基于骨架密实理论的矿料级配设计方法研究

Study on the Design Method of Aggregates Grading Based on Dense Framework Theory

现行的《沥青路面施工技术规范(JTG F40-2004)》中给出的矿料级配范围过宽,给实际工程的配合比设计带来较大困难。以杭州湾大桥南接线路面工程为背景,通过对国内设计方法的研究和室内的对比试验,提出了简便易行的矿料级配设计方法。

The aggregates grading bound given in actual technical specification for construction of highway asphalt pavements is too big so as to bring difficulty for practical project asphalt mixtures design. Based on south connection pavements of Hangzhou bay bridge , this paper investigates the actual design methods, then brings out indoor parallel test, puts forward a simple and convenient aggregates grading design method.
