泡沫沥青就地冷再生技术在公路养护工程中的应用

泡沫沥青冷再生作为一种对旧路面进行修复的技术,具有良好的抗疲劳和抗车辙性能,并能较好地解决铣刨旧料的堆放造成的环境污染问题。通过论述面层沥青混合料的配合比设计,确定最大干密度、最佳含水量和最佳泡沫沥青用量,并总结施工工艺,结果表明,泡沫沥青就地冷再生是一种有效的沥青路面养护方式。

Application of Foamed Asphalt Cold In-Place Recycling Technology in Highway Maintenance Project

Foamed asphalt cold in-place recycling can repair old pavements.It has good anti-fatigue and anti-rutting performance,and can solve the environmental problems of stacking the old milling-planning material.By discussing the mix design of surface asphalt mixture,it determines the maximum dry density,optimum water content as well as optimum foamed asphalt content,and summaries the construction technology.The research results indicate that foamed asphalt cold in-place recycling is an effective way for asphalt p...
