  要:多年实践也表明,半刚性基层沥青路面结构反射裂缝问题难以解决。因此国内外纷纷开始了沥青混凝土路面柔性基层的研究工作,以丰富沥青路面结构形式。鉴于此,东萌公司在建项目(陕西水阳高速LM-1标)联合长安大学课题组,结合陕西省高速公路沥青路面目前常用的路面结构型式及其使用过程中存在的问题,根据陕西省气候、交通以及材料特点等,对大粒径沥青混合料(LSPM)柔性基层的材料组成设计、技术性能评价指标、路面结构组合方式以及施工工艺与质量控制等一系列问题进行系统性研究与实践。

Abstract: Base on many years practice, semi-rigid base asphalt pavement structure also has some defects and shortcomings that couldnt be solved In view of this, combined with the common pavement structure types and existing problems in the use process of Shaanxi expressway asphalt pavement, according to the climate, traffic and material characteristics of Shaanxi Province, the material composition design and technical performance of large-size asphalt mixture (LSPM) flexible base course, series of problems, such as evaluation index, pavement structure combination mode, construction technology and quality control, were systematically studied and practiced by construction project of Dongmeng Company(Shaanxi Shuiyang High Speed LM-1 Standard) and research team of Changan University.
