Abstract

The invention provides a high-performance asphalt pavement regenerant and a preparation method thereof. The high-performance asphalt pavement regenerant is prepared from, by weight, 60-70 parts of anactivating component, 5-10 parts of a permeating component, 10-15 parts of a plasticizing component, 8-15 parts of a modifying component and 3-6 parts of an anti-aging component, and the sum of the weight parts of the raw materials is 100 parts. According to the invention, the synergistic combination of thermal stability substances is used as an activating component to replace the traditional aromatic hydrocarbon oil activating component, so that the thermal stability of the regenerant can be greatly improved, and the long-term aging performance of the regenerated mixture can be improved. Theselected surfactant enables the asphaltene association structure to be deassociated, and dissolution and dispersion of asphaltene are promoted. The preparation process is simple, raw materials are wide in source, starting from the asphalt aging mechanism, activation and performance blending of aging components are considered, and the prepared regenerant is excellent in pavement performance and wide in application prospect.

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...
