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。
This paper has designed mix design of three kinds opens grades ATPB,and has examined its road performance according to the weather characteristics of the north,through experiment. The water permeability,the water stability,the anti-cracking at low temperature and mechanics performance of ATPB have been studied by experiment. Using the analytic hierarchy process to comprehensive assess three kinds of gradation mixture performance,and concluded that ATPB-25 is more suitable as permeable base in cold area. The other structural material choice also can take this method to comprehensive evaluation materials performance.
