PUMPING OF CONCRETE PAVEMENTS IN NEW JERSEY, CORRECTIVE MEASURES AND FUTURE DESIGNS

TESTS SHOWED THAT A JOINT COMPRISING TWELVE 2-INCH DEPTH CHANNEL DOWELS, 20 INCHES LONG PREVENTED FAULTING ENTIRELY AND MATERIALLY RETARDED PUMPING. A SURVEY OF PAVEMENTS LAID ON GRANULAR SUBBASE MATERALS SHOWED THAT THEIR USE WOULD MINIMIZE PUMPING, REDUCE DAMAGE DUE TO FROST ACTION, AND INCREASE LOAD BEARING CAPACITY. WOOD AS A JOINT FILLER IS VALUABLE BECAUSE IT WILL NOT EXTRUDE LIKE CONVENTIONAL FILLERS, AND IT WILL PROBABLY RETAIN AMPLE SWELLING RANGE AND RESILIENCY TO PREVENT RAPTURE. SINCE RUSTED DOWELS INDUCE EXCESSIVE TENSION IN OLDER PAVEMENTS, PLANS ARE BEING MADE TO PROVIDE CORROSION-RESISTANCE DOWELS.
