Environmentally-friendly highway material

Abstract

The invention discloses an environmentally-friendly highway material. The environmentally-friendly highway material is characterized by comprising the following ingredients in parts by weight: 100-150 parts of gravel, 12-15 parts of diatomite, 5-9 parts of sepiolite, 6-8 parts of medical stone, 1-3 parts of perlite, 1-2 parts of tourmaline anion powder, 5-14 parts of stearic acid, 9-18 parts of stearate, 8-12 parts of stearic amide, 2-9 parts of hollow glass bead, 1-9 parts of graphite powder, 3-7 parts of kaolin, 4-9 parts of wood fiber (80-100 meshes), 6-9 parts of diatomite (80-100 meshes), 7-8 parts of open pore expanded perlite (20-120 meshes), 5-8 parts of hollow glass bead (120-200 meshes), 6-9 parts of lime, 14-28 parts of gypsum, 3-9 parts of fiber and 3-9 parts of foaming agent. The environmentally-friendly highway material disclosed by the invention has the beneficial effects of better construction workability, shorter open traffic and longer effective compaction time, so that the road construction quality is improved.

Description

technical field [0001] The invention relates to a green environmental protection road material. Background technique [0002] At present, more than 90% of paved road projects in my country are paved with asphalt mixture. Compared with cement pavement, asphalt pavement has the advantages of excellent road performance, convenient maintenance, low driving noise, and low construction cost. However, in the process of construction and use, the existing asphalt mixture has the following shortcomings. Construction at high temperature can easily cause asphalt aging. Because traditional base asphalt and modified asphalt have high viscosity at high temperature, such high construction temperature is very easy to cause asphalt aging. The aging of the asphalt pavement affects the long-term performance and service life of the asphalt pavement, so that early diseases occur frequently, which is also a main reason for the frequent road maintenance problems that the people complain about and ...
