Embodiment 1

[0029] This embodiment provides a high modulus oil corrosion resistant asphalt mixture, which is composed of: 26 kg of limestone aggregates with a particle size of 10 to 15 mm, 38 kg of limestone aggregates with a particle size of 5 to 10 mm, and limestone with a particle size of 3 to 5 mm 13kg of aggregate, 21kg of limestone aggregate with a particle size of 0-3mm, 2kg of mineral powder with a particle size of 0-0.15mm, 0.5kg of high modulus modifier, 0.5kg of polyether modified polysiloxane, and 0.5kg of glass fiber , base asphalt 4.8kg.

[0030] Wherein, the high modulus modifier is composed of a modified matrix and additional light stabilizers, compatibilizers, antioxidants and oxidized polyethylene added to the modified matrix; in practical applications, each After the ingredients are mixed, a twin-screw extruder is used to melt and granulate to obtain a high modulus modifier;

[0031] in particular:

[0032] The modified matrix is ​​formed by mixing LLDPE, LDPE and SBS...

Embodiment 2

[0038] This embodiment provides a high-modulus oil-resistant asphalt mixture. Compared with Embodiment 1, the only difference is that the modified matrix is ​​formed by mixing LLDPE, LDPE and SBS at a mass ratio of 6.5:2:1.5. become.

Embodiment 3

[0040] This example provides a method for preparing a high-modulus oil-resistant asphalt mixture. The mixture described in Examples 1 and 2 can be prepared by this method, specifically:

[0041] (1) Add the aggregate, mineral powder and glass fiber to the agitator, and directly put the high modulus modifier and the anti-oil corrosion agent into the agitator during the dry mixing process, and mix evenly;

[0042] (2) Add base asphalt to the mixture obtained in step (1), and stir evenly to obtain the product.

Abstract

The invention relates to a high-modulus anti-oil-corrosion asphalt mixed material. The asphalt mixed material contains the following components: an aggregate with a particle size of 10mm-15mm, an aggregate with a particle size of 5mm-10mm, an aggregate with a particle size of 3mm-5mm, an aggregate with a particle size of 0-3mm, mineral powder with a particle size of 0-0.15mm, glass fiber, a high-modulus modifying agent, an anti-oil-corrosion agent and matrix asphalt. The invention simultaneously provides a preparation method of the high-modulus anti-oil-corrosion asphalt mixed material. The high-modulus anti-oil-corrosion asphalt mixed material has a relatively good anti-oil-corrosion effect and simultaneously has relatively high modulus, and a production process is simple; and the anti-oil-corrosion agent is used by virtue of a direct feeding method, and asphalt modifying equipment and other equipment are not additionally required in the construction, so that the construction is relatively convenient.

Description

technical field [0001] The invention relates to the field of road construction materials, and relates to a pavement pavement material and a preparation method thereof, in particular to a high modulus oil corrosion resistant asphalt mixture and a preparation method thereof. Background technique [0002] Asphalt pavement has good driving comfort and excellent performance, fast construction speed and convenient maintenance, so it has been widely used in road construction in our country. However, the rapid development of the logistics and freight industry has led to a sudden increase in traffic volume, and oil spills such as heavy-duty vehicles, vehicle failures, and traffic accidents have become increasingly serious. [0003] Asphalt is a complex polymer mixture, which is easily soluble in organic solvents such as gasoline and diesel in terms of chemical composition. The harmful oil pollution (mainly diesel and gasoline) leaked on the asphalt pavement dissolves the asphalt, wh...
