Study on the sliding resistance and mechanical properties of two-component epoxy resin anti-sliding thin layer

To study the anti-sliding performance of the two-component epoxy resin thin layer, a combination of accelerated loading test and mechanical test was used to focus on the influence of different aggregate types on its anti-sliding performance. SMA-10 and modified emulsified asphalt micro-surface were selected as a control group, accelerated loading test were carried out, the law of BPN value, TD value, and aggregate wear mass loss rate with wear time were analyzed; and the logarithmic formula was used to make a fitting regression of the attenuation law of anti-sliding performance. Through shear test and pull-out test, the influence of different aggregate types and asphalt on its mechanical properties was analyzed. The test results showed that the anti-sliding performance of the two-component epoxy resin anti-sliding layer was better than that of SMA-10 and the modified emulsified asphalt micro-surface; within 3h after the start of the accelerated loading test, the anti-sliding performance decayed rapidly, and the later decay rate was slow and showed a slow decreasing trend. Besides, the relationship between the TD value and the BPN value with abrasion time had a good correlation with the logarithmic formula. In addition, the shear strength and bonding strength between the anti-sliding thin layer and the asphalt concrete base surface are strong, and the failure surfaces of the specimens all appear inside the asphalt layer.
