沥青砂浆中油砂比的确定方法

Method for Determining Oil-Sand Ratio in Asphalt Mortar

沥青混合料是目前工程领域使用较为广泛的一种路面材料,其配合比是影响其性能和使用状况的一个关键性的指标,所以,对于沥青混合料而言,配合比的确定至关重要。与之类似的沥青砂浆,其配合比应该怎么确定,一直是困难的问题。文章根据现在工程中所使用的沥青混合料的配合比,通过相同骨料表面积包裹相同数量的沥青的原理来计算沥青砂浆的油砂比,旨在类比沥青混合料的配合比计算方法,得出适用于沥青砂浆的配合比计算方法,以服务工程实践。

Asphalt mixture is a widely used pavement material in the engineering field at present, and its mix ratio is a key index that affects its performance and daily use. Therefore, the determination of the mix ratio is very important for the asphalt mixture.How to determine the mixing ratio of similar asphalt mortar has always been a difficult problem. In this paper, according to the mix ratio of asphalt mixtures used in current engineering, the oil-sand ratio of asphalt mortar is calculated by the principle of covering the same amount of asphalt with the same aggregate surface area. The purpose of this paper is to compare the calculation methods of the asphalt mixture, and to obtain the calculation method of the mixture suitable for the asphalt mortar to serve the engineering practice.
