Open joints of filling layer were the main defect type of CRTS Ⅱ slab-type ballastless track. Based on nationwide investigation for open joints of the filling layer for CRTS Ⅱ slab-type ballastless track,open joint categories,reasons behind and damage it might occur were analyzed. According to the structural characteristics of ballastless track,the proper remedy material and technology for open joints were studied. T he proposed scheme was put into application and the results are closely monitored for further improvement.
