常温树脂类沥青路面裂缝灌缝材料的开发和应用研究

Crack Pouring Material′s Development and Application Research of Common-temperature Colophony Asphalt Pavement

根据多年公路养护经验而开发生产的常温树脂类沥青路面裂缝灌缝材料的原材料及制作工艺,对该灌缝材料的低温抗裂性、粘附抗脱性、高温稳定性等性能进行测试评价,并提出常温树脂类沥青路面裂缝灌缝的施工建议,对该灌缝材料的应用推广具有重要意义。

Combining with the raw material and production technology of common-temperature colophony asphalt pavement developed according to the highway maintenance experience of several years, crack pouring materials are conducted test appraisal in aspects of crack resistance under low temperature, adherence and stability under high temperature. Meanwhile the construction suggestion is put forward about this kind of crack pouring, which is of great significance to the material＇s popularization and application.
