摘　　要：针对城市道路中旧路面加铺沥青层面的需求增多,问题也逐渐增多的现象,为提高交通行车质量,优化城市形象,文章提出一种市政混凝土路面加铺沥青混凝土面层改造技术。对研究区域路面的强度与厚度、弯沉、接缝传荷能力和破损状况展开调查发现,反射裂缝是路面加铺沥青混凝土面层最常见的问题。为提高改造性能,在断裂力学的基础上分析反射裂缝产生的原因,根据分析结果设计市政混凝土路面加铺沥青混凝土面层改造技术,并通过马歇尔试验验证技术的有效性。In order to improve the quality of traffic and optimize the city image,a municipal concrete pavement adding asphalt concrete surface modification technology is proposed.Firstly,investigate the strength and thickness,deflection,joint load transfer capacity,and damage status of the pavement in the study area to determine the current situation of municipal concrete pavement in the study area.Through investigation,it is found that reflection cracks are the most common problem of asphalt concrete pavement.In order to improve the reconstruction performance,the causes of reflection cracks are analyzed on the basis of Fracture mechanics.Finally,based on the analysis results,a municipal concrete pavement overlay asphalt concrete surface modification technology was designed,and the eff ectiveness of the above technology was verified through Marshall testing.
