Title: CATHODIC PROTECTION OF CONTINUOUSLY REINFORCED CONCRETE PAVEMENT
Accession Number: 00369286
Record Type: Component
Availability: Find a library where document is available Abstract: Some sections of continuously reinforced concrete pavement (CRCP) in Minnesota are experiencing a spalling-type deterioration caused by corrosion of the reinforcing steel. In an attempt to develop a method of stopping this corrosion, a cathodic protection system was designed and installed along a 1000-ft. section of Interstate CRCP just north of St. Paul. High silicone chromium iron alloy anodes energized by a constant-current output rectifier were placed at the edge of the 10-ft. bituminous shoulder at 50-ft intervals. On half the project, the anodes were buried in a trench that was backfilled with coke breeze. On the other half of the project, canisters containing the anodes packed in coke breeze were placed in post holes and backfilled with additional coke breeze. It appears that both types of installation are providing at least partial cathodic protection to the pavement. (Author)
