interaction between anthropology and art studies. It is important to highlight the methodological approach adopted in the comprehensive analysis of artistic content in relation to different geographical regions. It is crucial that scholars from diverse scientific disciplines engage in the theoretical comprehension of the Russian cultural field. The authors posit that the distinctive and particular content of the anthropology of art resides in the circumstances of culture, which may be understood in three dimensions: sacral/ethno-national-religious, socio-organisational, and nature-production. These dimensions may be conceived as parts of the “matrix of being,” which is essential for scientific comprehension of the object and subjects of the discussed scientific direction. There is currently no agreed scientific or practical substantiation for the anthropological nature of art in its ethnic understanding. The systematic classification of factors of production, social and religious modes of life within the cultural context of diverse peoples, in conjunction with historical periodization, enables the introduction of a typological dimension that is characteristic of ethnic art. Accordingly, the anthropological/ethnocultural aspect of art should be examined in the context of the causal relations between the material and spiritual purpose of the ‘thing’ (human-function-form). It is important to engage in interdisciplinary dialogue on this topic, but it is essential to reach a consensus on the categories of subject matter and the conditions for their formulation.
