摘　　要：为使浇注式沥青混合料设计时体积特征更明确,最佳沥青用量来源更有依据,采用土工击实试验方法确定合成级配的矿料间隙率,并按照常温下沥青刚好填满矿料间隙的假设换算沥青用量和有效沥青用量,然后进行混合料性能试验。试验结果表明,该沥青用量符合浇注式沥青混合料经验用油量范围,且混合料性能试验结果满足相关要求,说明浇注式沥青混合料体积设计法具有实用性和可行性。In order to make volume feature of pouring asphalt mixture more clearly during design, and the source of the optimum asphalt content more clearly warranted, the soil compaction test is used to define the synthesis gradation of VMA. And the asphalt content and effective asphalt content are calculated according to the assumption that asphalt is filled the VMA exactly at normal temperature. And then the mixture performance is tested. The test result shows that this asphalt content satisfies the experienced content range of pouring asphalt mixture, and the test result of mixture performance satisfies the relative requirements, which show that the volume design method of pouring asphalt mixture is practical and feasible.
