摘　　要：为评价不同抗剥落措施改善花岗岩沥青混合料的路用性能,设计AC-10和AC-16花岗岩沥青混合料,通过马歇尔试验评价了不同抗剥落措施对花岗岩沥青混合料路用性能的改善效果。结果表明:界面联结剂的残留稳定度最大,但其热氧老化后的水稳定性低于偶岩复合改性沥青。青川岩沥青改性沥青混合料具有良好的高温抗车辙能力及耐老化性能,但低温抗裂性较差。SBS改性沥青混合料高温性能优异,但水稳定性仅比基质沥青混合料有所改善。偶岩复合改性沥青混合料具有突出的抗老化性和抗水损坏能力。In order to evaluate the pavement performance of granite aggregate asphalt mixture improved by different anti-spalling measures,AC-10 and AC-16 granite asphalt mixture were designed.The improvement effects of different anti spalling measures on the pavement performance of granite asphalt mixture were evaluated through Marshall test.The results show that the residual stability of interfacial binder is the largest,but its water stability after thermal oxygen aging is lower than that of matrix rock composite modified asphalt.Qingchuan rock asphalt modified asphalt mixture has good hightemperature rutting resistance and aging resistance,but poor low-temperature crack resistance.SBS modified asphalt mixture has excellent high temperature performance,but its water stability is only better than that of matrix asphalt mixture.Qingchuan rock asphalt and silane coupling agent composite modified asphalt mixture has outstanding aging resistance and water damage resistance.
