preparation example 1

[0030] Mix 20Kg of methyl methacrylate, 10Kg of brominated epoxy resin, 5Kg of nano-carbon powder, and 5Kg of sodium silicate at 120°C and add them to 20Kg of rubber oil. After stirring and heating to 150°C, the pressure is 2.0Mpa Under the condition of keeping warm for 2 hours, the binding agent is obtained.

preparation example 2

[0032] Mix 40Kg of methyl methacrylate, 15Kg of brominated epoxy resin, 8Kg of nano-carbon powder, and 8Kg of sodium silicate at 125°C and add them to 35Kg of rubber oil. After stirring and heating to 155°C, the pressure is 2.25Mpa Under the condition of keeping warm for 3 hours, the binding agent is obtained.

preparation example 3

[0034]Mix 60Kg of methyl methacrylate, 20Kg of brominated epoxy resin, 10Kg of nano-carbon powder, and 10Kg of sodium silicate at 130°C and add them to 50Kg of rubber oil. After stirring and heating to 160°C, the pressure is 2.5Mpa Under the condition of keeping warm for 4 hours, the binding agent is obtained.

[0035] Preparation Example 1 of High Viscosity Modified Asphalt

[0036] Heat 100Kg of base asphalt to 175°C, add 15Kg of styrene-isoprene-styrene block copolymer and 10Kg of polybutylene-terephthalate-polyether glycol block polymer, and heat at 175°C Swell at 190°C for 0.5 hours, then heat up to 185°C, then add 3Kg of binder and 0.05Kg of sulfur powder provided by the binder preparation example 1, control the temperature at 190°C and stir for 3 hours, then add 3Kg of sulfur powder after lowering the temperature to 180°C Phenyl dipropylene glycol diphosphite, that is, high-viscosity modified asphalt.

Abstract

The invention discloses an ultra-thin wearing layer asphalt mixture and a preparation method thereof, and belongs to the field of building materials for road engineering. The ultra-thin wearing layerasphalt mixture is prepared from the following raw materials in parts by weight: 100 parts of aggregate, 7-8 parts of high-viscosity modified asphalt, 2-4 parts of mineral powder, 3-5 parts of carbonblack, 1-3 parts of a curing agent, 3-5 parts of a compound stabilizer, and 7-12 parts of phenolic resin. After the ultra-thin wearing layer asphalt mixture is paved, a formed road ultra-thin wearinglayer is capable of solving problems in preventability maintenance that an anti-rutting property and a mechanical property are improved, and has the advantages of good skid resistance, abrasion resistance and ultralong durability.

Description

technical field [0001] The invention relates to the field of building materials for road engineering, more specifically, it relates to an ultra-thin wearing layer asphalt mixture and a preparation method thereof. Background technique [0002] In recent years, our country has been strengthening the management of various engineering constructions, especially the rapid development of road construction, which has greatly increased the pace of economic leaps. With the rapid development of the economy, the road traffic industry has gained huge With the development of the country, the country's requirements for road construction have also increased accordingly, and the purpose of promoting safety, beauty, and durability has been introduced to make the greatest guarantee for traffic safety. However, after many years of operation, many existing road surfaces have some slight diseases and surface function decline, so the maintenance of roads is extremely important. [0003] Ultra-thi...
