摘要
采用3%、4%以及5%3个不同的设计空隙率进行Sup-20混合料的设计,并对这3种混合料的高温、低温、抗水损害、疲劳性能进行室内试验。试验结果显示在形成较为良好级配的基础上,混合料的设计空隙率对沥青混合料的性能有一定的影响,4%设计空隙率设计的混合料可以获得优良的高温性能,而5%设计空隙率设计的混合料则具有略好的低温、水稳定性以及疲劳性能,3%设计空隙率设计的混合料各种性能都不占据优势。
This paper used three different design porosity of 3%, 4% and 5% for the design of Sup-20 mixture. It also had indoor test of high temperature, low temperature, anti water damage and fatigue performance for three kinds of mixture. The test results showed that the design porosity of mixture had a certain influence on the asphalt mixture performance based on better gradation etc.
