摘　　要：为研究双组分环氧树脂抗滑薄层的抗滑性能,采用加速加载试验与力学试验相结合的方法,重点探讨了不同集料类型对其抗滑性能的影响。选择SMA-10与改性乳化沥青微表处作为对照组,开展加速加载试验,分析了BPN值、TD值、集料磨耗质量损失率随磨耗时间变化的规律;采用对数公式对抗滑性能的衰减规律进行了拟合回归。通过剪切试验与拉拔试验,分析了不同集料类型与沥青层基面对其力学性能的影响。试验结果表明:双组分环氧树脂抗滑薄层的抗滑性能优于SMA-10与改性乳化沥青微表处;加速加载试验开始后3 h内,抗滑性能衰变速度较快,后期衰减速度较慢并呈缓慢降低趋势;TD值与BPN值随磨耗时间变化的关系与对数公式呈较好的相关性;抗滑薄层与沥青混凝土基面间的剪切强度与黏结强度较高,试件的破坏面均出现于沥青层内部。In order to study the anti-skid performance of two-component epoxy resin anti-skid thin layer,the accelerated loading test and mechanical test were combined to discuss the influence of different aggregate types on their anti-skid performance.SMA-10 and the modified emulsified asphalt micro-surfacing were selected as control group to carry out the accelerated loading test.The variation rule of BPN,TD and aggregate abrasion mass loss rate changing with time was analyzed,and the attenuation law of anti-skid performance was fitted and regressed by logarithmic formula.Through shear test and drawing test,the influence of different aggregate types and asphalt base surfaces on their mechanical properties was analyzed.The experimental results show that:the skid resistance of the two-component epoxy resin anti-skid thin layer is better than that of SMA-10 and the modified emulsified asphalt micro-surfacing;within 3 hours after the start of accelerated loading test,the attenuation speed of anti-skid performance is relatively fast,and the attenuation speed is slow in the later stage and trends to decrease slowly;the relationship of TD and BPN changing with wear time has a good correlation with logarithmic formula;the shear strength and bond strength between the anti-skid thin layer and the asphalt concrete base surface are relatively high,and the failure surfaces of the specimens occur inside the asphalt layer.
