Problems solved by technology

[0012] However, in the above-mentioned road patching materials, it is generally difficult to balance strength and crack resistance at the same time. Generally, in order to obtain high strength, it is necessary to make the patched area have high hardness, resulting in cracks. Therefore, how to develop a material that can balance strength and crack resistance? Crack-resistant road repair materials are becoming more desirable

Embodiment 1

[0033] The road repair material is prepared from tailings, cement, modified rubber and rubber particles, based on the total weight of the road repair material, the content of tailings is 55%, the content of cement is 34%, and the content of modified rubber is 10% , the content of modified rubber particles is 1%. The tailings are rare earth tailings (obtained from Tangshan Iron and Steel Concentrator), and the cement is a mixture of Portland cement and sulphoaluminate cement (both obtained from Hebei Tangshan Yandong Cement Company) with a weight ratio of 1:1 , and added calcium chloride accounting for 1.5% of the total weight of cement. The modified glue is polyurethane modified by nanoporous silica (from Zhejiang Hangzhou Wanjing New Material Co., Ltd.). The modified rubber particles are mixed with 5% epoxy resin and 0.1% polyether polyol glycidyl ether based on the total weight of the rubber particles, and the rubber particles are from waste tires.

Embodiment 2

[0035] (1) Pretreatment of the road repair material obtained according to Example 1: the road repair material is mixed with a solvent in a weight ratio of 3:1 to obtain a pre-repair material, and the solvent is water and ethanol in a 4:1 weight ratio mixture;

[0036] (2) Clean up road cracks or potholes: Use mechanical or manual methods to clean up road cracks or potholes until the concrete stabilization layer is exposed; among them, small cracks and narrow potholes need to be cleaned manually, and the loose concrete structure at the edge of the cracks needs to be completely removed. Clean up debris and engineering waste until the concrete stabilization layer is seen, use a high-power blower to thoroughly remove dust and sundries in the repaired area, and paint emulsified asphalt with a solid content of 50% in the repaired area, and wait until it is completely demulsified Carry out the direct pouring of the following pre-repair materials;

[0037] (3) Repair road cracks or p...

Abstract

The invention relates to a road patching material with favorable elasticity and abrasion resistance and application thereof. The road patching material comprises the following components in percentage by weight: 30-60% of tailing, 20-40% of cement, 5-30% of modified adhesive and 0.5-10% of rubber granule. The road patching material has the advantages of favorable abrasion resistance and favorable elasticity.

Description

technical field [0001] The invention relates to a road patching material with good elasticity and wear resistance and its application, in particular to a road patching material with good wear resistance and good elasticity and its application. technical background [0002] In recent decades, the domestic cement concrete pavement business has developed rapidly. By 2013, the mileage of cement concrete pavement in my country reached 1.2 million kilometers. With the rapid development of my country's economic strength, the traffic volume of roads is also increasing rapidly. The requirements for the quality of the structure are also higher. Cement concrete pavement has the incomparable advantages of asphalt pavement, such as high strength, high rigidity, strong bearing capacity, good stability, and good durability. However, in the face of the increasing road pressure, many roads are damaged due to overwhelm, but there are also disadvantages such as complicated maintenance, long se...
