Abstract

The invention discloses a stable modified asphalt regenerant based on epoxy bio-oil and a preparation method of the stable modified asphalt regenerant. The stable modified asphalt regenerant is mainlyprepared by oxidizing, heating, stirring and mixing 70-80 parts of bio-reclaimed oil, 10-15 parts of a hot melt polymer, 0.5-1 part of a stable cross-linking agent, 4-8 parts of a fusion promoter and5-10 parts of a ductility improver. The stable modified asphalt regenerant has the advantages of economy, environmental friendliness, good regeneration effect, capability of effectively ensuring stable performance of the regenerated asphalt mixture and the like.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a stable modified asphalt regenerant based on epoxy bio-oil and a preparation method thereof. Background technique [0002] With the development of my country's economy and the development of the climate environment, the performance requirements of asphalt pavement materials are becoming more and more stringent. At the beginning of the 21st century, SBS modified asphalt has been widely used in the construction of high-grade asphalt pavement in my country because of its excellent road performance. Under the concept of economic, environmental protection and sustainable development in the new era, the use of old pavement milling materials is the only way for China's road development under the strategy of strengthening the country in transportation, and the aging SBS modified asphalt mixture with excellent performance is repeated The utilization is obviously beneficial to reduce th...
