Embodiment 1

[0021] In step 1, the oil shale parent ore is crushed into fine particles by a pulverizer, and the diameter of the fine particles is 4 meshes, and solid particle fillers with a corresponding mesh number are obtained by screening.

[0022] In step 2, the above-mentioned fillers, additives and high-quality asphalt are in a ratio of parts by weight, filler: additive: high-quality asphalt=30:20:50, and the product is obtained after mixing at a temperature of 150 ° C; the product is in the form of "water-in-oil"; The additive is composed of 2 parts by weight of SBS, 2 parts by weight of EPS, 10 parts by weight of petroleum heavy liquid and 6 parts by weight of high-sulfur carbon.

[0023] In step 3, the above-mentioned product is used for patching the damaged road, or a layer of the above-mentioned product is re-paved on the damaged basic road surface as the coating of the road surface.

Embodiment 2

[0025] In the step 1, the oil shale is dry distillation oil shale waste residue. Other steps are the same as in Example 1.

Embodiment 3

[0027] In the step 1, the oil shale is small oil shale particles with a diameter of less than 6 mm that cannot be used in the dry distillation process. Other steps are the same as in Example 1.

Abstract

The present invention discloses an asphalt road and bridge antiskid maintenance material preparation method and applications of oil shale as a filler. The method comprises: crushing oil shale into fine particles through a crusher, screening to obtain a solid-state particle filler having corresponding mesh, and mixing the filler, an additive and high-quality asphalt at a suitable heating temperature to form a product, wherein the product is used for seam repair of the damaged road, or a layer of the asphalt road and bridge antiskid maintenance material coating is re-paved on the damaged base road surface. According to the present invention, the final product has advantages of skid resistance, wear resistance, large temperature difference resistance, water resistance, flat surface, no seam, low noise, and the like.

Description

technical field [0001] The invention belongs to the fields of chemical technology, resource recycling and road and bridge construction, and particularly relates to a preparation method of an asphalt road and bridge anti-skid maintenance material and the application of oil shale as a filler. Background technique [0002] With the sustained and rapid development of my country's economy, my country's road engineering has undergone earth-shaking changes. Asphalt pavement is even paved into country lanes. However, in some harsh climate areas, especially in northern China, due to the huge temperature difference between day and night and seasons, the asphalt shrinks repeatedly, resulting in the formation of a large number of vertical cracks, ruts and fatigue fractures on the asphalt pavement. Due to the huge area base of asphalt roads in my country, the cost of re-paving is extremely high. At present, the most effective way to solve this problem is to choose a patching asphalt wi...
