The invention discloses light polyurethane plastic paving material. The invention comprises a component A, a component B, composite catalyst and black micellar particles, wherein pulverized fuel ash is used in the component B as the packing material, the invention finds appropriate raw material ratio, and solves the flowablity of the pulverized fuel ash component, thus ensuring the traditional industrial refuse pulverized fuel ash to be converted into treasure from waste, so as to produce the light polyurethane plastic paving material with low cost and meeting the market demand, and therefore the invention not only is in favor of reducing the pollution of the pulverized fuel ash to the environment, but also can create good economic and social benefits. The light polyurethane plastic paving material obtained by utilizing the pulverized fuel ash production has the advantages that the weight is light, the specific surface is large after pavement, the pavement use amount of unit volume is reduced, the cost is greatly decreased, and each performance can achieve the national standards, therefore the invention provides a new broad prospect for the comprehensive utilization of the pulverized fuel ash, and makes contribution for the state to develop physical culture.
