Asphalt mixtures are subjected to short-term aging during the production, placement, and compaction processes. Proper evaluation of asphalt pavement performance relies on the accurate characterization of asphalt mixtures during the design stage. In this study, three different loose asphalt mixtures often used in Qatar were evaluated to develop a laboratory short-term aging procedure. Sample mixtures 1 and 3 were collected from a construction site, while mixture 2 was obtained from an asphalt plant. Virgin aggregates and binders were also collected to reproduce the mixtures in the laboratory. Laboratory-produced mixtures were conditioned at 135 °C using various time durations. The mechanical properties of laboratory-produced mixtures were compared to those of mixtures produced on site. The results of the mechanical and binder testing demonstrated that the proper short-term aging protocol for asphalt mixtures often used in road construction in the State of Qatar would involve heating asphalt mixtures for 4 h at 135 °C before laboratory compaction.

Abstract, in case of the construction of road in soft soil, it is necessary toconsider the use of materials around the road construction site, and not touse selected material which is imported from outside the road constructionsite. Thus, aim to overcome the difficulties of using selected materials, namely the difficulty to obtain the materials, the price of expensivematerials , the freight of material that could takes a long time period, highcost, and the use of materials that tend to be environmentally unfriendly. Itis very necessary to learn about the use of nonstandard additive materials, taken to the road construction site, but with the use of geotextilereinforcement. The research method used is a full scale method in the formof trial embankment, so that the performance of the road can be observedfor a long period of time due to the traffic and soil settlement. The resultsobtained is settlement that occur on the road from the combination ofordinary embankment material and local material, most frequently occuredin a larger percentage of ordinary embankment than the local material. While the visual value is relevant to the settlement in which a largerpercentage of ordinary embankment results in a better visual value, due tothe quality of the ordinary embankment material is better than the localmaterial.

This research aims to identify the risk variables that ever occurred while executing of road construction project. In addition, it is to identify how significant and how big the influence of risk variables to the articulation of project execution processes of a road construction project, based on questionnaire that distributed to 30 questionnaires who are project managers and site managers on contractors of road construction project.  From the research data, there were identified 14 risk variables with 84 risk sub-variables on execution of road construction project. Those 14 risk variables were natural, social, politic, economic, law, occupational safety and health, managerial, technical, cultural, logistic, condition around construction site, design and technology, labor, and contractual variables. From the data analysis by using SPSS version 16, obtained there were 14 risk sub-variables which became the most influential sub-variables (indicators) to the road construction project. All sub-variables on the questionnaire are valid and reliable. The results of this research is expected to be considered for all parties involved in the construction project to pay more attention to risk variables during the execution of road construction project.

Security Incidents

With the rapid development of the economy in China and the speeding up of urbanization, urban roads and highways in China continue to increase. However, due to some of the characteristics of road construction, long duration, high fluidity, large volume of work and complex process, there exist many security problems during the period of construction, which determines that security management is unoptimistic on construction site. This paper makes a comprehensive research over the achievements of domestic and foreign experts and analyzes the causes of the security incidents in domestic road construction, so as to further clarify that the deep reasons for the security incidents in management. Based on this, the author advances the corresponding security management measures. With comprehensive evaluation methods applied on road construction site, the security situation can be predicted and prevented whenever and wherever possible.

Construction Works

Poland, which biological diversity stands out in comparison with the rest of Europe, became one of the biggest road construction site during the last few years. A development of a road network almost always involves disturbance of biogically sensitive and protected areas. As those areas cover about one third of the whole country it is virtually impossible to avoid conflicts concerning biological protection. For those reasons, steps to be taken to limit to a minimum the incidence of the construction works on the biological environment constitute an integral part of each investment. The costs of protecting unspoiled environment represent up to 30% of the total costs of investments. The effectiveness of planned actions must consequently justify spending the considerable funds involved. Monitoring of the results of solutions used allows both verification of their usefulness and identification possible errors so that they may be avoided in the future. Number of actions which have been undertaken in Poland to minimalize the incidence of roads on unspoiled environment, in particular as regards the number of fauna passes, to preserve the ecological continuity, place Poland among most advanced European countries.
