表面层沥青混合料路用性能试验研究

经过总结高速公路沥青混合料配合比设计的经验，结合SUPERPAVE的设计思想在现行规范级配的基础上，提出了一种嵌挤密实型的级配沥青混合料，通过马歇尔试验确定沥青混合料的最佳油石比，并对最佳油石比下的沥青混合料进行了高温稳定性和水稳性检验，通过比较得出S形级配的可行性。

The experiment research of surface layer pitch mixing function in the road

The paper passes the summary superhighway pitch mixing matching ratio design experience,joins together the SUPERPAVE design thought based on current norm class the foundation,puts forward a kind of solid pitch mixing.Passing Marshall tests the certain pitch mixs with the best oil ratio,it tests the heat stability and water steady,putting out the possibility of the type class of S.
