WATERPROOFING OF CONCRETE BRIDGE DECKS

IN SOME COUNTRIES AN UNEXPECTEDLY LARGE AMOUNT OF DETERIORATION HAS BEEN EXPERIENCED IN THE CONCRETE DECKS OF BRIDGES BUILT DURING THE PAST TWO DECADES. EXPERIENCE HAS SHOWN THAT UNDER HEAVY TRAFFIC, FULL EXPOSURE TO WEATHER, AND IN THE CORROSIVE ENVIRONMENT PRODUCED BY THE REGULAR APPLICATION OF DE-ICING SALT IN WINTER, THE STRUCTURAL CONCRETE NEEDS THE PROTECTION GIVEN BY AN EFFECTIVE WATERPROOFING LAYER. THE REPORT DISCUSSES THE REQUIREMENTS FOR AN EFFECTIVE WATERPROOFING LAYER, DESCRIBES THE SYSTEMS AVAILABLE (BITUMINOUS MATERIALS, PREFABRICATED SHEETING, AND THIN ADHESIVE MEMBRANES), REVIEWS THEIR USE IN VARIOUS COUNTRIES, AND EVALUATES CONCRETE SURFACINGS WITHOUT SPECIAL WATERPROOFING. IT THEN MAKES A CRITICAL APPRAISAL OF THESE SYSTEMS AND ENDS WITH CONCLUSIONS AND RECOMMENDATIONS FOR FURTHER RESEARCH. THE APPENDICES CONTAIN DETAILS OF TESTS AND SPECIFICATIONS FOR WATERPROOFING MATERIALS. /AUTHOR/
