Abstract

The asphalt mixture thin overlay is usually paved on the basis of the original pavement sprayed with modified asphalt tack coat oil, and the paving thickness is generally controlled within 2-3cm. The thin overlay has the advantages of high strength, good durability, good skid resistance, fast construction speed, high efficiency and short open traffic time. It can effectively solve the problems of slight cracks, skid resistance, shallow rutting, water seepage and aging of pavement. Because the paving thickness of the thin overlay is only 2-3cm, it is difficult to guarantee the bonding force between the overlay and the original pavement layer, which is easy to appear the phenomenon of shear slip between the overlay and the original pavement layer under the load of vehicles, so the interlayer bonding between the overlay and the underlying layer is particularly critical in practical application. This study uses polymer modified asphalt provided by Nanjing limiqing New Material Technology Co., Ltd. in this paper, the bond performance between asphalt concrete and original pavement is tested by pull-out test to verify the bonding performance of the interface, which lays a foundation for the application of thin-layer overlay of asphalt mixture.
