摘　　要：为高效解决冬季路面积雪结冰问题,提出了在路面铺设抗凝冰含砂雾封层的方法。首先,明确了抗凝冰含砂雾封层的材料配比、抗凝冰机理和制备工艺;然后,设计了融冰雪、除冰和冻融循环试验以验证其抑冰融雪的效果,同时进行了抗渗性、抗滑性和耐磨性试验以评价其路用性能。结果表明:抗凝冰含砂雾封层通过构筑疏水表面和释放融雪剂达到抗凝冰效果,其中疏水剂和抗凝冰剂的最优掺量分别为8%和40%;该材料可使路表冰雪量显著减少,并且经冻融循环作用后仍能保持除冰性能,表现出良好的除冰雪效果和耐久性;此外,其具备良好的抗渗性和耐磨性,虽其使原路面抗滑性略有降低,但仍能满足技术要求。To address the issue of ice and snow accumulation on the winter road surface efficiently,a solution involving the application of an antifreeze sand fog seal layer on the road surface was proposed.Initially,the composition,anti-icing mechanisms,and preparation procedures for the antifreeze sand fog seal layer were delineated.Subsequently,tests were conducted for ice-melting,de-icing,and freeze-thaw cycles to evaluate its ice-suppression and snow-melting efficacy.Concurrently,tests for permeability resistance,skid resistance,and abrasion resistance were performed to assess its road performance.Findings suggested that the ice prevention of antifreeze sand fog seal layer was accomplished via the establishment of a hydrophobic surface and the controlled release of de-icing agents,with the optimal proportions of hydrophobic and antiicing agents being 8%and 40%,respectively.The material not only significantly reduced the accumulation of ice and snow on the road surface but also sustained its de-icing efficacy following freeze-thaw cycles,thus demonstrating both effective ice-suppression and durability.Additionally,the seal exhibited good permeability and abrasion resistance;albeit a slight diminution in the skid resistance of the original road surface was noted,the seal still conformed to the requisite technical specifications.
