浅谈高速公路养护新技术

对于高速公路,安全舒适的铺装路面和耐久性构造设计,是一个非常重要的课题。然而,由于路基层上面雨水长时间滞留,基层以下的沥青混凝土出现剥离现象。因此,针对高速公路铺装的构造诊断的非破坏评价方法,国外利用搭载研制的FWD(Falling Weight Deflectometer)装置的车辆进行路面构造诊断。

New technology of maintenance for highway

Safety and comfortable paving roads and durability structure design are very important for highway. However, due to the rain resort long time on road,the asphalt concrete under grass roots always peel off. Therefore, in view of the non-destructive evaluation method for pavement structure diagnosis of highway, Falling Weight Deflectometer (FWD) device carrying by vehicles are used to diagnose pavement structure in foreign countries.
