Authors: Kolomeichenko A V , Sharifullin S N , Logachev V N , Izmalkov A A 
Published: August 2019

AbstractThe article presents the results of studies of the effect of flux components on the adhesive strength, porosity and oil absorption of coatings obtained by supersonic arc metallization (EM) using aerosol fluxing (AF) deposited on 45G2 steel with a speed v = 400-410 m / s. Due to the use of AF in EM, the adhesion strength of electrometallization coatings (EM coatings) increases. The highest value of adhesive strength is 66 MPa. Porosity due to the use of AF decreases by 1.5 - 1.6 times, in comparison with EM coatings without AF. At the same time, the oil absorption of EM coatings using AF decreases 1.6–1.7 times. It is advisable to use EM coatings with AF when restoring worn-out parts for various purpose equipment, as well as for eliminating defects at the production stage.

Authors: Shmelev G N , Sabitov L S , Galimullin I A , Khaidarov L I , Antonov A S 
Published: August 2019

Abstract
Operation of stands with canopies is possible under different landscape conditions, including conditions in areas with a slope or in areas with various obstacles that change the profile of the wind flow and, accordingly, affect the distribution of wind pressure acting on the surface of the canopy. Determination of the actual wind loads on the stands with a canopy is an important task due to the lack of appropriate schemes in the SP 20.13330.2016 “Loads and impacts”. The relevance of this problem is associated with the complexity of tests in specialized wind tunnels, as well as with the rapid development of computational fluid dynamics. In this regard, a numerical study of the aerodynamics of these structures was made in the software package ANSYS Fluent for the analysis of flows of liquids and gases. The article presents a comparison of the results with the schemes of wind pressure for awnings from SP 20.13330.2016 “Loads and effects” and Eurocode “Wind effects”. The obtained results were used for verification of similar calculation technologies and specialized software systems, addition of regulatory documents and for “adjustment” of newly commissioned wind tunnels (in order to optimize and improve the efficiency of tests).

Published: August 2019

Abstract
Strength enhancement in cold asphalt emulsion mixtures (CAEMs) is continuing and reliant on the rate at which curing proceeds. The initial life strength is low and exhibits a challenge in asphalt pavement design. The solution can be made through subjecting the specimens to accelerate laboratory curing for achieving practical conditions. Kind of mineral filler, asphalt emulsion type, curing time and temperature, and moisture content is five major factors in early age advancement of designing properties. By studying these factors, there is a requisite to build up a curing system that simulates as reasonably as actual conceivable conditions of pavement during early life. This study examines the requirement for speeded curing strength that is reasonable by concentrate distinctive curing protocols and the impact on mechanical properties of cold asphalt emulsion mixes. The experimental configuration is cautiously chosen so as to the curing conditions incorporate protocols which are trailed by various literary works and furthermore circumstances that are required for simulating different times and temperatures. The examination incorporates both cement kiln dust (CKD) and limestone mineral filler (LMF) as a filler to be utilized in the blends. One of the findings of this study is, the inclusion of (CKD) leads to strong results better than those of lime stone mineral filler mixes.

Abstract
Accelerate the drainage process and consolidate saturated clay soils is important to achieve stability of the construction. Vertical drains, with a suitable grid and depth, the result of shortening the path of water flow inside the soil and soil consolidation rate increases from several years to several months. Sombar earth dam, a case study, in Gholaman village in North Khorasan province, Iran, is used to provide agricultural and drinking water in the area. The recent paper shows a comparison between the results of Sombar dam stability with vertical drains of two different materials using the Mohr-Coulomb model with the aid of GeoStudio 2012 computer software. The drains materials are sand and geotextile and the investigated parameters are permeability ratio (ky/kx), drains geometry and time of the dam construction. The results are presented as ratios, settlement ratio (SSAND/SGEOTEX) and safety factor ratio (FSSAND/FSGEOTEXT). The results revealed that there are clear increases in the consolidation settlement ratio, but, slightly increase in safety factors ratio using sand drains comparing to the geotextile. The ky/kx has a clear effect on settlement and factor of safety in sand drains.

Authors: Al-Mansoori T , Hussein J , Aziz H 
Published: August 2019

Abstract
In this paper, a comprehensive state-of-the-art study regarding the mechanism and enhancement of self-repair in asphalt pavement is presented. The review starts with defining the self-repair phenomenon as a natural property in asphalt materials that is associated with other properties such as the viscoelastic response. The difference between self-repair and the viscoelastic response is also presented. In addition, the factors influencing the self-repair mechanism (positively and negatively) are investigated. However, some of these factors remain vague and need to be investigated further. Furthermore, two enhancing self-repair processes, which are extrinsic technologies such as induction heating and encapsulated rejuvenators, are presented as alternative preventive maintenance applied to asphalt pavement. In conclusion, the self-repair could be achieved in an economic way in countries with hot climates, such as Iraq where temperature plays a significant positive role in enhancing the asphalt repair if enough rest period is provided, without the need to other extrinsic technologies to be applied.

