沥青混合料是一种比较复杂的复合型材料,它的物理力学性能和温度和矿料级配的组成直接相关。它是按照事先规定好的矿料级配类型,以及矿料中的粗细科技分析结果,与矿粉进行组成矿料配合比设计,然后再与不同的沥青用量及外加剂。根据最佳沥青用量,进行试拌合,试摊铺,成型碾压,检验沥青混合物在施工中的可行性,实际上是通过目标配合比设计、生产配合比设计和对生产配合比实验验证三个重要阶段,最后确定沥青混合料配合比。
Asphalt mixture is a complex composite material whose physical and mechanical properties are directly related to the composition of temperature and mineral gradation. It is in accordance with the provisions of a good mineral gradation type, as well as the thickness of the mineral science and technology analysis results, and the composition of mineral powder ore mix design, and then with a different asphalt dosage and admixture. According to the best amount of asphalt, the trial mix, test paving, molding rolling, testing asphalt mixture in the feasibility of the construction, in fact, through the goal of mix design, production mix design and production with the ratio of experimental verification of three An important stage, the final determination of asphalt mix.
