摘要
Abstract
The article analyzes the influence law of the amount changing of cement on the physical and mechanical properties, water stability, shear resistance and high temperature stability of foam asphalt through laboratory tests and theoretical analysis. The results show that the cement can effectively improve the performance of the cold recycling mixture with foamed asphalt, because it can be used as high-quality fine aggregate, and can generate new material with higher viscosity and strength in the reaction with as-phalt due to its alkaline and hydraulic;when the cement amount increases from 0 to 3%, the mixture po-rosity is decreased by 1.2%, the residual strength ratio is increased by 22.15%, the dynamic stability after 7 days′ cure also is increased by about 65%, and when being used as the adhesive layer, the adhesive force to the surface and base is increased by 0.88MPa and 0.54MPa.关键词
