JOINT SEAL MATERIALS - FINAL REPORT

THREE MAJOR EXPERIMENTAL FIELD INSTALLATIONS OF APPROXIMATELY 7 TYPES OF JOINT SEALING MATERIALS WERE USED TO COMPARE AND EVALUATE THE PRODUCTS OF NUMEROUS SEALANT MANUFACTURERS. THE SEALANTS WERE PLACED IN CONTRACTION JOINTS (3/8 X 2 IN.) WHICH WERE FORMED OVER THE SEPARATOR PLATES OF THE PROPRIETARY LOAD TRANSFER DEVICE ASSEMBLIES SPACED ON 61-FT. CENTERS. IN MOST CASES EACH MANUFACTURER FILLED IN AT LEAST 5 JOINTS WITH EACH PARTICULAR PRODUCT. THE JOINT MOVEMENTS, TEMPERATURES AND PERFORMANCE WERE OBSERVED FOR EACH JOINT UNTIL EITHER THE SEALANT FAILED OR CONCLUSIONS COULD BE DRAWN. EACH SEALANT IS DISCUSSED AND VARIOUS MODES OF FAILURE ARE ILLUSTRATED. CONCLUSIONS REACHED ARE THAT PREFORMED NEOPRENE GAVE EXCELLENT SERVICE WHEN PROPERLY INSTALLED. OF THE LIQUIDS, ONE COMPONENT POLYURETHANES, TWO COMPONENT POLYSULFIDE TARS AND TWO COMPONENT POLYSULFIDES WITH EXTENDERS PERFORMED THE BEST. /AUTHOR/ REFERENCES: HIGHWAY RESEARCH RECORD NO. 80, 1965.
