Wearing layer for preventive maintenance technology

The utility model discloses a wearing layer for preventive maintenance technology. The wearing layer comprises an ultrafine wearing layer, a rubber powder modified asphalt adhesive layer and a stress absorbing layer connected to the upper surface of the original pavement, wherein the ultrafine wearing layer is connected to the upper surface of the rubber powder modified asphalt adhesive layer, and the stress absorbing layer is connected to the lower surface of the rubber powder modified asphalt adhesive layer. The wearing layer is capable of eliminating the shearing action of cement concrete cracks or the expansion of asphalt concrete reflection cracks, and also capable of integrally bonding the original cement concrete pavement, the stress absorbing layer and the ultrafine wearing layer together by virtue of excellent bonding performance of rubber powder asphalt to form an excellent crack-resistant, anti-shock, watertight and anti-slipping overlay, and finally, the purpose of long maintenance time is achieve
