Wear-resistant and skid-resistant asphalt pavement treatment material and preparation method thereof

Abstract

The invention discloses a wear-resistant and skid-resistant asphalt pavement treatment material and a preparation method thereof. The wear-resistant asphalt is prepared from the following components in parts by weight: 40-60 parts of matrix asphalt, 30-40 parts of polyamide resin, 3-7 parts of a flexibilizer, 1-3 parts of a friction performance regulator, 1-3 parts of aramid fiber, 10-15 parts of modified silicon carbide powder, 2-7 parts of a silane coupling agent, 3-5 parts of epoxidized soybean oil, 2-7 parts of polydiethylsiloxane, 4-6 parts of wear-resistant carbon black, 2-5 parts of calcium sulfate whiskers and 7-12 parts of an emulsifier. The wear-resistant carbon black is added into the raw materials, so that the friction performance of a pavement can be improved, the calcium sulfate whiskers enable the treatment material to have good thermal stability, and the toughening agent can improve the toughness of the pavement when the pavement is rubbed by wheel pressure of an automobile and reduce cracks caused by temperature or stress.

Description

technical field [0001] The invention relates to the technical field of pavement materials, in particular to a wear-resistant and anti-skid asphalt pavement treatment material and a preparation method thereof. Background technique [0002] Asphalt pavement is widely used in my country's high-grade highways, provincial highways and municipal roads. Asphalt pavement is exposed to the atmospheric environment for a long time. As a binder, asphalt is a kind of polymer material, which is prone to aging under the combined action of traffic load, ultraviolet rays and water for a long time, resulting in cracks, looseness, water damage, tortoise, etc. on the asphalt pavement. Early diseases such as cracking and net cracking will reduce the service life of the road surface, easily cause driving bumps, and even cause safety accidents. For a long time, asphalt pavement maintenance has always adopted the maintenance method of "damage first and then repair", resulting in a passive maintena...

AI Technical Summary

Problems solved by technology

The asphalt pavement is exposed to the atmospheric environment for a long time. Asphalt as a cement is a polymer material, which is prone to aging under the combined action of traffic load, ultraviolet rays and water for a long time, resulting in cracks, looseness, water damage, and turtles on the asphalt pavement. Early diseases such as cracks and network cracks, and then reduce the service life of the road surface, easily cause driving bumps, and even cause safety accidents

For a long time, the asphalt pavement maintenance has been adopting the maintenance method of "damage first and then repair", which has resulted in a passive maintenance situation of "not treating minor illnesses, and repairing major illnesses". Limited maintenance funds are difficult to guarantee heavy maintenance work

[0003] However, the rapid development of traffic in the current society and the increase in car traffic have led to increased road loads, increased road noise, and sound pollution. In addition, long-term friction and wear, especially in high-temperature weather, can easily cause ground damage during high-speed friction of car tires. There will be an ignition point between the tire and the tire, forming a safety hazard and prone to traffic accidents
