A Place of Sustainable Development in Contemporary Urban Concepts
Authors: Mazur-Belzyt Katarzyna 
Published: September 2019

Abstract
The concept of sustainable development has promoted around the world for years by taking action to implement it on a global scale. Hence, as a development paradigm, it appears in many strategic documents at every planning level. The main goal of the research is to determine whether and to what extent the idea of sustainable development manifests itself in the contemporary urban concepts. The analysis covered publications, events and selected urban projects. As the beginning of the time frame, the 1960s were adopted, which together with the 1970s are the background to the changes that led to the crystallization of the idea of sustainable development. This is a period of decline and criticism of the idea of modernism, the crisis of cities, as well as the beginnings of the trend of postmodernism. The following years - the 80s, 90s and the beginnings of the 21st century - is a gradual development of the concept: a compact city, a green city, an intelligent city, as well as searching for ways to implement sustainable development in cities. The analysis of the contemporary concepts of shaping cities has shown a lack of consistent, uniform planning and urban planning criteria for sustainable development. However, this does not necessarily mean the faults of the idea itself, but the advantage of an individual approach to each city and the possibility of its flexible implementation. The conducted analysis also showed that particular contemporary concepts are based on similar assumptions, or even are opposed to each other. None of them offers the perfect city. Individual ideas of urban development can be implemented separately or creatively combined with each other. Although none of the ideas of shaping cities is fully complete and universal, it is important to treat the city as one organism, and seeking for its sustainability, consistently use selected planning tools, adapting ideas to the context and scale of the city. Further search for the right direction of urban development is a task that in a given time perspective may lead to an improvement in the spatial, social, economic and environmental situation, and consequently to a higher quality of life for the residents.
Analysis of the Real Estate Market Dynamics as the Effect of Changes in the Road Infrastructure - Case Study in Poland
Authors: Mika Monika 
Published: September 2019

Abstract
The paper is of analytical and research nature. The scope of the research includes a case study of the real estate market as a result of the rebuilding of a part of the road infrastructure. The purpose of the work is to determine the impact of the development of the communication system on the activity of the real estate market in two communes of the Żywiec district on the example of the section of the S1 expressway. Each type of investment carried out on the market has a positive or negative impact on the environment. The construction and development of the communication system are often a stimulant of the region because in most cases they increase its economic level. As a result of this kind of investment activities of the commune, there are changes on the local real estate markets, related to the spatial development of the region, affecting the standard of living of the population or the level of attractiveness and competitiveness of the region. These changes should also be visible in the level of transaction prices on the local real estate market. Therefore, the analysis of the number of transactions and the level of transaction prices of non-built-up agricultural and forest real estates were undertaken. The research period concerned the time from 2008 to 2015. The research area was made up of two communes in Southern Poland, located in the Malopolska voivodship. A section of the S1 road is located in these communes, the reconstruction of which is an important element of the research. Analyzes carried out allowed to answer the question of whether the development of the communication system in the analyzed communes affected the average prices per 1m2 of undeveloped land. Is there a relationship between the time the transaction is made and the price? Did the year 2011 (as the date of initiation of investments) cause a systematic increase or decrease in the number of transactions concluded? On the basis of the statistical analyzes carried out, it was found in the examined case that there was no linear relationship between the time variable (T) and the price variable (P). This means that these variables are not correlated. The various values of the coefficient of variation calculated for the data of both communes indicate a large dispersion of transaction prices in the examined period. Basic statistics such as: the correlation coefficient, the coefficient of variation, standard time and price deviation, max and min values, median, kurtosis, as well as skewness were examined for the tested sample.

