沥青混合料体积参数通用图的应用研究

为了使沥青混合料体积参数在设计和施工质量控制中得到进一步应用，将体积参数分为直接参数和间接参数．通过对体积参数之间内在关系进行数学推导变形，将沥青混合料设计中通常使用的体积参数与沥青含量之间复杂的非线性关系转变成使用体积参数之间的简单线性关系，适用于不同的沥青混合料设计与评价．在此基础上，进行了体积参数通用图的实际应用研究．理论分析和实际应用结果表明，它可以从体积组成角度去解释压实机理与间接参数之间的关系，从而指导沥青混合料设计与施工控制，值得推广．

Application of the Universal Volumetric Chart of Hot - Mix Asphalt Mixture

In order to make further application in hot- mix Asphalt design and quality control,the volumetric parameters were divided into the direct and indirect parameters. Through mathematical manipulation of the inherent relation between the volumetric parameters,the complicated non - linear relation between the volumetric parameters and asphalt content was replaced by the simple linear relation of volumetric parameters in asphalt mixture design, and it is suitable for different kinds of asphalt mixture design and quality control. On this basis, practical application of the universal volumetric chart was carried out. Theory analyses and the result of practical application show that it can explain the relation of compaction mechanism and the indirect volumetric parameter from the angle of the volume structure , and so it can guide the mixture design and quality control and is worth popularizing.
