Abstract

The invention relates to a high-viscosity asphalt additive modifier and a preparation method thereof. The high-viscosity asphalt additive modifier is prepared from, by weight, 100 parts of thermoplastic resin, 10-20 parts of viscosity resin, 20-30 parts of EVA and 1-2 parts of zinc stearate. The invention further relates to a high-viscosity modified asphalt and a preparation method thereof. To solve the problem of traditional high-viscosity modified asphalt, the high-viscosity asphalt additive modifier with low cost and good performance is provided, the high-viscosity modified asphalt is not needed to be prepared in advance, only the modifier is manually or automatically added in a asphalt mixture when in use, and the high-viscosity modified asphalt mixture is then formed after aggregating, shearing and stirring are conducted in sequence.

Description

technical field [0001] The invention relates to the technical field of high-viscosity modified asphalt, in particular to a high-viscosity asphalt externally mixed modifier and a preparation method thereof, and a high-viscosity modified asphalt and a preparation method thereof. Background technique [0002] Permeable asphalt pavement, that is, the pavement pavement material used has good water permeability, and all or part of the surface precipitation can pass through the pavement and go directly into the ground. The permeable pavement can balance the urban ecosystem. A considerable part of the rainwater can penetrate into the ground through the permeable pavement. When the rainfall is small, the drainage system may not be needed to solve the problem of ground water accumulation. When the rainfall is large, it will greatly relieve the pressure on the urban drainage system, which can It greatly shortens the time for removing ground water, and for a few low-lying road sections,...
