Abstract

The invention relates to a compound epoxy asphalt pavement material which is prepared from the following raw materials in parts by weight: 60 to 70 parts of coal tar pitch, 5 to 10 parts of emulsified asphalt, 15 to 20 parts of hydantoin epoxy resin, 15 to 20 parts of phenolic resin, 15 to 20 parts of bisphenol S type epoxy resin, 2 to 4 parts of stearyl diethanolamine, 3 to 5 parts of benzoic anhydride, 3 to 5 parts of polyamide resin, 3 to 5 parts of quartz sand, 3 to 5 parts of sodium silicate and 3 to 5 parts of calcium metasilicate. The invention further discloses a preparation method of the compound epoxy asphalt pavement material. The asphalt pavement material prepared in the method disclosed by the invention can resist 350 DEG C high temperature, can resist corrosion of sodium hydroxide solution, potassium hydroxide solution, oxalic acid solution and hydrochloric acid solution and further has good compressive strength and breaking strength; according to the material disclosed by the invention, an existing asphalt pavement material is improved, so that corrosion resistance and high temperature resistance are improved, and service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of construction engineering, and in particular relates to a composite epoxy asphalt pavement material and a preparation method thereof. Background technique [0002] Asphalt material is the most widely used material for road paving, including petroleum asphalt, coal tar pitch, liquid petroleum asphalt and asphalt emulsion.
