Abstract

ABSTRACT The ageing property of the asphalt binder is time-dependent. A time-dependent short term ageing property of 80/100 penetration grade bitumen and the possibility of waste engine oil rejuvenation for the highly aged asphalt binder performance were investigated. Four specimens of equal weight from the penetration grade-80/100 bitumen are collected. The first specimen was checked for quality requirements. The other three specimens were aged using rolling thin film oven for 85, 115, and 145 minutes to simulate the delay during hot mix asphalt production, hauling, and compaction. The highly aged bitumen was rejuvenated with 2%, 5%, and 10% Waste Engine Oil by weight. Results indicated that as the ageing time increased, penetration and ductility decreased, softening point, flash point, fire point, and mass loss increased. A conventional test showed that highly aged bitumen from the trial period was 145 minutes and 10% waste engine oil obtained the optimum dosage. Further, multiple stress creep recovery analyses indicated the rejuvenated binder is prone to pavement rutting above 70°C, and rejuvenation is effective for pavement temperature below 70°C. Hence, exposing the asphalt binder for temperature for a more extended period affects pavement performance.

废机油对高短期老化沥青粘结剂的回用效果评价
摘要沥青结合料的老化性能与时间有关。研究了80/100渗透级沥青的随时间变化的短期老化性能,以及高老化沥青结合料性能中废机油再生的可能性。从渗透等级为80/100的沥青中收集了四个同等重量的试样。检查了第一个样品的质量要求。其他三个试样使用滚动薄膜烘箱老化85、115和145分钟,以模拟热拌沥青生产、运输和压实过程中的延迟。用2%、5%和10%(重量)的废机油使高度老化的沥青再生。结果表明,随着时效时间的增加,渗透性和延展性降低,软化点、闪点、燃点和质量损失增加。常规试验表明,试验期的高老化沥青为145分钟,10%的废机油获得了最佳用量。此外,多重应力蠕变恢复分析表明,再生粘结剂在70°C以上容易产生路面车辙,再生对70°C以下的路面温度有效。因此,沥青结合料在温度下暴露更长时间会影响路面性能。
