泡沫沥青冷再生实验室试验研究

Test Study of Foamed Asphalt Cold Recycling

利用沪宁高速公路扩建工程铣刨旧料为原材料,采用WLB10泡沫沥青发生装置,对沥青发泡的性能进行了研究,并探讨了泡沫沥青冷再生混合料配合比设计方法,通过对泡沫沥青再生混合料与热拌沥青混合料性能的比较,提出了泡沫沥青再生的使用范围。

Using the old bituminous mixture of Huning expressway expanding construction and the WLB10 foamed asphalt producing device, performance of the foamed asphalt and the design method of foamed mixture formula are studied.Comparing the performance between the foamed asphalt mixture and the hot asphalt mixture, the use area of foamed asphalt cold recycling is presented.
