沥再生在油田道路养护工程中的应用

Application of Recycled Asphalt in Curing of Oil Field Road

通过近几年"沥再生"在大庆油田专用道路上的应用,以工程实例及试验数据对涂涮前后沥青路面的3大指标进行对比,指出了"沥再生"这一产品的优越性。结果表明:"沥再生"对旧沥青路面具有明显的再生作用,能较大程度的恢复沥青性能,具有较好的弥合沥青路面细小裂缝和空隙的能力,从而改变旧沥青路面的老化程度和脆性,延长沥青路面的使用寿命,降低维护成本。

Based on application of recycled asphalt in special - pourpose road for Daqing oil field, from engineering example as well as by contrast with 3 targets of asphalt pavements before brushing and after that in testing data, the paper points out superiority of ＂Asphalt Recycling＂. Results of test indicates the recycled asphalt pavement possesses obvious recycling effect over the used asphalt pavement,would restore property of asphalt to a large extent and better close a rift and void of asphalt pavement, change the aging degree and friability of used asphalt pavement prolong the service life of asphalt pavement along with lower the safeguarding cost.
