TRANSVERSE JOINT CONSTRUCTION METHODS RELATED TO PERFORMANCE

TRANSVERSE JOINTS ARE CONSTRUCTED IN RIGID PAVEMENTS TO RELIEVE INTERNAL STRESSES. THE MANY DIFFERENT METHODS THAT HAVE BEEN USED FOR THEIR CONSTRUCTION MAY BE CLASSIFIED IN THREE CATEGORIES: HAND-FORMING, INSERT-FORMING, AND SAWING. THE STUDY REPORTED WAS UNDERTAKEN TO EVALUATE THESE METHODS FROM THE STANDPOINTS OF BOTH CONSTRUCTION AND LONG-TERM PERFORMANCE. CONSTRUCTION WAS OBSERVED AND SPALLING SURVEYED AT SELECTED JOINTS THROUGHOUT THE STATE FOR OVER 10 YEARS. EARLY IN THIS PERIOD, IT WAS DETERMINED THAT CERTAIN VARIABLES COULD INFLUENCE JOINT PERFORMANCE -- WEATHER DURING PAVING, MINOR MODIFICATIONS TO CONSTRUCTION METHODS, VARYING CLIMATE DURING SERVICE, AND DIFFERING TRAFFIC CONDITIONS. THUS, TO EVALUATE JOINTS CONSTRUCTED BY VARIOUS METHODS, BUT WITH MANY OF THESE VARIABLES CONTROLLED, A TEST AREA WAS CONSTRUCTED AT FISHKILL ON A SECTION OF I 84. FROM THE DATA COLLECTED IN FIELD OBERVATIONS BOTH STATEWIDE AND AT FISHKILL, THE ADVANTAGES AND DISADVANTAGES ASSOCIATED WITH EACH METHOD WERE IDENTIFIED. ALTHOUGH NO ONE CONSTRUCTION METHOD RESULTED IN SPALL-FREE JOINTS, THOSE FORMED BY HAND OR WITH PLASTIC V-WEDGE INSERTS SEEMED TO PERFORM MORE SATISFACTORILY THAN THOSE CONSTRUCTED BY OTHER METHODS. IN ADDITION, ELEVEN GENERAL CONCLUSIONS ARE DRAWN THAT CAN SERVE AS GUIDELINES IN DEVISING OR EVALUATING A JOINT CONSTRUCTION METHOD.
