摘要
为了提高半刚性基层沥青路面的建设水平,文章依托某国道一级公路,分析了路面反射裂缝、车辙等病害的产生原因,通过ABAQUS软件建立计算模型,分析了反射裂缝的受力和车辙的变形规律,同时提出了采取加铺玻纤格栅、确定基层预切缝间距等措施来处治路面病害,研究成果可为类似项目提供借鉴.
Abstract
In order to improve the construction level of semi-rigid base asphalt pavement,this paper analyzes the causes of pavement reflection cracks,ruts and other diseases based on a national first-class highway.The calculation model is established by ABAQUS software,and the stress of reflection cracks and the deformation law of ruts are analyzed.At the same time,measures such as paving fiberglass bars and determining pre-cutting joint spacing at the base are proposed to treat pavement diseases.The research results can provide reference for similar projects.
