Ma Yao Highway Broken Cement Concrete Pavement Asphalt Concrete Surface Engineering Technology Package Research

In this paper, Ma Yao Yulin city, Shaanxi Province Highway damaged asphalt concrete surface layer reconstruction projects relying on the test section, combined with practical engineering situation, for the broken concrete paved asphalt concrete surface layer of difficulty, through disease investigation, design, construction process, test detection research and engineering practice, forming a broken Cement Concrete Pavement Asphalt Concrete Surface engineering technology package.Ma Yao Highway is Shenfu mining coal transportation road, access for many years, the road a long time in heavy loads, road damage serious need of repair and renovation in order to ensure the safety and smooth flow of traffic. In order to explore the broken cement Concrete Pavement Asphalt Concrete Surface sets of technologies, in the engineering design, the reference to the advanced experiences of other places, combined with other factors such as engineering practice to conduct a multi-program design. Determined through practice asphalt layer structure, with the ratio of key technologies such as construction technology. Reflective cracking overlay structure is the focus of design considerations. In order to reduce reflective cracking in engineering applied to water-proof anti-cracking layer, geotextile and other measuresMain aspects of the construction process of the construction with the ratio of the surface layer of construction, STRATA stress-absorbing layer construction and other aspects of the study, especially for areas with hot summers and rain in Yulin conditions, do to reduce water damage and increase the high temperature stability considerations, but also In order to project the quality of the raw materials, surface smoothness, degree of compaction of asphalt concrete and other indicators have done a higher demand.Ma Yao highway damaged Cement Concrete Pavement Asphalt Concrete Surface Engineering Test Section has achieved good results. The entire test section design engineering, construction technology for the future roads and the like Ma Yao heavy traffic conditions, broken concrete rehabilitation programs provide a valid reference point.
