RAP掺量对SBS改性沥青热再生混合料性能影响分析

Analysis on Effect of RAP Content on Performance of Hot Recycled SBS Modified Asphalt Mixture

以废旧SBS改性沥青混合料为研究对象,测试了废旧沥青混合料料(RAP)掺量对热再生沥青混合料马歇尔稳定度、动稳定度、水稳定性、低温抗裂性、模量等技术性能的影响,提出了RAP的最佳掺配比例。

Taking the waste SBS modified asphalt mixture as the study object, the effect of waste asphalt mixture content on the technical performances of Marshall stability, dynamic stability, water stability, low temperature cracking resistance and modulus of hot recycled asphalt mixture is tested, and the optimizedmixing proportion of RAP is proposed.
