摘要
通过室内试验 ,评价了SBR、SBS胶乳对乳化沥青蒸发残留沥青三大指标以及微表处混合料耐磨耗能力、抗车辙能力和抗裂能力的显著改善效果。通过某高速公路微表处养护工程的使用情况观测 ,验证了微表处混合料具有良好的路用性能 ,可有效修复车辙、改善路表功能和防止路表水下渗 ,但使用效果受原路面状况影响较大 ,可以用作高速公路沥青路面的预防性养护。
The effects of SBS and SBR on the index of asphalt emulsion residue such as softening point,penetration,ductility and index of Micro?surfacing mixture such as wet track abrasion,rut resistance and cracking resistance are studied through a series of tests The perfect performance of Micro?surfacing mixture is testified by the evaluation of Micro?surfacing which has been used on freeway It has been testified that Micro?surfacing can be used as rut?filling,friction course,water?proof surface,but its performance is affected remarkably by the original surface condition Micro?surfacing is an effective preventive maintenance method
