摘要:

优选低表面能材料及高温改制沥青为成膜物质,从表面自由能的角度研究了这种疏水型防护材料的抗水、抗冻黏及抗冻融黏附能力.结果表明：疏水型防护材料具有优异的抗水、冰破坏性能,能够有效降低冰与路表结构的冻黏力;随涂膜固化时间的延长,防护材料对湿轮磨耗试件表面细集料的黏附效果优异,抗水及耐冻融黏附性能显著提高.抗凝冰损伤疏水型防护材料的应用对促进沥青路面预防性养护新技术的发展具有重要意义.

Abstract:

The low surface energy material and high temperature modified asphalt are optimized as film material to test the hydrophobic protective material properties against water, ice and freeze thaw adhesion from the perspective of surface energy. The freezing adhesive characteristic and fine aggregate adhesion properties under different conditions were analyzed. The results show that the hydrophobic protective material can effectively reduce the freezing adhesive force between ice and road surface. With the increase of curing time, better performances in fine aggregate adhesion, water resistance and freeze thaw resistance are obtained in wet abrasion samples with protective material. The application of this hydrophobic protective material against ice is significant in the development of asphalt pavement maintainence technology.

Key words: asphalt pavement freezing microdamage hydrophobic protective material
