Abstract

The interlayer bonding treatment technique has an important effect on the performance of double-layer drainage asphalt pavement. Based on the layer-by-layer paving technology, this paper studies the interlayer bonding treatment technology of double-layer drainage asphalt pavement. By changing the specimen preparation technology to simulate different paving processes, the bending tensile test of the joint surface, the bending tensile test of the double-layer mixture, the structure calculation of the double-layer pavement and permeable function were conducted to determine the effects of different treatment techniques for interfacial bonding layers. The main conclusions are: it is suitable to use high viscosity modified asphalt in the construction process. In the absence of double-layer paver in the domestic construction environment, it is feasible to use 'cold+hot' to construct double-layer drainage asphalt pavement. Spraying 0.1kg/m² modified emulsified asphalt adhesive layer between the layers can significantly enhance the pavement deformation resistance, while maintaining excellent water permeability.
