PERFORMANCE OF TRANSVERSE JOINT SUPPORTS IN RIGID PAVEMENTS

THIS REPORT PRESENTS FIELD PERFORMANCE OBSERVATIONS AND MEASUREMENTS AS WELL AS LABORATORY TEST RESULTS FOR DIFFERENT TRANSVERSE JOINT SUPPORTS IN FIVE NEW YORK STATE TEST PAVEMENTS. THE DEVICES TESTED INCLUDE PLAIN STEEL DOWELS, STAINLESS-STEEL-CLAD AND NICKEL- COATED DOWELS, AND TOW-COMPONENT MALLEABLE IRON SLEEVES. JOINTS WITHOUT MECHANICAL LOAD TRANSFER DEVICES, WHICH RELY INSTEAD ON AGGREGATE INTERLOCK AND SUBBASE SUPPORT, WERE ALSO OBSERVED. AFTER 10 TO 13 YEARS OF SERVICE, NONE OF THE TEST PAVEMENTS HAD DEVELOPED SIGNIFICANT JOINT FAULTING. ALTHOUGH MOST JOINTS WERE BEGINNING TO DISPLAY NON-UNIFORM OPENING, VERY FEW TRANSVERSE CRACKS HAD FORMED. MOST OF THESE CRACKS WERE OVER DRAINAGE STRUCTURES OR IN CUT-TO- FILL TRANSITIONS, AND COULD NOT BE ATTRIBUTED TO FAILURE OF THE JOINT SUPPORTS. PLAIN STEEL DOWELS AND MALLEABLE IRON SLEEVES CORRODED BADLY, RESULTING N SEVERE DETERIORATION AT SOME JOINTS. STAINLESS-STEEL- CLAD AND NICKEL-COATED DOWELS BOTH EFFECTIVELY RESISTED CORROSION. THE CLADDING AND COATING, HOWEVER, DID NOT EXTEND THE ENTIRE LENGTH OF THE DOWELS, AND IN A FEW CASES THE UNPROTECTED FIXED END CORRODED, RESULTING IN JOINT DETERIORATION. WHERE EXPANSION JOINTS WERE USED, THE CAPS ON THE SLIDING END OF THE DOWELS WERE PLAIN STEEL, AND THUS MAY HAVE CONTRIBUTED TO SOME JOINT DETERIORATION. /FHWA/
