摘要
为研发以废油为稀释剂、沥青混合料回收料(RAP)为主要集料和沥青来源的路面坑槽冷补料,分别采用废机油、餐厨废油和柴油作为稀释剂制备冷补沥青,并基于冷补沥青布氏黏度、挥发性和储存稳定性测试结果探明了稀释剂最佳掺量;其次,在RAP掺量为70%时,通过冷补沥青混合料和易性和稳定度试验结果,确定了冷补料最佳沥青含量,并评价了其路用性能.结果表明:废机油、餐厨废油、柴油均具备稀释沥青的功能,其推荐掺量分别为35%,30%和25%(与沥青质量比),所制备的冷补沥青混合料在最佳沥青含量下各项性能合格,符合路面坑槽修补使用要求,其中以柴油-RAP冷补料的路用性能最优.
Abstract
To develop a pavement pothole cold patch material using waste oil as a thinner and Reclaimed Asphalt Pavement(RAP)as the main aggregate and asphalt source,cold patch asphalts were prepared u-sing waste engine oil,waste cooking oil,and diesel as thinners.The optimal dosage of the thinner was de-termined based on the results of tests for the viscosity of the cold patch asphalt,volatility,and storage sta-bility.Subsequently,with a RAP content of 70%,the optimal asphalt content for the cold patch material was determined through workability and stability tests of the cold patch asphalt mixture,and its road per-formance was evaluated.The results showed that waste engine oil,waste cooking oil,and diesel can all di-lute asphalt effectively,with recommended dosages of 35%,30%,and 25%,respectively.The cold patch asphalt mixture prepared at the optimal asphalt content demonstrated satisfactory performance in all as-pects.
