摘要
介绍了一种可以常年进行冷拌冷铺作业的路面修补材料——LB沥青材料。针对公路路面经常出现的溃烂和坑槽等病害,通过大量的室内与现场试验研究,分析了LB系列沥青及其混合料的路用修补性能,提出了简易可行的施工工艺。实际修补应用表明,LB沥青在路面修补中能够实现冷拌冷铺,使用效果良好,值得推广应用。
A new asphalt material-LB asphalt is introduced in this paper, which has been developed for the pavement mending and used all-year in cold mix and cold-application. Aiming at the usual damage of pavement, such as pot holes, ravelling etc. , and according to many test results obtained in laboratory and in place, the pavement mending performance of LB asphalt series and its mixtures are analyzed, a simple, easy and feasible operation procedure for the pavement maintenance is presented. The applications of this technique, by using LB asphalt series, show that the pavement mending can be realized in cold mix and cold-application with an ideal effect, and that it merits to be widely spreaded.
