Abstract

The invention discloses an environmentally friendly asphalt material and a preparation method of the environmentally friendly asphalt material. The process of the method is simple, the reaction condition is mild, the content of carcinogenic polycyclic aromatic hydrocarbons in the raw material is greatly reduced, no residues of a modifier and an accelerant are left, and the accelerant can be recycled. In order to fulfill the purpose, the invention provides the following technical scheme: the environmentally friendly asphalt material comprises the following parts: 15-20 parts of waste asphalt material, 120-150 parts of mineral aggregate, 1.5-5 parts of epoxy resin, 15-40 parts of cement, 3-5 parts of sodium sulphide, 0.5-10 parts of activated carbon, 0.5-3.0 parts of plant ash, 0.5-5 parts of magnetite, 0.5-3 parts of a coupling agent, 1-20 parts of a modifier and 1-20 parts of an accelerant.

Description

technical field [0001] The invention relates to an asphalt preparation method and belongs to the technical field of asphalt chemical modification.
