辉长岩骨料在沥青砼心墙施工中的适用性研究

Research on the Applicability of Gabbro Aggregate in Asphalt Concrete Core Wall Construction

原材料的选择是影响沥青混凝土心墙施工质量的一项重要因素。为了研究辉长岩骨料对沥青混凝土心墙施工的适用性,结合四川省米易县马鞍山水库工程的实际,从辉长岩骨料的化学成分、物理性能、与沥青的黏附性及现场应用效果等方面,对辉长岩骨料的适用性进行试验和分析,以求证辉长岩骨料适用性。

The choice of raw material is an important factor for the quality of asphalt concrete core wall construction. In order to study the applicability of gabbro aggregate as the raw material of asphalt concrete core wall,based on the practical status of Ma＇anshan Reservoir Project in Miyi County,Sichuan Province,we test and analysis the applicability of gabbro aggregate from the chemical compositions and physical properties of gabbro aggregate,its adhesion to asphalt,and the effect of its field application. It Proves that gabbro aggregate is applicable.