Abstract
Thermal protection regulations for the buildings change. Currently, the construction sector aims to minimize the energy consumption. Energy Performance Directives have introduced the standard of “Nearly Zero Energy Building” (NZEB). After 2021, the design of NZEB buildings will be mandatory. The parameters of NZEB buildings in Poland are very difficult to meet and concern the thermal insulation of housing structures and the non-renewable ratio of the original PE. In the article, the Authors reviewed traditional and modern thermal insulation materials that will allow meeting the thermal insulation requirements for the external walls of NZEB buildings. Another problem raised by the authors is the insulation of historical buildings. The aim of the article is to compare the parameters and prices of the thermal insulation materials such as foamed polystyrene with innovative materials such as aerogels.
Assessment of the road and railway infrastructure and means of public transport by the aspect of the survey in the selected area of Poland
Authors: Iwanowicz Damian , Kempa Jan 
Published: September 2019

Abstract
The current socio-economic conditions of some developed and developing countries are not favorable for the development of the public mass transport services. Most of the residents of large and medium-sized cities, but also smaller towns, use their own passenger car on mandatory trips. This phenomenon perfectly reflects the constantly growing of motorization index in such countries. The consequence of this is, of course, the decreasing number of passengers carried by means of public mass transport, in particular operating outside of large urbanized areas. This causes and unfortunately will cause not only further problems of automotive congestion on the transport networks of urban areas, reduction of the road safety level, but also adverse environmental effects in the form of pollution. The authors of the article analyzed the results of transport surveys, which were carried out in recent years among the public transport passengers. The surveys concerned the assessments and postulates and expectations of passengers. The research was carried out in one of the typical in terms of socio-economic conditions of Polish voivodships (a country dynamically developing in the passenger transport sector, in terms of both mobility, as well as the quantitative and qualitative status of transport means and transport infrastructure). The voivodship subjected to such analysis was the Kuyavian-Pomeranian Voivodship, located in the central part of Poland. The respondents were asked to speak on topics related to, among others, transport infrastructure, means of transport, access to services of public transport systems, comfort and safety of traveling. The analysis also included assessments and postulates related to tariff systems, travel information systems, and transport integration systems - functioning in the voivodship. The results of the research were analyzed by the rail passenger transport and bus passenger transport as part of the voivodship public transport system. In the majority of cases, passengers’ assessments were not satisfactory. The most frequently issued evaluations fluctuated only around the average (on a scale from 1 to 10). The authors have thoroughly analyzed the results of the transport survey, confronting the results obtained and trying to find out their causes depending on the characteristics of the area under analysis.

Published: September 2019

Abstract
The results of concrete tests on cements with mineral additives indicate that, despite better tightness and higher strength, there are problems with frost resistance of non-aerated concretes, even under conditions of moderate exposure to frost. In order to minimize problems with obtaining frost-resistant concrete, an attempt was made to create air-entraining cement. In this paper are presented frost resistance of concrete with air-entraining cement. The researches were carried for concretes made of multicomponent Portland, metallurgical and multi-component cements additionally differentiated by the type of air-entraining admixture (synthetic and natural) and the method of cement preparation (cement mixed together, common ground cement). There were tested internal frost resistance of concrete and a salt frost scaling of concrete.
Minimising the material consumption in bionic and geometric structural forms
Authors: Nowak Anna 
Published: September 2019

Abstract
Interdisciplinary design in an important process is influencing the shaping of the architecture. In contemporary architectural design, the integration of the form and load-bearing structure is becoming more and more important. The integrated design process enables verification and selection of solutions that are more advantageous in relation to the given criteria. As a result, it is also possible to search for the model solutions in an attempt to optimize the architectural-construction as an important element of the interdisciplinary design process. Synergic methods of architectural design, enabling the creation of more effective systems, are of particular significance. The combination of the architectural and structural analyses is increasingly visible, especially in the research projects, where the form of the object is created in a synergic way, taking into account other parameters such as the properties of the materials used. The search for possibilities of shaping optimal and sustainable structures led to the creation of analogies to the living organisms, as exemplified by the bionic architecture. Architects are interested in methods of surface discretization, which can influence not only the aesthetic perception of the object, but also the material efficiency of the load-bearing structure. As a result of such a design, the search for synergistic solutions that meet both aesthetic and endurance criteria is pursued. The minimization of the material consumption by means of interdisciplinary analyses is part of the sustainable architecture trend, which respects the environment and its resources. The article presents the model research, based on the analysis of the structural forms with homeomorphic assumptions, which corresponds to homologous transformations among structures of common evolutionary origin. In analytical research on the selected models, computer-aided design methods were used to minimize the material consumption.

