TRANSVERSE JOINT CONSTRUCTION

TRANSVERSE JOINTS ARE CONSTRUCTED IN PORTLAND CEMENT PAVEMENTS TO RELIEVE INTERNAL STRESSES BY PERMITTING CONTRACTION AND EXPANSION OF PAVEMENT SLABS. ALTHOUGH MANY DIFFERENT METHODS HAVE BEEN USED TO CONSTRUCT THESE JOINTS THE METHODS CAN BE CLASSIFIED IN THREE GROUPS: HAND FORMING, INSERT FORMING, AND SAWING. THIS STUDY WAS UNDERTAKEN TO EVALUTE THE VARIOUS METHODS, NOT ONLY FROM A CONSTRUCTION STANDPOINT, BUT ALSO FOR LONG TERM PERFORMANCE OF THE JOINT. TO ACCOMPLISH THIS, OBSERVATIONS OF CONSTRUCTION METHODS AND SPALL SURVEYS WERE CONDUCTED THROUGHOUT NEW YORK STATE. DURING THE EARLY STAGES OF EVALUATION, IT WAS DETERMINED THAT CERTAIN VARIABLES SUCH AS, WEATHER DURING PAVING, SMALL MODIFICATIONS TO CONSTRUCTION METHODS, CLIMATE, AND TRAFFIC COULD INFLUENCE THE PERFORMANCE OF THE JOINTS. THEREFORE IN AN ATTEMPT TO EVALUATE JOINTS CONSTRUCTED BY VARIOUS METHODS, BUT WITH MANY OF THE VARIABLES CONTROLLED, A TEST AREA WAS CONSTRUCTED AT FISHKILL, NEW YORK, ON A SECTION OF INTERSTATE ROUTE 84. BASED ON THE DATA COLLECTED AND THE FIELD OBSERVATIONS THAT WERE MADE BOTH AT THE TEST SITE AND STATEWIDE, ADVANTAGES AND DISADVANTAGES OR PROBLEMS ASSOCIATED WITH EACH METHOD HAVE BEEN IDENTIFIED AND ARE DISCUSSED WITHIN THE REPORT. IN ADDITION, ELEVEN GENERAL CONCLUSIONS HAVE BEEN DRAWN WHICH CAN SERVE AS A GUIDE TO ONE DESIGNING OR EVALUATING A CONSTRUCTION METHOD. /AUTHOR/
