Abstract

The invention provides a high-performance asphalt pavement rejuvenator and a preparation method thereof. It is made of the following raw materials in parts by weight: 60-70 parts of the activation component, 5-10 parts of the permeation component, and 5-10 parts of the plasticizing component 10-15 parts, 8-15 parts of modified components, 3-6 parts of anti-aging components, and the sum of parts by weight of raw materials is 100 parts. The present invention selects a synergistic combination of heat-stable substances as the activating component to replace the traditional aromatic oil activating component, which can not only greatly improve the thermal stability of the regenerant, but also improve the long-term aging performance of the regenerated mixture. The selected surfactant can disassociate the association structure of asphaltene and promote the dissolution and dispersion of asphaltene. The preparation process of the invention is simple, the source of raw materials is wide, starting from the mechanism of asphalt aging, and considering the activation and performance coordination of aging components, the prepared rejuvenator has excellent road performance and broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of road engineering and relates to a regeneration agent, in particular to a high-performance asphalt pavement regeneration agent and a preparation method thereof. Background technique [0002] Facing the huge maintenance and repair market, a large amount of asphalt mixture waste will be generated every year in the maintenance of pavement. These discarded old asphalt mixture not only occupy a large amount of land, but also cause ecological environment pollution. At the same time, a large amount of new asphalt mixture needs to be produced to replace the discarded old asphalt mixture, which consumes a lot of resources and construction funds. Moreover, with the gradual popularization of the concept of environmental protection, the mining of high-quality aggregates is becoming more and more difficult. Therefore, the recycling of old asphalt pavement materials has significant economic, social and environmental be...
