掺加橡胶颗粒后的沥青混合料与普通沥青混合料相比产生了很大的变化,本文首先对影响这种新型混合料的配合比设计的因素进行分析研究,易确立的试验条件采用理论分析和单因素法确定后,主要对影响较大、取值范围较广的影响因素通过星点设计-效应面优化法进行分析研究,确定最佳条件。最后通过性能试验对设计结果进行验证。
Compared with ordinary asphalt mixture, the asphalt mixture with rubber particles has great changes. In this paper, the factors that affect the design of mixture ratio of this new mixture are analyzed and studied. The test conditions that are easy to establish are analyzed theoretically And single factor method, the influencing factors with larger influence and wider range of values are mainly analyzed and studied through the star point design-effect surface optimization method to determine the optimal conditions. Finally, through the performance test to verify the design results.
