浅议沥青路面旧料再生利用

On Reclamation of the Old Material of Asphalt Pavement

随着公路和城市道路大规模建设及拓宽改建,大量翻挖的旧路面材料未得到充分利用,上海等大城市又缺少砂石材料,因此,探讨旧路面材料的再生利用十分必要。为解决再生利用、变废为宝及保护环境,结合有关方面研究,介绍了国内外应用概况及沥青路面旧料再生利用的热法再生和冷法再生技术方案,还就应用范围、途径以及质量控制等作了初探。

It' s necessary to discuss the reclamation of the old pavement materials,as there is short of materials of sand and stone in metropolises like Shanghai etc.,and with the construction,widening and reconstruction of highways and urban roads of great sizes,large quantities of old materials from excavated pavement have not been fully used.To resolve problems of reclamation and environmental protection,the application conditions both in home and abroad,technical schemes of heat&cold reclamation of asphalt pavement are introduced based on the relative study,as well as the discussion on application scope,method and quality control etc.
