High-performance asphalt pavement repair material

Abstract

A high-performance asphalt pavement repair material, which is made of the following raw materials in parts by weight: 25-35 parts of petroleum asphalt, 3-7 parts of micaceous iron oxide, 6-11 parts of butanol, and 7-9 parts of aluminum stearate , 2-4 parts of accelerator, 12-16 parts of rubber particles, 3-5 parts of hexaaminocaproic acid, 6-8 parts of polyvinyl alcohol, 0.4-1.2 parts of sodium aluminate, 0.5-1.2 parts of disodium octaborate tetrahydrate , 5-8 parts of fluorite powder, 4-8 parts of film-forming aids, 6-13 parts of acrylate, 5-7 parts of p-phenylenediamine, 4-8 parts of triethanolamine, 5-9 parts of sodium silicate, and 4 parts of sulfur ‑8 parts, polyamide 2‑4 parts. The beneficial effects of the present invention are: the high-performance asphalt pavement repair material of the present invention has very good viscosity and anti-aging properties, excellent repair performance, improves the anti-cracking ability of the material under low temperature conditions, and provides relatively high-demand road pavement. good guarantee.

Description

technical field [0001] The invention relates to a high-performance asphalt pavement patching material. Background technique [0002] With the development of highway construction in our country, asphalt concrete pavement has been used more and more in high-grade highway construction due to its many advantages, but the problem of cracking of asphalt pavement has not been well resolved so far. In the long-term use of asphalt pavement, it is inevitable that there will be problems such as easy aging, easy to cause reflective cracks on the road surface, and loose cracks that seriously affect the use function of the road surface. These road surface problems not only affect the overall appearance of the road, but also affect the normal traffic on the road, make the vehicle bumpy, affect the speed of the vehicle and the comfort of the passengers, and make the vehicle prone to mechanical failure and damage, and even cause traffic accidents. With the development of road construction a...

Problems solved by technology

In the long-term use of asphalt pavement, it is inevitable that there will be problems of easy aging, easy to cause reflective cracks on the road surface, and loose cracks that seriously affect the use function of the road surface

These road surface problems not only affect the overall appearance of the road, but also affect the normal traffic on the road, make the vehicle bumpy, affect the speed of the vehicle and the comfort of passengers, and make the vehicle prone to mechanical failure and damage, and even cause traffic accidents

With the development of road construction and transportation, various road damage phenomena are becoming more and more obvious. Among them, the problem of crack repair has attracted more and more attention, but the effect of crack repair is often not ideal.
