摘要 通过微纳米路表构建与超疏水材料涂覆技术相结合,制备了超疏水仿生水泥混凝土路面模型试件;开展超疏水材料涂覆技术研究,分析总结其制备工艺;采用自行设计的“冰-路”附着强度测试装置进行防覆冰性能测试,同时开展接触角测量试验、路面表面能计算及耐久性试验,综合评价超疏水仿生水泥混凝土路面的疏水、防冰效能。结果表明:超疏水水泥混凝土试件表面冰的残留率为29.9%,是普通试件的1/3左右,间接反映了超疏水路面具有较好的疏冰性能;与普通试件的接触角0°相比,超疏水水泥混凝土试件的接触角为153.5°,达到超疏水状态;表面能计算表明超疏水材料的作用降低了路面表面能,仅为普通水泥路面的3.4%,进一步验证了超疏水水泥混凝土路面可显著降低“冰-路”附着强度;通过模拟轮胎与路面的摩擦作用,接触角依然在90°以上,表明超疏水路面耐久性良好。

Abstract: The model of super-hydrophobic bionic cement concrete pavement was prepared, combining micro-nano pavement building with super-hydrophobic material coating technology. The coating technology of super-hydrophobic materials was studied and the preparation process was analyzed. Anti-icing performance was tested by self-designed ice-road adhesion strength testing device, the contact angle and durability were tested, the surface energy was calculated, then the anti-icing performance of super-hydrophobic bionic cement concrete pavement was evaluated comprehensively. The results indicate that the residual rate of ice on the surface of super-hydrophobic cement concrete specimens is 29.9%, which is about 1/3 of the common specimen, showing good anti-ice perfor-mance. The contact angle of the super-hydrophobic cement concrete specimen is 153.5°, while the contact angle of the common specimen is 0°. The calculation of surface energy reveal that the construction of the super-hydrophobic coating can reduce the surface energy, merely 3.4% of the ordinary cement pavement. It is further verified that the super-hydrophobic cement concrete pavement can significantly reduce the ice-road adhesion strength. The contact angle is still above 90° by simulating the friction between the tire and the road surface, indicating that the super hydrophobic pavement has good durability.
