Problems solved by technology

[0002] my country's road construction has entered a stage of rapid development, and as the asphalt pavement built in the early stage increases in service life, under the action of traffic load and various natural factors, the asphalt road gradually ages, and the asphalt road surface becomes rough due to oil loss. At the same time, there will be some slight cracks on the surface. At this time, the pavement surface aggregate will become loose, the water permeability coefficient will be too high, and the disease resistance will be low. If it is not treated in time, large pieces and cracks will appear soon. Aging, vehicle rolling and other reasons cause ruts, potholes, cracks and other phenomena on the road, resulting in reduced driving comfort, slow driving speed, damaged wheels, increased fuel consumption, etc., seriously affecting driving safety

Abstract

The invention relates to the field of petrochemical technology, in particular to an efficient restoration and restoration agent for asphalt pavement, including emulsified asphalt, high molecular polymer emulsion, photoinitiator, dispersant, microbial inducer, assembled aggregate, ultraviolet absorber, and residual water. Compared with the prior art, the high-efficiency reduction repairing agent for asphalt pavement of the present invention can be light-cured and cross-linked, can fully penetrate into the pores and tiny cracks of asphalt concrete, infiltrate, activate, repair and restore the aged asphalt, restore and enhance the viscosity of asphalt It also induces the generation of calcium carbonate crystals and aggregates to fill the cracks, realize self-repair, restore and enhance the waterproof performance of the pavement, play a comprehensive preventive maintenance role, reduce the investment in maintenance and repair, and the construction is simple. It can be used for rapid cosmetic renovation and beautification of various old asphalt pavements and various new asphalt pavements with poor oil and large voids due to construction quality problems.
