稀浆封层在公路工程上的应用

Slurry Seal Application in Highway Engineering

目前不少高速公路路面有早期损坏现象,特别是位处南方炎热多雨地区的高速公路,在通车后短短的几年内就出现了不同程度的早期损坏。造成这些破坏的重要原因之一是基层受水损害,其中包括已做的下封层未能真正起到防水、封水和联结的作用。国内一些高速公路采用稀浆封层技术代替传统的热沥青封层取得了较好的效果。本文结合江西彭泽至湖口高速公路的施工介绍稀浆封层技术的应用情况。

At present there are a lot of early Pavement damage,especially in a hot,rainy area located south of the highway,in just a few years after the opening appeared in the early damage in varying degrees.This destruction is one important reason for water damage affected the grassroots level,including under the seal has to do not really play a waterproof layer,sealing the role of water and connected.Some domestic highway instead of the traditional use of slurry seal and seal coat of hot asphalt to obtain good results.In this paper,to Hukou in Jiangxi Highway Construction Carassius introduced the application of slurry seal.
