中孟高速公路橡胶沥青应力吸收层的技术应用

自2006年以来,宁夏新建高速公路集中采用了路面分期实施的方法,以降低路基工后沉降对路面行车安全和舒适性的影响,但在路面下面层通车后的2-3年里,路面出现了不同程度的横纵裂缝,将影响到路面行车安全和路面的使用寿命。现以中宁至孟家湾高速公路为例,探讨橡胶沥青应力吸收层的功能和应用,为现阶段和未来若干年更多的水稳类半刚性基层高速公路在路面反射裂缝的处理,提供借鉴和参考。

Technical Application of Rubber Asphalt Stress Absorption Layer on Zhong-Meng Expressway

Since 2006,new highways in Ningxia have adopted the method of constructing pavement in phases so as to decrease the impact of driving safety and comfort due to subgrade settlement.Within 2-3 years of opening traffic after completion of binder layer,transverse & longitudinal cracks are seen on the pavement,which should be paid much attention.Otherwise the driving safety and using life of the pavement will be affected.Now taking Zhongning to Mengjiawan Expressway for example to discuss the function and applic...
