基于泡沫沥青再生层的路面结构研究

Based on Foam Asphalt Regeneration Layer of Pavement Structural Research

以回收的废旧路面材料(RAP)为基础,从材料的选取与级配的组成、沥青的最佳发泡条件、混合料拌合方法等几个方面初步得出一套基于路面结构层的泡沫沥青混合料配合比设计方法。并对材料的物理性质和强度特性进行了研究,提出了通过改变水泥和泡沫沥青的含量来确定再生泡沫沥青混合料在新生路面结构层中的使用范围。

Based on the recovery of waste materials （RAP）, a pavement layer of foamed asphalt mixture formula is designed according to the selection of materials and the composition of graded, asphalt in the best conditions of foam, mixing methods and mixture conservation program. The physical properties and strength of the material are researched. The range of the renewable foamed asphalt mixture which is used in the new structure of the surface layer is determined by changing the content of the cement and foamed asphalt.
