Embodiment Construction

[0026] An asphalt mixture modifier, the component distribution ratio of the modifier includes: polyethylene A: 60-90 parts; polyethylene B: 0-30 parts; antioxidant A: 0.1-0.6 parts; Agent B: 0.1~0.6 parts; weather resistance agent: 0.2~0.8 parts; lubricant A: 0.4~1.2 parts; lubricant B: 3~12 parts, toner 0.8 parts.

[0027] The polyethylene A and polyethylene B are secondary materials or scraps recycled from packaging film, agricultural film, plastic wrap or mulch film waste, wherein the specific gravity of the polyethylene A is 0.90-0.96, the melt index is 1-5, and the tensile strength is 0.90-0.96. Tensile strength ≥ 12, elongation ≥ 300, softening point ≥ 80; the specific gravity of polyethylene B is 0.90-0.96, melt index 1-5, tensile strength ≥ 12, elongation ≥ 100, softening point ≥ 65 ; The antioxidant is antioxidant A tris (2,4-di-tert-butylphenyl) phosphite or antioxidant B tetrakis[β-(3.5-di-tert-butyl-4-hydroxyphenyl) propane One or two mixtures of acid] pentaerythr...

The asphalt mixture modifying agent comprises components of 60 to 90 parts of polyethylene A, 0 to 30 parts of polyethylene B, 0.1 to 0.6 part of antioxidant A, 0.1 to 0.6 part of antioxidant B, 0.2 to 0.8 part of weather resistance agent, 0.4 to 1.2 parts of lubricant A, 3 to 12 parts of lubricant B and 0.8 part of toner.

Description

technical field [0001] The invention belongs to the technical field of materials, and in particular relates to an asphalt mixture modifier and a preparation method and application thereof. Background technique [0002] Asphalt has waterproof and anti-corrosion properties, and is currently widely used as paving materials and covering materials for roads. However, asphalt pavement often has cracks, which will directly affect the service life of the pavement. Due to the cracking of the asphalt pavement, the water on the road surface seeps into the base layer, and at the same time, under the pressure of driving, the base layer of the road surface is damaged, thereby destroying the road surface and forming potholes. Therefore, it is particularly important to modify the asphalt mixture to enhance the performance of the pavement. [0003] Asphalt pavement is various types of pavement paved by mixing road asphalt materials in mineral materials. The asphalt binder improves the abi...
