摘要
粗集料的强度和颗粒形状特性对排水性沥青混合料的性能影响较大,而且在高温和重载条件下更为显著。通过大量的室内试验分析了粗集料压碎值和针片状含量对排水性沥青混合料性能的影响。测试结果表明,压碎值高、针片状颗粒含量多的粗集料会造成排水性沥青混合料的排水功能、抗飞散性能、抗水损坏性能的下降。
Strength and particle shape properties of coarse aggregate have great impact on porous asphalt mixture performance which is more significant at high temperature and heavy load conditions. Through a large number of laboratory tests, analysis on the influence of porous asphalt mixture performance for coarse aggregate crushing value and flakiness content. Test results show that, coarse aggregate with high crushing value and particle flakiness content can cause performance degradation of porous asphalt mixture, such as drainage function, anti-scattering properties, and resistance to water damage.
