浅谈再生沥青混合料的合理针入度范围

Discussion on recycled asphalt mixture's reasonable penetration range

主要通过测定不同旧料掺配率(0、20%、30%、40%)的再生沥青混合料的低温性能、车辙、水稳定性、劈裂强度和马歇尔指标,来分析得出再生混合料的合理设计针入度。

In this paper, severial indicators such as low temperature properties, rutting, water stability, split tensile strength and Marshall stability of recycled asphalt mixture （ different old materials admixture ratio ： 0% , 20%, 30% , 40% ） are measured, optimal penetration value of recycled asphalt mix is determined.
