Abstract

The invention belongs to the technical field of pavement materials, and in particular relates to a municipal construction pavement material and a preparation method thereof. The municipal construction pavement material is made of the following components in parts by weight: 60-90 parts of asphalt, 25-40 parts of epoxy resin , stearic acid diethanolamide 2‑4 parts, acrylic anhydride 5‑10 parts, polyimide resin 5‑10 parts, kaolin 10‑20 parts, nano zirconium hydroxide 3‑6 parts, oleic acid 3‑6 parts . In the present invention, asphalt is used as the main base material, and the material is processed in stages. First, the epoxy resin is modified by using stearic acid diethanolamide, oleic acid and acrylic anhydride, and polyimide resin, nano zirconium hydroxide and Acrylic anhydride is used to modify asphalt; then the two modified materials are mixed with kaolin to increase the compressive strength, flexural strength, corrosion resistance and high temperature resistance of existing asphalt pavement materials, providing a long service life Municipal construction pavement materials.

Description

technical field [0001] The invention belongs to the technical field of pavement materials, and in particular relates to a municipal construction pavement material and a preparation method thereof. Background technique [0002] In my country, municipal facilities refer to various buildings, structures, equipment, etc. that are set up within the planning and construction scope of urban areas and towns (townships) and provide residents with paid or free public products and services based on government responsibilities and obligations, such as common Urban roads, bridges, subways, etc. Among them, road has the highest correlation with people's life, and it is also the most basic municipal engineering. [0003] According to different pavement materials, pavement can be divided into asphalt pavement, cement concrete pavement and other pavement. Asphalt pavement refers to the pavement structure in which a certain thickness of asphalt mixture surface is paved on the flexible base a...
