环氧沥青厂拌热再生技术在高速路面养护中的应用

Research Status of Warm Mix Recycled Asphalt Mixture Technology

沥青路面厂拌热再生技术可实现路面铣刨料的回收利用,具有节能、减少污染、降低造价等特点。该文结合武黄高速公路路面专项养护工程,介绍了环氧沥青作为厂拌热再生胶结料的应用情况,主要对环氧沥青再生混合料配合比设计、施工工艺、路用性能三个方面进行阐述。试验段铺筑结果表明环氧沥青再生混合料能够实现RAP(废旧沥青混合料)完全利用,再生后综合路用性能优异,具有良好的推广应用前景。

Asphalt pavement plant mixing heat regeneration technology can realize the reuse of pavement milling recycling material,with the characteristics of energy saving,pollution reduction and cost reduction.Combined with the special maintenance project of Wuhuang Expressway pavement,this paper introduced the application of epoxy asphalt as a factory mixed heat regenerative cementitious,and mainly elaborated on the design,construction process and road performance of epoxy asphalt regeneration mixture.The results of the paving of the test section showed that the epoxy asphalt regeneration mixture can achieve full utilization of RAP,and the comprehensive road performance after regeneration is excellent,which has a good prospect for promotion and application.