Published: September 2019

Abstract
Life-cycle assessment (LCA) is a systematic methodology used to assess the potential environmental impacts associated with all the stages of a product or system. Generally, the LCA is performed for all stages of the evaluated product; nevertheless, based on the goal and scope of an LCA study, several phases may be considered, whereas others may be excluded. In this study, an LCA was conducted to evaluate the potential environmental benefits related to the use of recycled concrete aggregates (RCA) as a partial replacement of natural aggregates in the production of Warm Mix Asphalt (WMA). In order to estimate the potential environmental impacts associated with the use of these alternative resources in the construction and rehabilitation of road pavements in Barranquilla, Colombia, primary data were collected in some companies in the region. The SimaPro 8.4.0 software was used for modelling the processes analyzed in the case study and all the life cycle inputs and outputs related to the functional unit were characterized during life cycle impact assessment (LCIA) phase into potential impacts according to the impact assessment methodology TRACI v.2.1. The pavement life cycle phases and processes included within the system boundaries were the following: (1) extraction and processing of natural and recycled aggregates and production of asphalt binder, (2) transportation of materials, and (3) production of the asphalt mixtures. Three percentages of RCA replacements were analyzed:15, 30 and 45%. By comparing both asphalt mixtures with different RCA replacements levels, it was shown that RCA use implies an increase in the optimal asphalt content, which in turn, originates higher potential environmental impacts than those stemming from conventional mixtures.
Design and Research of the Bending Test Set-up for the Longitudinal Joints in Segmental Tunnel Linings
Authors: Zhang Jinfeng , Zhao Ming 
Published: September 2019

Abstract
As a weak link of the segmental lining ring in the shield tunnel, joints are main reasons for large deformation which further lead to various diseases during the tunnel construction and operation. These diseases, including water leakage, dislocation, joint opening, concrete crack etc., are detrimental to the safety and durability of the tunnel structure. In order to better understand the mechanical behaviour of joints, especially the longitudinal joints, much more attention have been paid to carry out corresponding experimental study. However, the design of the test-up is rarely covered in a lot of literature, which is also a critical factor for a successful experiment. In this paper, a test-up used for experimental study of the longitudinal joints in segmental tunnel rings was designed and executed in detail. The test device met both the test site requirements of the Building Structure Laboratory of Tongji University and the bearing capacity requirements under the maximum test load. After calculating the maximum horizontal and vertical test loads, the design of the test device system was completed. The setup included a short column, transverse and longitudinal loading beams, hinge supports, segment sleeves, supporting platforms and pillars. The test device can realize bidirectional loading and meet the requirement of large deformation of the test members during the test, which can provide a reference for the design of similar or even more sophisticated segmental joint test devices in the future.
Laboratory Performance Evaluation of Co-Polymer Based Dust Suppressant Mixed with Poorly Sand
Authors: Wu Ziyan , Ho Chun-Hsing , Huang Junxin 
Published: September 2019

Abstract
Fugitive dust, generated along unpaved roads or uncovered construction sites, defined as a type of atmospheric matter (PM), is considered as a major source of air pollution in metropolitan areas. Fugitive dust can potentially cause respiratory illness and lung damage for humans, and even lead to premature death in sensitive individuals. Aiming to reduce the fugitive dust emission on unpaved roads, scientists did various lab experiences to analyse the performance of different types of dust suppressants mixed with different soils. In our previous papers, we evaluated the co-polymer-based dust suppressant (CPS) mixed with loamy sand (soils are from Sedona, Arizona) and silty clay (SP-SC) (soils are from Flagstaff, Arizona). The objective of this paper is to analyse the efficiency of fugitive dust reduction and present the quantitative laboratory evaluation of CPS mixed with poorly sand (SP). The soils were sampled from Page, Arizona. Soil classification is based on United Soil Classification System (USCS). Four concentrations of CPS (0%, 1%, 3%, and 5% by weight) were diluted and mixed with soil samples to prepared soil specimens. A series of laboratory experiences were performed on the soil specimens including moisture retention test, surface strength test, dynamic rolling test, and scanning electron microscopy (SEM) imaging. The laboratory results show that the higher the concentration of CPS is, the better CPS performs, and CPS with 5% concentration by weight controls the dust emissions better as compared with the other three concentrations, provided the results from the moisture retention rate, surface strength, dynamic rolling resistance, and interlock/cohesion effect in SEM images are promising.

