浅谈沥青路面冷补材料在公路养护中的应用

Application of Cold Patch Asphalt Pavement Material in Highway Maintenance

沥青路面养护受季节性影响严重,尤其是环境温度较低的冬季更为严重,按照常规养护方法,热拌沥青混合料还未运输到养护地点就已经摊铺不开,无法使用,既造成窝工浪费,又不能保证养护质量,因此,采用何种材料又好又快的处治路面病害,成为当前养护部门研究的重要课题。本文结合冬季气候、环境和实际使用情况,详细介绍了沥青路面冷补材料的生产工艺、实际应用,及造价分析,总结了应用冷补材料取得的效果,对今后冬季养护有一定借鉴作用。

The asphalt pavement maintenance are influenced by seasonal factor seriously, especially in winter. According to the conventional curing methods, the hot mix asphalt mixture even cannot be paved before being transported to maintenance site, which not only causes slowwork and waste, but also cannot guarantee the quality of maintenance. Therefore, to select a better material to control pavement diseases well and quickly has become an important subject of maintenance departments. Based on the winter climate, environment, and the actual usage, this article introduces the production technology, practical application and cost analysis of cold patch asphalt pavement materials, and summarizes the application effect of cold patch material, which has certain reference value to the winter maintenance in the future.
