Relying on the maintenance project of National Highway 207,performance tests were conducted on raw materials for the crushed stone sealing layer and compatibility tests were performed for rubber asphalt.A composition ratio was proposed for the rubber asphalt material,and rubber asphalt meeting the technical specifications was prepared and applied in practical en-gineering.The results demonstrated that the rubber asphalt synchronous crushed stone sealing layer exhibited exceptional adhe-sion and excellent skid resistance.It effectively mitigated and absorbed stress induced by cracks in the base layer,thereby reduc-ing reflective crack occurrence in the surface layer.This significantly enhanced pavement integrity and extended road service life,making it suitable for widespread implementation in Xilingol League region.
