摘要:
以微纳解交联胶粉为原料,采用高温高速剪切的方法制备了微纳橡胶沥青,使用扫描电子显微镜、透射电子显微镜、X射线光电子能谱仪探究了微纳橡胶的微观形貌及微纳橡胶和基质沥青的混溶过程,通过油石比设计研究了混合料的水稳定性、温度稳定性、抗劈裂破坏性能等路用性能,此外还进一步评估了微纳橡胶沥青混合料在实际道路工程中的应用效果。结果表明,解交联胶粉中溶胶质量分数可达65.7%,其中解离炭黑的尺寸约为200 nm,在微纳橡胶与沥青溶混过程中发生了硫交联键化学作用;微纳橡胶沥青混合料具有优异的水稳定性、高低温稳定性能和抗劈裂破坏性能;使用微纳橡胶沥青混合料铺筑的甘肃省酒泉—嘉峪关绕城高速公路试验路段全厚式微纳橡胶沥青路面上面层和下面层的关键技术指标均符合规范及设计要求。
Abstract:
Micro-nano rubber asphalt was prepared by high-temperature and high-speed shearing with micro-nano degraded rubber powder as raw material, and the micromorphology of micro-nano degraded rubber powder and miscible process of micro-nano rubber rubber and substrate asphalt were investigated by scanning electron microscopy, transmission electron microscopy and X-ray photoelectron spectrometer, and the road performance of micro-nano rubber asphalt mixture including water stability, temperature stability and cracking failure resistance were studied by the design of asphalt aggregate ratio. In addition, the application effect of micro-nano rubber asphalt mixture in practical road engineering was further evaluated. The results showed that mass fraction of sol in degraded rubber in which the size of dissociated carbon black was about 200 nm reached 65.7%, and the interaction of sulfur cross-linked bond between degraded rubber and asphalt appeared during the miscible process; the micro-nano rubber asphalt mixture showed excellent water stability, high- and low-temperature stability and cracking failure resistance; the key technical indexes of the upper layer and the lower layer in full-depth rubber asphalt pavement of test section of Jiuquan-Jiayuguan ring expressway prepared by using micro-nano rubber asphalt mixture in Gansu province all complied with the specifications and design requirements.
