摘要
文章分析和阐述了依托工程高模量沥青混合料在材料选择、配合比设计、性能测试和施工等方面的特点,并从技术和管理方面提出性能保障措施;研究表明:与传统混合料相比,高模量沥青的重组分含量更高,而且矿料中的粗集料更坚硬,细集料和沥青含量更多,高模量沥青混凝土的综合性能优异,施工后对路面弯沉值进行测试发现其施工质量良好,可为高模量沥青混凝土路面施工提供参考。
This article analyzes and elaborates on the characteristics of high modulus asphalt mixture in material selection,mix design,performance testing,and construction based on engineering,and proposes performance guarantee measures from the technical and management aspects.Research has shown that compared with traditional mixtures,high modulus asphalt has a higher content of heavy components,and the coarse aggregate in the aggregate is harder,with more fine aggregate and asphalt content.The comprehensive performance of high modulus asphalt concrete is excellent.After construction,testing the pavement deflection value found that its construction quality is good,which can provide reference for the construction of high modulus asphalt concrete pavement.
