BRIDGE DECK DETERIORATION IN COLORADO

This is an Interim Report which reviews the capability of the Department of Highways to detect bridge deck deterioration and to take remedial and deterrent action. Department personnel have observed FHWA demonstrations of, and gained experience in the use of, equipment and procedures to evaluate bridge decks. Decks have been repaired using a wide range of materials and processes, from limited patching with both common and unusual or experimental proprietary materials, to extensive removal and replacement of deck concrete. An expanded program of removal of damaged and/or contaminated deck material and replacement with latex modified concrete will be undertaken during the upcoming construction season. Placement of the same material on a new structure also will occur this year. Considerable laboratory and field testing of moisture barrier membranes has been done. Specifications covering fabrication and application of membranes have been published and refined. An extensive retesting program is being carried out to check the continued effectiveness of waterproofing membranes and installation technqiues. Research continues in an effort to bring forth economical methods for prevention of bridge deck deterioration and repair of decks already damaged. /FHWA/
