PRESSURE RELIEF JOINTS FOR RIGID PAVEMENTS

THIS REPORT WAS PREPARED TO FOCUS ATTENTION ON DAMAGE OCCURRING TO SOME HIGHWAY BRIDGES AS A RESULT OF PRESSURE EXERTED BY ADJACENT RIGID PAVEMENT SLABS. THE REPORT ILLUSTRATES SOME OF THE CONDITIONS PRECEDING SERIOUS BRIDGE DAMAGE, AND DESCRIBES SEVERAL TRANSVERSE PAVEMENT JOINTS THAT HAVE BEEN USED TO PREVENT SUCH DAMAGE. THE PRIMARY CAUSE OF THIS FORM OF DAMAGE IS ATTRIBUTED TO FILLING OF TRANSVERSE PAVEMENT JOINTS WITH INCOMPRESSIBLE MATERIALS, WHICH THUS PREVENT THEM FROM CLOSING FULLY IN WARM WEATHER. OF THE SEVERAL RELIEF JOINT TYPES DESCRIBED, ONE, DEVELOPED BY THE IOWA STATE HIGHWAY COMMISSION, IS RECOMMENDED, WHICH CONSISTS OF SAWING AND REMOVING 4 IN. OF PAVEMENT AND FILLING THE SPACE WITH A RIGID, FOAMED URETHANE. THIS IS A CORRECTIVE RATHER THAN A PREVENTIVE MEASURE TO BE USED WITH DISCRETION. IT IS NO SUBSTITUTE FOR GOOD JOINT MAINTENANCE AND MAY RESULT IN LOSS OF LOAD TRANSFER AND IN OPENING OF ADJACENT JOINTS WITH ATTENDANT PROBLEMS AT THOSE SITES. CONDITIONS WARRANTING THE JOINT'S USE ARE DESCRIBED. /AUTHOR/
