通过对传统方法的分析,提出了沥青混合料集料比表面积确定的方法。沥青混合料的沥青膜厚度与其路用性能息息相关,计算沥青混合料沥青膜厚度之前,首先要确定集料的比表面积。通过对沥青混合料集料比表面积确定的传统方法和表面积系数的推导,认为现有的确定集料表面积的方法不够准确,然后通过矿粉和集料的表面积实测,提出了新的沥青混合料中集料表面积的确定方法。
Through the analysis of the traditional method, the method of determining the specific surface area of asphalt aggregate is proposed. Bituminous mixture asphalt film thickness and road performance is closely related to the calculation of asphalt mixture asphalt film thickness, the first to determine the specific surface area of the aggregate. Based on the traditional method of determining the specific surface area of aggregate and the derivation of surface area coefficient, it is considered that the existing method for determining aggregate surface area is not accurate enough. Then, based on the measured surface area of ore aggregate and aggregate, a new asphalt mixture Determination of aggregate surface area.
