摘　　要：借鉴荷叶表面微构造特征,基于超疏水仿生理念,通过微纳米路表构建与超疏水涂层设计相结合,对传统水泥路面表层进行防覆冰、易除冰复合设计;分析超疏水材料的作用机理以及在路面应用的可行性,制备由主体结构混凝土层和超疏水-防覆冰层组成的路面板结构模型。对比超疏水路面和普通水泥路面表层的水滴接触角大小,分析其路面疏水性能;利用自主设计的"摆锤式附着强度"测试装置以及劈裂实验法测试试件"冰-路"附着强度。结果表明:对比普通水泥路面,超疏水-防覆冰路面表现出优良的超疏水性能,冰与路面的附着力大大降低,试验中残留附着冰的质量以及冰与路面的劈裂强度分别是普通水泥路面的36.80%和27.36%。Using the micro structure characteristics of lotus leaf surface for reference,based on the concept of super hydrophobic bionic,combining Micro-Nano pavement building with super hydrophobic coating design,traditional cement pavement was designed to prevent ice by multi-layer methods. The mechanism of super hydrophobic materials and the feasibility of its application to the pavement were analyzed,the pavement structure model of the main structure concrete layer and the super hydrophobic-anti icing layer was made. Compared to the contact angle of super hydrophobic surface and ordinary cement pavement,the surface hydrophobic properties were analyzed. Using the independent design test device of pendulum adhesion strength and split test method,the Ice-Road System adhesion strength of specimen was tested.Results indicate that super hydrophobic-anti icing pavement has a good hydrophobic effect and the surface adhesion of Ice-Road System is reduced greatly contrasting with ordinary cement pavement. The quality of the residual ice and the splitting strength of Ice-Road System in the test are 36. 80% and 27. 76% of the common cement pavement,respectively.
