旧水泥路面沥青加铺层防反射裂缝措施的应用与分析

摘要

针对旧水泥混凝土路面沥青加铺层结构中自粘式压缝带、热粘式压缝带、SAMI 应力吸收层、土工布及玻纤格栅等常用的五种延缓反射裂缝的处理措施，通过对其进行室内疲劳试验分析和室外试验评价，对比分析这五种处理措施的应用特点。%In this paper,the five common prevention measures against reflection crack that produced in asphalt concrete pavement covering an old cement concrete pavement have been introduced,including self-adhesive belt, thermal bonding belt,SAMI stress absorbing layer,geotextile and glass fiber grid. Through indoor fatigue tests and outdoor tests,comparison and analysis on application characteristic of the five prevention measures have been put forward.
