| 摘 要： | 为有效发挥喷涂型沥青路面养护材料的功能,根据防止或延缓沥青的老化性能,抵御水侵入路面结构内部的防水性能,以及抗滑性、耐久性和耐油污性等路用性能要求,采用5种不同喷涂型预防性养护材料进行研究,通过室内试验建立针对这类材料路用性能评价指标和方法。分析结果认为:添加养护材料的沥青老化前、后残留延度比能够较好地反映养护材料的抗老化性,良好的养护材料渗水系数应降低80%以上,其抗滑性以测得的摆值不低于沥青路面的验收标准,并可通过磨耗试验后摆值变化规律和车辙试验的动稳定度的降低程度分别建立喷涂型养护材料的耐久性和抗油污性的评价方法。

| Abstract: | In order to take advantage of the function of preventive maintenance materials spraying on asphalt pavement,five types of maintenance materials were studied in laboratory to establish their reasonable evaluation indices and evaluation methods according to their performance requirements,such as anti-aging property,water proofness,anti-slip performance,durability and oil resistance,etc.Analysis result shows that the remaining ductility ratio of asphalt before and after aging is better for representing the ant... |
