寒区道路排水性沥青稳定碎石性能的综合研究
发布时间:2018-10-09 19:48
【摘要】:根据北方的气候特点,设计了3种级配的开级配沥青混合料,并对其性能进行了透水性、水稳定性、力学性能和低温稳定性的检验。利用层次分析法对3种级配混合料性能进行综合评价,认为ATPB-25更适合作为寒区沥青路面排水基层。这种综合评价材料的路用性能的方法可以为其他结构材料的选择提供借鉴。
[Abstract]:According to the climatic characteristics of northern China, three kinds of graded open graded asphalt mixtures were designed, and their properties were tested for water permeability, water stability, mechanical properties and low temperature stability. Based on the comprehensive evaluation of the performance of three gradation mixtures by analytic hierarchy process (AHP), it is considered that ATPB-25 is more suitable for the drainage base of asphalt pavement in cold region. This method can be used for reference in the selection of other structural materials.
