　　The comprehensive perfermance of three kinds of surface preparation systems of polyurea coatings for Beijing-Shanghai High-Speed Railway bridge concrete beams protection both in situ and in lab were studied in this paper.The pull-off test and visual inspection were used to determine the adhesion and coverage effect of the bughole of shot blasted concrete surface.Adhesion tests were conducted both in situ and in lab over a period of 1 year.
