泡沫沥青冷再生技术在我国迅速发展并取得了较好的实际应用效果,随着我国重载交通逐年增多以及高温多雨等极端天气影响,早期修建的泡沫沥青冷再生路面已出现损坏现象,车辙、水损坏尤其严重。本文重点研究如何确定泡沫沥青铣刨料级配,以使回收料得到最大化利用并且使其再生混合料性能达到最优。分别对铣刨料级配和真实级配研究并进行级配设计,对两种不同筛分方法的再生混合料分别进行劈裂强度及马歇尔稳定度试验。由试验结果得出,泡沫沥青冷再生技术应采用真实级配进行再生混合料设计,以提高再生混合料的高温稳定性能及防水损坏性能。
泡沫瀝青冷再生技術在我國迅速髮展併取得瞭較好的實際應用效果,隨著我國重載交通逐年增多以及高溫多雨等極耑天氣影響,早期脩建的泡沫瀝青冷再生路麵已齣現損壞現象,車轍、水損壞尤其嚴重。本文重點研究如何確定泡沫瀝青鐉鑤料級配,以使迴收料得到最大化利用併且使其再生混閤料性能達到最優。分彆對鐉鑤料級配和真實級配研究併進行級配設計,對兩種不同篩分方法的再生混閤料分彆進行劈裂彊度及馬歇爾穩定度試驗。由試驗結果得齣,泡沫瀝青冷再生技術應採用真實級配進行再生混閤料設計,以提高再生混閤料的高溫穩定性能及防水損壞性能。

The mixture material of Foamed asphalt cold-recycled has rapidly developed in our country and has gotten excellent practical effect .With the annual increase of heavy traffic and the influence of high temperature and rainy and other extreme weather , on the foamed asphalt cold-recycled pavement early built has appeared damage phenomenon ,especially rut , water damage .The heavy point of the research is how to confirm the gradation of milling planer material so as to make good use of the recycle material and enable its performance of the regeneration mixture material to reach the optimal .The experiment re-searched milling gradation and real gradation and conducted gradation design .Splitting strength and Mar-shall stability tests are conducted on the regenerated asphalt mixture material of two kinds of different screening methods.According to the result of experiment,the cold recycled technique of foamed asphalt should adopt real gradation to do the regeneration mixture design so as to improve the high temperature stability and to prevent water damage performance of recycled asphalt mixture .
