沥青热再生混合料最大理论密度计算公式

Maximum Theoretical Density in Hot-mix Recycling for Asphalt Mixture

针对厂拌沥青热再生混合料配合比设计中传统计算公式使用性差,且规范尚未对此作出明确规定这一情况,通过对旧沥青混合料的分析,参照传统公式,采用理论计算分析结果和实测结果进行比较,在此基础上推导出适用于计算热再生混合料最大理论密度的计算公式。

According to the limitied utility for the traditional formula in the design of grading envelop during the hot-mix recycling for asphalt mixture with the batch asphalt mix plant ,the paper gives a solution to the problem. According to the analysis result of the used asphalt mixture,the traditional formula in construction norm and the results of comparing the theoretical calculating with the actural experiment ,a solution to the calculating in the maximum theoretical density formula is presented , the results of test show that solution is correct and capable.
