| 摘 要： | 大空隙沥青混合料是指空隙率在15%以上的间断沥青混合料，其具有优良的使用性能，但常规的马曷尔试验已不适用来进行配合比设计。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。表征本研究提出的方法是一种简单易行的方法，与密级配沥青混凝土相比，大空隙沥青混合料具有高的高温稳定性，水稳定性和透水性。

| Abstract: | Open-graded friction course is a gap-graded one with 15% air void, which has excellent performance. 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. Meanwhile, with the study on its stability and water permeability, it is shown that this method is not complicated and easy to use. Open-graded friction course is better than dense-graded mix for its good stability and water permeability. |
