Abstract

The invention discloses a color asphalt composition capsule and a preparation method thereof, and belongs to the technical field of a road material. The composition capsule is prepared from the following raw materials in parts by mass through mixing: 10 to 20 parts of inorganic pigment, 40 to 60 parts of decolorized asphalt, 20 to 35 parts of hydrated lime, 4 to 10 parts of organic montmorillonite, 0.5 to 1 part of zeolite and 0.04 to 0.06 part of water, wherein the organic montmorillonite is long-chain quaternary ammonium salt modified organic montmorillonite. Through the compounding of the inorganic pigment, the decolorized asphalt, the hydrated lime, the organic montmorillonite, the zeolite and the water, a color asphalt cementing material product of a capsule structure is prepared; thedifficult problem that the inorganic pigment and the asphalt can easily generate separation is effectively solved; the thermal oxidative aging resistant and ultraviolet aging resistant performance ofthe color asphalt is improved; meanwhile, the release of volatile organic compounds can be inhibited; the problem of environment pollution of the existing color asphalt cementing material is solved;in addition, the liquid state of the color asphalt cementing material can be effectively maintained without energy consumption, so that the energy source consumption in the transportation process is reduced.

Description

technical field [0001] The invention belongs to the technical field of road materials, in particular to a colored asphalt composition capsule and a preparation method thereof Background technique [0002] Colored asphalt pavement refers to the color asphalt concrete pavement with certain strength and function that is formed by mixing and mixing materials such as decolorized asphalt, stones, pigments and additives at a specific temperature to prepare colored asphalt concrete, and then paving and rolling. . In terms of traffic management, colored asphalt pavement can induce traffic and make traffic management more intuitive. Using color to indicate and distinguish road sections or lanes with different functions can improve the driver's alertness and recognition effect, increase road capacity and traffic. Safety. Therefore, colored asphalt pavement can play a greater role in promoting road traffic safety and beautifying the road space environment than ordinary asphalt concret...
