在综合分析各种沥 混合料设计系统,其 中的沥青结合料规范 青的试验结果的基础上,提出了常规沥青的针人度 (PerformanceGradedasphaltbinderspecification, 等级和SUPERPAVE的PG高温等级间的关系。 简称PG分级)作为SUPERPAVE的主要内容之一 1 沥青样品 引起了极大关注。目前该规范已经在美国的多数州得 到了广泛的应用。由于...
This paper documents an accelerated pavement testing (APT) study to compare hot-mix asphalt mixtures constructed with PG 76-22 (PMA) and PG 76-22 (ARB). This APT study represents the final stage of the implementation of a new PG 76-22 (ARB) specification. 展开 ...
(1). The result of the SHRP work on asphalt resulted in a Superpave Performance-Graded 16 Binder Specification (2) that allows agencies to specify asphalt binders that resist rutting and 17 low-temperature cracking. 18 The PG rating is intended to provide test methods that can grade asphalt ...
