半刚性基层沥青路面反射裂缝的处治新技术

New Treatment Technology for Reflective Cracks of Semi-Rigid Base Asphalt Pavement

我国高速公路四通八达,为人们的交通出行提供便利,但日益增长的交通量和外界的环境因素给高速公路的正常使用带来损耗。高速公路的裂缝反复性问题和不可根治性,成为困扰高速公路养护领域的难题。国外裂缝处治技术的引进也没能解决这一难题。通过从包茂高速陕西段反射裂缝的处治方法中的材料和施工工艺等方面对半刚性基层沥青路面养护技术进行阐述,为其他高速公路的反射裂缝处治技术提供借鉴。

China's express ways extend in all directions,facilitating people's transportation,but the increasing traffic volume and external environmental factors bring losses to the normal use of expressways.The recurrence and irreversibility of cracks in expressway has become a difficult problem in the field of expressway maintenance.The introduction of crack treatment technology abroad also failed to solve this problem.The semi-rigid base asphalt pavement maintenance technology is expounded from the materials and construction techniques in the treatment method of reflection cracks in the Shanxi section of Baomao Expressway,which provides reference for the reflection crack treatment technology of other expressways.
