Abstract

The invention relates to an asphalt pavement net-shaped crack treatment regeneration sealing layer material and a preparation method thereof. The asphalt pavement net-shaped crack treatment regeneration sealing layer material is characterized by being composed of the raw materials in parts by weight: 70-100 parts of a composite emulsion and 200-400 parts of a fine aggregate; the composite emulsion is prepared by mixing the raw materials in pars by weight: 20-50 parts of an inorganic solution and 200-600 parts of an organic emulsion; the inorganic solution is an acidic silicon solution or a neutral silicon solution, the silica content is 10-30% (mass), the pH value is 3-7, the sodium oxide content is less than 0.5% (mass), and the average particle size is 10-20 nm; the organic emulsion comprises the raw materials by weight: 100 parts of a regeneration agent emulsion and 100-500 parts of modified emulsified asphalt. The asphalt pavement net-shaped crack treatment regeneration sealing layer material has strong permeability, plays good seam-sealing and waterproof roles in cracks, and has remarkable regeneration and reduction improvement effects on aged asphalt.

Description

technical field [0001] The invention relates to a regenerated sealing layer material for treating asphalt pavement network cracks and a preparation method thereof, which are widely used in preventive maintenance of asphalt pavement, repair of cracks in asphalt pavement, waterproof and anti-slip of asphalt pavement, prolonging the service life of asphalt pavement, and the like. Background technique [0002] Asphalt pavement is widely used in high-grade highways, provincial national highways and municipal roads in my country due to its many advantages such as comfortable driving, low vibration, low noise, wear resistance, no dust and easy cleaning, short construction period, easy maintenance and repair, and renewable utilization. use. However, due to the long-term exposure of the asphalt pavement to the atmospheric environment, and the long-term combined action of traffic load, ultraviolet rays and water, the asphalt is aging, and the macroscopic manifestations are cracks, loos...
