摘要
为了得到阿拉沟水库沥青混凝土的配合比,文章通过试验得到沥青混凝土的配合比参数(矿料级配、沥青用量),继而.对配合比进行初步拟定,对于初选配合比制成的试件进行马歇尔试验,对试验结果进行分析确定出初选配合比,结合阿拉沟水库工程实际,对已经确定的初选配合比制成的沥青混凝土试件进行各种性能试验,得到满足阿拉沟水库工程需要的沥青混凝土配合比。对沥青混凝土原材料检测、沥青混凝土配合比的选择以及配合比的确定,可大大简化沥青混凝土配合比的试验过程,并可以给其他工程类似工程提供借鉴。
In order to obtain the mix ratio of asphalt concrete in Alagou Reservoir,the article obtained the mix ratio parameters of asphalt concrete(mineral gradation,asphalt dosage)through experiments,and then made a preliminary formulation of the mix ratio,and carried oul on the lest pieces made of the primary mix ratio Marshali test,analysis of the test results to determine the primary mix ratio,combined with the actual situation of thc Alagou Rescrvoir project,various performance tests were carried out on the asphalt concrete specimens made from the determined primary mix ratio to meet the necds of the Alagou Reservoir project xix ratio of asphalt concrete.The detection of the raw materials of asphalt concrete,the selection of the mix ratio of asphalt concrete and the determination of the mix ratio can greatly simplify the test process of the mix ratio of asphalt concrete,and can provide refrence for other similar projects.
