Application of Rubber Asphalt Stress Absorbing Layer in Asphalt Pavement Structure
The pavement structure layer types and thicknesses of the same route and adjacent construction sections in highway engineering examples are consistent.Among them,the SG1 section is equipped with a 10mm thick rubber asphalt stress absorbing layer between the surface layer and the base layer,while the SG2 section only has an asphalt lower sealing layer.After two years of consistent heavy traffic and repeated pressure,the SG1 section suffered from severe rutting damage,with no other cracks,potholes,or other defects;SG2 section shows normal slight ruts,but there are many transverse cracks with a spacing of about 30-40 meters,and no other defects.Based on this,an analysis and evaluation of the quality status of two road sections were conducted,and the advantages and disadvantages of two different structural designs were summarized.The applicability of the stress absorption layer design for some sections was analyzed,and optimization ideas for the design were also proposed,in order to provide reference for the subsequent design of road surface structures in highway engineering.
