Abstract

The invention relates to road petroleum asphalt capable of adsorbing harmful gas and improving own strength and a preparation method of the road petroleum asphalt. The road petroleum asphalt comprises components in percentage by mass as follows: 90.0%-95.0% of matrix asphalt, 1.2%-2.5% of active carbon granules and 0.5%-1.0% of aluminium oxide particles. The preparation method of the road petroleum asphalt comprises the steps that the matrix asphalt is heated to a molten state, quinone compounds are added to the matrix asphalt and mixed uniformly, then the active carbon granules are added and stirred uniformly, diatomaceous earth is added, the aluminium oxide particles are added, silicon dioxide particles are added, and the materials are stirred uniformly. A road paved with the road petroleum asphalt has a function of adsorbing the harmful gas exhausted by an automobile, the strength of the road petroleum asphalt is better, and the road is not prone to deformation.

Description

technical field [0001] The invention relates to a road petroleum asphalt and a preparation method thereof, in particular to a road petroleum asphalt capable of absorbing harmful gases and improving its strength and a preparation method thereof. Background technique [0002] Asphalt is a dark brown complex mixture composed of hydrocarbons of different molecular weights and their non-metallic derivatives. It is a kind of high-viscosity organic liquid. It is liquid with a black surface and is soluble in carbon disulfide. Asphalt is a waterproof, moisture-proof and anti-corrosion organic gelling material. Pitch can be mainly divided into three types: coal tar pitch, petroleum pitch and natural pitch. Among them, coal tar pitch is a by-product of coking. Petroleum asphalt is the residue after distillation of crude oil. Natural bitumen is stored underground, and some form ore layers or accumulate on the surface of the earth's crust. Asphalt is mainly used in coatings, plastics,...
