摘要本工作旨在探析聚氨酯基超薄磨耗层(Polyurethane ultra-thin friction course,PU-UTFC)混合料的层间粘结层在多种环境及荷载作用下的耐久性能退变规律。首先,基于层间斜剪与拉拔试验的粘结性能表征,对SBS改性乳化沥青、环氧树脂以及双组分聚合物防水粘结剂进行了比选;而后,通过室内试验模拟了所选取粘结层在紫外光照、高温、水损害环境中的老化及荷载反复作用下的疲劳行为;以SBS改性乳化沥青粘层为对照组,通过剪切及拉拔试验所测定的剪切强度、拉拔强度和破坏能指标,对比评价了双组分组合物防水粘结层在环境老化与荷载作用下的层间粘结性能。基于对比性试验研究,确定了双组分聚合物为PU-UTFC与沥青下卧层层间粘结材料,最佳涂覆量为0.8 kg/m²。性能评价发现,随着老化周期的增加,各因素影响下PU-UTFC的层间粘结性能均呈下降趋势,而且双组分聚合物粘层的各项性能始终优于SBS改性乳化沥青粘层;四种老化条件对层间粘结性能的影响程度排序为水损害老化＞荷载疲劳＞高温老化＞紫外老化。

Abstract: This work aims to explore the degradation law of the interlayer bonding layer of polyurethane ultra-thin friction course (PU-UTFC) mixture under various environmental and load conditions. Firstly, based on the interlayer shear and pull-out tests for bonding performance characterization, SBS modified emulsified asphalt, epoxy resin, and two-component polymer waterproof bonding agents were compared and selected. Then, indoor tests were conducted to simulate the effects of ultraviolet light, high temperature, water damage environmental aging, and load-induced fatigue on the selected bonding layer. With SBS modified emulsified asphalt bonding layer as the control group, the interlayer bonding performance of the two-component polymer waterproof bonding layer under environmental aging and load was evaluated by comparing the shear strength, pull-out strength, and energy of failure measured by shear and pull-out tests. Based on the comparative experimental study, it was determined that the two-component polymer was the interlayer bonding material for PU-UTFC and the underlying asphalt layer, with the optimal application rate of 0.8 kg/m². The performance evaluation found that with the increase of the aging cycle, the interlayer bonding performance of PU-UTFC under the influence of various factors all showed a downward trend, and the performance of the two-component polymer bonding layer was always better than that of the SBS modified emulsified asphalt bonding layer. The comprehensive ranking of the influence degree on the interlayer bonding performance is as follows:water damage aging＞load fatigue＞high temperature aging＞ultraviolet aging.

Key words: polyurethane mixture ultra-thin wear layer interlayer bonding environmental aging load fatigue performance deterioration comparative evaluation
