And wear layer construction method for preventive maintenance techniques

The present invention discloses a method for the wear layer preventive maintenance and construction techniques, a wear layer for preventive maintenance techniques include surface face the same way stresses thin wear layer, crumb rubber modified asphalt and the adhesive layer in connection the absorbent layer, the upper surface of the rubber powder modified asphalt adhesive layer connection wear thin layer, the lower surface of the rubber modified asphalt powder adhesive layer is connected to the stress absorbing layer. Shearing the present invention not only can eliminate the concrete cracks or crack dilation reflex asphalt concrete, asphalt rubber powder may also be utilized to good adhesion performance, the original cement concrete pavement, the stress absorbing layer, the adhesive becomes thin wear layer overall, forming a crack, impact, water seepage, anti-spalling good overlay, and ultimately achieve the purpose of curing a long time, it is significant.
