Abstract

The invention discloses a biological asphalt material for roads and belongs to road construction materials. The biological asphalt material is prepared from the following raw materials in parts by weight: 10 to 30 parts of matrix asphalt, 5 to 18 parts of waste polymer material powder, 0.05 to 0.2 part of zinc oxide, 10 to 20 parts of a diluent, 0.5 to 4 parts of a homogenizing agent MS, 0.1 to 0.3 part of stabilizer sulfur, 0.05 to 0.2 part of an additive, wherein the additive is prepared from the following raw materials in parts by weight: 0.02 to 0.1 part of graphene powder and 0.03 to 0.1part of carbon nanotube. The biological asphalt material for the roads, disclosed by the invention, effectively recycles wastes and has the advantages of high toughness, good stability and the like when being used as a road construction material. The biological asphalt material for the roads significantly improves the strength, water stability and low temperature cracking resistance of the asphaltmaterial by adding graphene and the carbon nanotubes.

Description

technical field [0001] The invention relates to road building materials, in particular to a biological asphalt material for roads and a preparation method thereof. Background technique [0002] With the rapid development of road engineering construction in our country, the highway mileage has increased rapidly. This just needs a large amount of construction materials, and wherein, the consumption of bio-asphalt materials for roads is also very large. However, the existing bio-asphalt materials for roads cannot well meet the needs of road materials in use, have low strength and poor stability, and cannot effectively replace petroleum asphalt. [0003] Therefore, inventing a bio-asphalt material for roads with high strength and good stability has great practical value. Contents of the invention [0004] The invention provides a biological asphalt material for roads, which can solve the above-mentioned problems in the prior art. [0005] The invention provides a biological...
