摘要
影响沥青混凝土面层质量的因数有很多,其中沥青混凝土集料级配是一个重要的影响因数。宜昌市某一级公路沥青混凝土面层试验段施工中分别采用不同的集料级配进行面层摊铺。本文以此一级公路面层试验段为依托,将外观质量、压实度、弯沉、摩擦系数四个重要指标作为评定质量的标准,初步研究集料级配对沥青混凝土面层施工质量的影响。
There are many factors that affect the quality of asphalt concrete surface,among which the aggregate grade of asphalt concrete is an important one.Different aggregate grades are used to pave the asphalt concrete pavement in the construction of the test section of the first-class highway in Yichang city.Based on the test section of the first-class highway surface,taking four important indexes of appearance quality,compactness,deflection and friction coefficient as the evaluation standard,this paper makes a primary study of the influence of aggregate grade on the construction quality of asphalt concrete surface.
