Abstract

The invention relates to the technical field of asphalt pavement cold-recycling, and particularly discloses a normal temperature activation and regeneration agent for cold-recycling and a preparation method thereof. The normal temperature activation and regeneration agent for cold-recycling is mainly prepared from, by weight, 30-70 parts of a high-flash-point organic matter, 5-15 parts of high-molecular polymer, 5-15 parts of attenuation permeation agent and 20-60 parts of a dispersing agent. The problem that according to a traditional cold-recycling technology, reclaimed material old asphalt under normal temperature cannot be activated is solved, old asphalt and old mineral aggregates in reclaimed materials are recycled, the function, viscoelasticity, ductility and the like of aged asphalt can be recovered, and the comprehensive performance of the cold-recycled mixed material can be improved.

Description

[0001] (1) Technical field [0002] The invention relates to the technical field of asphalt pavement cold regeneration, in particular to a normal-temperature activated regeneration agent for cold regeneration and a preparation method thereof. [0003] (2) Background technology [0004] The existing asphalt pavement cold recycling technology, in the process of using recycled materials, mainly treats them as aggregates, adds new aggregates, and mixes them with new asphalt to become a new recycled mixture. The disadvantage of this conventional cold recycling technology is that the aged asphalt in the recycled material cannot fully play its role, and the water resistance and durability of the recycled mixture are not strong. [0005] (3) Contents of the invention [0006] In order to make up for the deficiencies of the prior art, the invention provides a normal temperature activated regenerant for cold regeneration which reduces the amount of asphalt and improves the compaction ef...
