抗滑级配沥青混合料体积参数及性能对比试验

Mentioned parameters and performance contrast test of anti-slide gradations of asphalt mixture

选用两种抗滑类型沥青混合料:AC-13K(又称改进型AK-13A),Superpave-13,按照马歇尔沥青混合料设计方法设计得出AC-13K型混合料的最佳级配和最佳沥青含量(为5.2%);按照Superpave法成型试件得到Superpave-13的最佳级配和最佳沥青含量(5.1%),对两种沥青混合料分别在已确定的级配形式和最佳沥青含量的情况下制备马歇尔试件,测定其主要参数,并进行了抗水损害试验和车辙试验,以了解两种沥青混合料的抗车辙性能和抗水损害性能。

This paper used two kinds of anti-slide type asphalt mixture： AC-13 K（ also called improved type AK-13 A） , Superpave-13, according to Marshall asphalt mixture design method to design that the optimum level and the optimum asphalt content（5.2% ） of AC-13K mixture, according to the Superpave method molding to design the optimum gradation and the optimum asphalt content（5.1% ） of Superpave-13, to the two kinds of asphalt mixture respectively prepared Marshall specimen in the conditions of having been identified gradation form and the optimum asphalt content, determined its main parameters, and made the water damage resistance and rutting test, in order to understand the rutting resistance and water damage resistance of the two kinds of asphalt mixture.
