Abstract

Ultra-thin wear layer is a preventive maintenance technology that can improve flatness, wear resistance and reduce the noise. In order to prevent delamination of the wearing layer and ensure the continuity between the layers, it is necessary to use high-viscosity emulsified asphalt between the layers. In this study, a certain proportion of high molecular polymers and latex were added as tackifiers to make the prepared emulsified asphalt have better stability and cohesiveness. Experiments are conducted to study the influence of factors such as stabilizers, polymer and latex on the evaporation residue and storage stability of high-viscosity emulsified asphalt, and to design the compatibility of raw materials for high viscosity emulsified asphalt. The study found that the high-viscosity emulsified asphalt prepared by the water-soluble emulsification method under the conditions of quaternary ammonium salt emulsifier 1.5% + ammonium chloride 0.4% + neoprene latex 3% + high molecular polymer 0.7% has good performance. Through the interlayer shear and tensile test, the strength is greater than 0.4Mpa.
