裂缝是高速公路病害的主要形式,采用合理灌缝材料和施工工艺对裂缝进行修补是高速公路耐久性的有力保证。应用新型沥青和丙酮改性环氧树脂灌浆对高速公路水稳层裂缝进行修补,结果表明:沥青改性环氧树脂灌浆综合了沥青和环氧树脂特点,具有良好的力学性、工作性、耐久性及修补性,与水稳层结合密实,能改善裂缝导致的薄弱环节来弥补原有缺陷,是水稳层裂缝修补的理想材料。
Crack is the main form of highway disease, the use of reasonable filling materials and construction technology to repair cracks is a strong guarantee for the durability of the highway. The application of new asphalt and acetone-modified epoxy resin grouting to repair the water-stable cracks in expressway showed that the grouting of asphalt modified epoxy resin integrated the characteristics of asphalt and epoxy resin, and has good mechanical properties, workability and durability Sexual and reparative nature, combined with the water-stable layer density can improve the weak links caused by cracks to make up for the original defects, is the ideal material for water-stable fracture repair.
