A kind of anti-skid anti-icing-night visible asphalt pavement material and preparation method thereof

Abstract

The invention discloses an anti-skid and anti-icing-night visible asphalt pavement material and a preparation method thereof. In parts by mass, the asphalt pavement material includes the following components: 50-65 parts of steel slag coarse aggregate, 20-30 parts of steel slag fine aggregate, 10-15 parts of waste glass fine aggregate, filler containing phase change material 3 ~ 5 parts and modified asphalt 3.8 to 5.1 parts. The preparation method is as follows: after mixing coarse and fine aggregates, heating them with fillers containing phase change materials and modified asphalt respectively; then putting the heated mixed aggregates into a preheated mixing pot to mix, and then adding them in turn. The heated modified asphalt and the filler containing the phase change material can be mixed. The asphalt pavement material has good anti-skid and wear-resistant properties, improves the thermal properties of the pavement, improves the anti-icing ability of the pavement, and at the same time enhances the visibility of the asphalt pavement at night, and has the advantages of simple preparation process, low cost, and low cost. It can realize high value-added utilization of steel slag and waste glass.

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-night-visible asphalt pavement material and a preparation method thereof. Background technique [0002] Road traffic safety has always been the focus of widespread concern, 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, and it is easy to slip and cause traffic accidents. At the same time, the visual conditions of driving at night are poor, especially the suburban roads, rural roads and highways far away from the urban area, and the roadside lighting is poor, which also increases the hidden danger of traffic safety. Asphalt pavement is the mainstream pavement at home and abroad because of its comfort...
