CLEANING AND RESEALING OF CONCRETE PAVEMENT JOINTS BY CONTRACT

THE PROPER MAINTENANCE OF THE SEAL IN THE JOINTS OF CONCRETE PAVEMENT HAS FOR SOME TIME BEEN A MAJOR PROBLEM IN OUR MAINTENANCE OPERATIONS. WITH THE EVER INCREASING SCOPE OF MAINTENANCE WORK THE DEPARTMENT HAS NOT BEEN ABLE TO KEEP UP WITH THE PROPER MAINTENANCE OF THE JOINTS. A SMALL AMOUNT OF EXPERIMENTAL CLEANING AND RESEALING OF JOINTS WITH A HOT RUBBER ASPHALT COMPOUND WAS DONE BY THE MAINTENANCE FORCES AT AN AVERAGE COST OF $0.253 PER LINEAR FOOT. IT WAS FELT THAT THIS COST WOULD BE CONSIDERABLY REDUCED IF THE WORK WERE DONE ON A LARGER SCALE AND BY CONTRACT. A PROGRAM WAS SET UP AND TWO PROJECTS TOTALING 29 MILES IN LENGTH WERE COMPLETED BY CONTRACT. THE AVERAGE FINAL UNIT COSTS FOR CLEANING AND RESEALING JOINTS AND CRACKS WERE $0.099 PER LINEAR FOOT ON ONE CONTRACT AND $0.112 PER LINEAR FOOT ON THE SECOND CONTRACT. THESE UNIT PRICES INCLUDE ONLY THE COST OF CLEANING AND APPLYING THE SEAL PLUS THE COST OF THE MATERIAL. IT IS ESTIMATED THAT $0.02 PER LINEAR FOOT WILL COVER THE COST OF TRAFFIC CONTROL AND PROTECTION. IN ADDITION TO THE RESEALING OF THE JOINTS, A TWO-INCH RELIEF JOINT WAS CUT IN THE PAVEMENT EVERY 18000 FEET TO PROVIDE EXPANSION SPACE IN HOT WEATHER AND TO REDUCE THE NUMBER OF YEARLY BLOWUPS NOW OCCURRING IN OUR PAVEMENTS TWENTY YEARS OF AGE OR OLDER. THE RELIEF JOINTS WERE FORMED BY SAWING THROUGH THE 8-INCH PAVEMENT ON A LINE PARALLEL TO AND 2 INCHES FROM ONE OF THE JOINT FACES. THIS 2-INCH OPENING WAS FILLED WITH SEVERAL PIECES OF 1-INCH PREMOULDED FIBER BOARD UP TO WITHIN 1 1/2 INCHES FROM THE SURFACE OF THE CONCRETE. THE JOINT WAS THEN SEALED WITH HOT RUBBER ASPHALT COMPOUND OF THE SAME TYPE USED IN RESEALING THE PAVEMENT JOINTS. IT IS QUITE APPARENT FROM THE OBSERVED CONDITION OF OLDER PAVEMENT JOINTS IN CONNECTICUT THAT THE CLEANING AND RESEALING OF JOINTS IS WELL WORTHWHILE. IN VIEW OF THE FACT THAT THE OLDER JOINTS ARE BY NOW QUITE FILLED WITH FOREIGN MATERIAL AND THE PRESENT METHOD DOES NOT CLEAN THE FULL DEPTH OF JOINT, IT HAS BEEN DEEMED ADVISABLE TO REARRANGE THE SCHEDULE OF JOINT SEALING. IN THE FUTURE, THIS CORRECTIVE WORK WILL BE DONE ON PAVEMENTS UP TO FIVE YEARS OF AGE FIRST AND THEN GRADUALLY PROGRESS TO THE OLDER PAVEMENTS, THUS PREVENTING THE NEWER PAVEMENTS FROM APPROACHING THE CONDITION OF DISTRESS NOW SO PREVALENT ON THE OLDER ROADS. /AUTHOR/