Abstract
The current study investigates the influence of the current density (CD) and electrodes gap (EG) on the removal of reactive red 120 dye (RR-120) from drinking water using electrocoagulation (EC) process. The influence of CD was studied by treating the dyed water at three different CDs (2, 4 and 6 mA/cm2). While the influence of EG was investigated at three EGs (5, 10, and 15 mm). The Results obtained showed that increasing the CD enhanced the removal of the dye. However, increasing the EG significantly decreased the dye removal efficiency. It was found that dye removal increased from 87% to 98%, as the CD increased from 2 to 6 mA/cm2, respectively. While increasing the EG from 5 to 15 mm decreased the dye removal from 96% to 80%, respectively.

Authors: Al- Fawzy A M , Al- Mohammed F M 
Published: August 2019

Abstract
The present study aimed to investigate the effect of using the conventional (rectangular) shape of gabion weir in dissipating the energy of flow. For that a series of laboratory tests (25 experiments and 194 test runs) were conducted on the gabion weir by using of a laboratory flume of 12 m long by a cross section of 0.3 m width, and 0.5 m height to test five different lengths of the weir, (40 cm, 60 cm, 80 cm, 100 cm, and 120 cm), with five respective monosized samples of natural quarry gravel with diameters (9.5-14) mm, (14-19) mm, (19-25) mm, (25-37.5) mm, and (37.5-50) mm. The tests were conducted for a range of discharge (0.7-15.0) l/s. Dimensionless analysis was used to analyze the data by using Buckingham Pi-Theorem to find the relation between the difference in energy of gabion ends and the unit discharge. Beside, a comparison discharge was chosen to find the relation between the difference in energy of gabion ends and the other variables. Results of experiments showed that the difference in energy increase by increasing both the unit discharge and the length of the gabion weir and decrease by increasing the equivalent diameter of the gravel sample.

Published: August 2019

Abstract
In this research, Nano-metakaolin was used to investigate the achievable prospects to enhance asphalt mixture properties. The aim of this study was to evaluate the effect of adding Nano-Metakaolin on the properties of asphalt mix and comparing it with the local and international requirements, besides identifying the optimum percent of NMK to be incorporated in the hot mix asphalt. As a modifier to the bitumen several percentages of Nano-Metakaolin was used i.e. 1, 2, 4, 8, 16 and 20% by weight of bitumen. Modified asphalt binders were subjected to physical and conventional tests which were penetration, kinematic viscosity, softening point, and ductility. From these tests, optimum Nano-Metakaolin was 16%. After obtaining the optimum Nano-Metakaolin, two sets of asphalt concrete mixtures were prepared, the first was with the pure asphalt (control mixture) and the second was with the optimum Nano-Metakaolin i.e. 16% (modified mixes). The control and modified mixtures have been evaluated based on experimental tests, such as Marshall Stability (MS), Marshall flow, Marshall stiffness, Indirect Tensile Strength (ITS) and Index of Retained Strength (IRS). The results for these tests indicated an improvement in the mechanical proprieties i.e. increased Marshall Stability, Indirect Tensile Strength (ITS), and index of retained strength. As a final result, the use of (16%) Nano-metakaolin by weight of asphalt enhanced asphalt concrete properties and produce durable mixtures for highway construction.
Performance of piled raft foundation supported by either connected or unconnected piles
Authors: Alhassani Athraa M J , Aljorany Ala Nasir 
Published: August 2019

Abstract
Piled raft is commonly used as foundation for high rise buildings. The design concept of piled raft foundation is to minimize the number of piles, and to utilize the entire bearing capacity. High axial stresses are therefore, concentrated at the region of connection between the piles and raft. Recently, an alternative technique is proposed to disconnect the piles from the raft in a so called unconnected piled raft foundation UCPR, in which a compacted soil layer (cushion) beneath the raft, is usually introduced. The piles of the new system are considered as reinforcement members for the subsoil. In the current study, the behavior of both connected and unconnected piled rafts systems has been studied experimentally. The effects of different factors, such as; the piles number and configuration, on the load settlement behaviour and pile load sharing are also investigated. The results indicate that when unconnected piles are used, the total settlement of the piled raft system is significantly reduced, and the pile load sharing considerably decrease, e.g., for piled raft with nine piles the total settlement has decreased by 35.6% and pile load sharing has decreased by 20.9%.

Published: August 2019

Abstract
An experimental investigation of PVC-concrete columns is presented to assess the efficiency of using PVC tube for enhancing strength and ductility of PVC-concrete columns. Study was conducted to assess provided PVC casing confinement mechanism efficiency for enhancing strength and ductility of considered PVC- concrete columns. To investigate the composite mechanism and confining mechanism of the PVC tube, fabricated specimens are tested under uniaxial compression loading in two modes of load application; composite mode and confining mode. The results showed that the composite mode columns exhibit more strength improving than those of confining mode. The upgrading rate in sustained loading resistance of composite mode columns varied from 2.25 to 1.56, while it was 2.07 to 1.55 for confining mode columns. The same comparison is entirely reversed in scope of ductility, where confining mode columns exhibited more axial and lateral deformations than the corresponding composite mode columns. The results are normalized in term of radial stress (fr
) and concrete compressive strength (f’
e
), determined enhanced confined concrete strength (f’