Published: September 2019

Abstract
Flam Valley is a bauxite residue Tailings Management Facility (TMF) valley pond, operating since 1971, located in Romania, just a few meters away from the Danube Delta protected area. Since then, it has been serving Alum Tulcea alumina producing plant through the different stages of its development. Conceived as a frontal tailings dam, Flam Valley is located in a nonpermanent torrential stream in a very sensitive environmental protected area. Up to 2006 tailings slurry with 15-20% solids were pumped by pipeline in the TMF, in accordance with the old technology. After the EU directives enforcement in 2005 the plant had to stop all activity until the whole process was upgraded, consequently the TMF was upgraded with the structural frontal dam being reinforced, water diversions constructed, some areas of the residual storage area were ecologically restored and the deposition became a dry stacking process by tailing placement, thus transforming it into a new TMF and avoiding the consequences that would have derived from the relocation of the TMF. The presented aspects are aimed at generally portraying the evolution, incidents, the tailing dam behavior and prospects of capacity enlargement for Flam Valley TMF.

Published: September 2019

Abstract
Sustainable development is a basic principle of modern world society. One of important aspects of sustainable development is care of natural resources, To achieve this goal it is obligatory to use within building materials those from recycling. In terms of road engineering it refers to all reclaimed materials from pavement construction, however, one of the most valuable of them is reclaimed asphalt pavement (RAP). Its use in production of new hot mix asphalt (HMA) is promoted due to environmental issues but it also causes concerns among road administrators. Aged bitumen, being an ingredient of RAP, poses a threat to new HMA, decreasing its cracking resistance regardless of its source. Aged bitumen is more brittle than the` virgin one, thus high RAP content may lead to the same sort of problems within HMA. To enable high RAP content in HMA there are additives (rejuvenators) introduced onto aged bitumen (RAP) to restore its characteristics. Choice between applied rejuvenators is crucial task along with its content in accordance to amount of aged bitumen. The aim of the paper is to pinpoint differences between effects obtained after use of different rejuvenators on mix consisting of 100% RAP. The effect was shown on void content determination and Marshall stability test. Results showed significant differences between 4 rejuvenators of different types, making some of them more effective in comparison to others. Tests confirmed possibility of further investigation on 100% RAP mixes made of confirmed-quality RAP.

Authors: Profeanu Virgil 
Published: September 2019

Abstract
The paper presents an effective urban solution of update for the General Urban Plan (GUP) of Bucharest in order to reduce air pollution. The proposal presented is based on the good urban design planning practice offered by other cities that manage to preserve the air pollution level below an established limit. Firstly, the paper includes a literature review I carried out in order to study the latest scientific research papers related to the subject and the examples of good practice. Furthermore, the paper highlights the present situation in Bucharest generated by the high levels of air pollution and the need to reduce the toxic emissions. Romania has committed through Directive 2016/2284 of the European Parliament and of the Council to reduce the national emissions of certain pollutants. In addition, the proposal of update for GUP was developed according to the present national targets and to the specificity of the city, existing green space, tree density, small size surfaces. If the urban solution presented is applied through the General Urban Plan, the air quality in Bucharest will be considerably improved and the positive effects will not wait to appear in different perspectives, such as: inhabitants’ health condition, urban aesthetic, efficient use of the allocated budget for the improving air quality in the European capital. In order to successfully implement the urban solution, the present research has to be completed by an arboretum study in Bucharest. The topic of the paper is characterized by multidisciplinarity as it takes into consideration research information from Urban Design and Ecology.
