Description

Technical Field

[0001] The utility model relates to the field of asphalt mixing tanks for asphalt pavement construction, in particular to an asphalt mixing tank for asphalt pavement construction. Background Art

[0002] Asphalt is a high-viscosity organic liquid. Asphalt can be mainly divided into three types: coal tar asphalt, petroleum asphalt and natural asphalt. Among them, coal tar asphalt is a by-product of coking, petroleum asphalt is the residue after crude oil distillation, and natural asphalt is stored underground. Asphalt is mostly used in construction, especially in road paving. Roads paved with asphalt and gravel are called asphalt roads.

[0003] In the prior art, modified asphalt is often required in the process of road paving. In the process of preparing the modified asphalt, the asphalt is often required to be heated before being injected into a mixing tank, and finally a modifier is added to the mixing tank to achieve modification.
