摘　　要：在旧沥青路面补强中,基层类型是影响道路后续使用性能的重要因素。文中以厦门市民安大道为例,通过采取表观调查、破损分析、弯沉检测等多种方法对现状路面进行综合分析,准确判断了现状路面的实际状况,并分析了病害产生的原因,针对性地提出了柔性基层与半刚性基层两种路面补强方案。研究分析和工程实践证明,柔性基层补强方案既能降低对现状交通的影响,又可以有效减少路面反射裂缝,方案可靠有效,改造后路面能够满足结构强度与行车舒适性要求。In the reinforcement of old asphalt pavement, the type of base course is an important factor affecting the subsequent performance of the road. Taking Min’an Avenue in Xiamen City as an example, this paper comprehensively analyzes the current pavement by adopting various methods such as appearance investigation, damage analysis, deflection detection, etc., accurately judges the actual situation of the current pavement, analyzes the causes of the disease, and puts forward two pavement reinforcement schemes, namely flexible base and semirigid base. The research analysis and engineering practice prove that the flexible base reinforcement scheme can not only reduce the impact on the current traffic, but also effectively reduce the pavement reflection cracks. The scheme is reliable and effective, and the reconstructed pavement can meet the requirements of structural strength and driving comfort.
