热再生技术在我省高等级公路沥青路面中的应用

Application of Hot Recycling Technology in the Construction of High Grade Highway of Qinghai Province

通过沥青路面热再生技术在我省高等级公路沥青路面的应用,解决西宁周边路龄较长的马平西等路段沥青路面存在严重车辙、裂缝、泛油、松散、粗细集料离析、划痕病害等问题,提升我省高等级公路路面使用性能(PQI)。并对多年来的实际应用、效果持续跟踪观测、存在问题进行详细分析总结,结合我省高寒气候特点,为再生路段的长期路用性能以及不同病害采取相应的再生方案的比较、分析提供了理论依据和宝贵经验。同时,对降低养护成本,节能减排,预防性养护等意义重大。

To improve the pavement performance of high grade highway of Qinghai Province, and find solutions to highway diseases of ruts, cracks, pavement bleeding, pavement raveling, aggregate segregation and scratches of highways near Xining city, the hot recycling technology is introduced in this paper. And through long - term observation and relevant analysis on the effect of hot recycling technology, combining with the cold and frigid elimate of Qinghai, ward, which has reduction. the application plan of hot recycling technology for the highway construction of Qinghai is put forsignificance in reducing maintenance cost, preventative maintenance, energy saving and emission
