Joint sealant material damage status of high speed railway ballastless track was introduced,the failure reason of asphalt joint sealant material was analyzed,and the harm of failure joint sealant material to structure durability of ballastless track was described. According to working environment and deformation features of ballastless track expansion joints,the performance requirements of repair materials was presented and silicone joint sealant material was developed independently. By combing with repair characteristics in the“skylight period”,a simple,fast and efficient repair process was proposed and silicone joint sealant material was used to repair failure joint sealant material of high speed railway during the same time,the repair effect of which is good.
