Abstract

The invention discloses an anti-skid anti-icing night visible asphalt pavement material and a preparation method thereof. The asphalt pavement material comprises the following components in parts by mass: 50-65 parts of steel slag coarse aggregate, 20-30 parts of steel slag fine aggregate, 10-15 parts of waste glass fine aggregate, 3-5 parts of filler containing a phase change material and 3.8-5.1 parts of modified asphalt. The preparation method comprises the following steps: mixing coarse and fine aggregates, and then respectively heating the coarse and fine aggregates, the filler containing the phase-change material and the modified asphalt; then putting the heated mixed aggregate into a stirring pot which is preheated in advance for stirring, and then sequentially and respectively adding the heated modified asphalt and the filler containing the phase-change material for stirring. The asphalt pavement material has good skid resistance and wear resistance, the thermal performance of the pavement is improved, and the icing resistance of the pavement is improved; meanwhile, the night visibility of the asphalt pavement is enhanced, the preparation process is simple, the cost is low, the source is wide, and high-added-value utilization of the steel slag and the waste glass is realized.

Description

technical field [0001] The invention belongs to the technical field of road engineering materials, and in particular relates to an anti-skid and anti-icing-visible asphalt pavement material at night and a preparation method thereof. Background technique [0002] Road traffic safety has always been the focus of widespread attention, especially in winter road traffic safety has its particularity and importance. For example, in areas with a large temperature difference between day and night, the road surface is very icy in winter, which will reduce the friction between the wheels and the road surface, which is easy to slip and cause traffic accidents. At the same time, poor visibility conditions for driving at night, especially on suburban roads, rural roads and expressways far away from urban areas, and poor roadside lighting also increase traffic safety hazards. Asphalt pavement is comfortable to drive, easy to maintain, and high in traffic efficiency. It is the mainstream p...
