Document Type and Number:
WIPO Patent Application WO/2023/115672
Kind Code:
A1
Abstract:
An asphalt modifier, and a preparation method therefor and the use thereof. The asphalt modifier comprises the following raw materials, in parts by weight: 15-60 parts of a thermoplastic elastomer, 10-35 parts of a polyurethane elastomer, 15-40 parts of a petroleum resin, 5-20 parts of a heat-sensitive resin, 1-5 parts of a stabilizer and 1-10 parts of a plasticizer. The asphalt modifier can be quickly melted and dispersed in an asphalt mixing tank, such that the viscosity of asphalt at the usage temperature can be significantly improved, and the pavement use performance of the mixture is ensured; the construction viscosity of the asphalt at a high temperature can be effectively reduced, the construction workability of the mixture is improved, and the melt dispersion characteristic of the asphalt modifier is further improved; and the preparation method therefor is simple and convenient for production and application.
