Recently, the "rubber asphalt + domix" double composite modified asphalt pavement developed by Hunan Academy of transportation science has successfully completed the construction of 2km test road on the section of g5513 Changyi Expressway from east to West k65-k67 for the first time, which is a major breakthrough in the preventive maintenance technology of geothermal regeneration for domestic asphalt pavement. The research and design team of the maintenance and pavement engineering center of Hunan Academy of Transportation Sciences has developed a complete set of technology through a large number of indoor tests, including "multi unit heating + hot harrowing and milling combined technology + new solvent type warm mixing technology + unique new additive grading design + new rolling technology", which has solved many technical problems of double composite modified asphalt pavement in the process of geothermal regeneration paving And successfully completed the paving of the test section.
"Rubber asphalt + domix" double composite modified asphalt pavement has a very important role and far-reaching significance in the research and development of geothermal regeneration technology and the success of test road, which can greatly reduce the comprehensive cost of highway pavement maintenance, promote new technology and technology, and advocate green cycle high speed. Next, Hunan Academy of Transportation Sciences will carry out all-round tracking observation on the test road section, comprehensively evaluate the actual application effect of the technology on site, and promote it in the province's expressway.
