摘要
填缝料失效是导致水泥混凝土路面板破坏的主要原因。目前常用的填缝料使用寿命一般为1～3年，最长也只有5年，因此在混凝土路面的寿命周期内要多次更换填缝料：介绍一种新型长寿命填缝材料，其与混凝土路面寿命相同，用于高速公路可达30年。
Invalidation of joint fillers is a major cause for destruction of cement-concrete pavement slabs. At present the service lifetime of common joint fillers is in generally 1 -3 years, and maximally 5 years only, therefore, the joint fillers should be replaced for many times within the lifetime period of concrete pavement. This paper introduces a new-type joint filler with the same lifetime as that of concrete pavement up to 30 years when used for expressways.
