As Marshall test does not apply to the mix-design for open-graded friction course, drainage test and Cantabria abrasion test were adopted to determine the mix ratio based on the expected air void of mixture.
本研究在严格控制目标空隙率的基础上 ,采用流淌试验和磨耗试验相结合的方法确定了大空隙沥青混合料的配比 ,同时对大空隙沥青混合料的高温稳定性 ,水稳定性以及透水性进行了研究。
The binder run off test and cantabro abrasion test are the best methods to decide the drainage asphalt capacity.
利用结合料流淌试验和Cantabro磨耗试验来确定排水性沥青混合料最佳沥青用量是一种较好的方法。
