SUMMARY OF OBSERVATIONS AND REPAIRS ON STRUCTURES OPENED TO TRAFFIC

SYNTHESE DES CONSTATATIONS ET DES REPARATIONS SUR OUVRAGES EN SERVICE

SOME DEFECTS OBSERVED IN STRUCTURES OPENED TO TRAFFIC BY REGIONAL LABORATORY INSPECTION TEAMS SHOW SYSTEMATIC CHARACTERISTICS. THE OBJECTIVE OF THIS RESEARCH IS TO SUMMARIZE THOSE DEFECTS. FOLLOWING EXPERIMENTS IN 1978 WITH WORKING TECHNIQUES DEFINED IN 1977, IT IS PLANNED IN 1979: - TO CONTINUE THE APPLICATION TO STRUCTURES OF THE PSDP TYPE; - TO EXTEND IT TO STRUCTURES OF THE PSDM TYPE AND TO PROBLEMS OF THE EFFECTS OF EMBANKMENTS ADJOINING SKEWED FRAMES.
