Technical Field

[0001] The utility model relates to the field of asphalt blanking, in particular to an asphalt blanking barrel capable of reducing waste. Background Art

[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, mostly existing in liquid or semi-solid petroleum form. It has a black surface and is soluble in carbon disulfide and carbon tetrachloride. Asphalt is an organic cementitious material that is waterproof, moisture-proof and anti-corrosive.
