PERFORMANCE OF TRANSVERSE JOINT SUPPORTS IN CONCRETE PAVEMENT

TRANSVERSE JOINT SUPPORT SYSTEMS INCORPORATED IN CONCRETE PAVEMENTS WERE INVESTIGATED. THE BASIC TYPES OF DEVICES STUDIED WERE THE 1 1/4 X 18 INCH LONG ROUND DOWEL, THE SPADE, A SINGLE COMPONENT MALLEABLE IRON DEVICE CALLED THE HINGE, AND THE TWO-COMPONENT OR ARTICULATED DEVICE. JOINT FAULTING MEASUREMENTS WERE ON THREE PAVEMENTS CONTAINING TWO OR MORE TYPES OF JOINT SUPPORTS. SUPPLEMENTARY STUDIES INCLUDED A STATISTICAL ANALYSIS OF JOINT FAULTING AND PAVEMENT CRACKING DATA CONTAINED IN THE TALLAMY REPORT ON THE NEW YORK STATE THRUWAY, ANALYSIS OF HORIZONTAL JOINT MOVEMENT MEASUREMENTS ON A PAVEMENT CONTAINING PLAIN AND COATED DOWELS, AND A SMALL LABORATORY TESTING PROGRAM CONDUCTED ON STANDARD DOWELS REMOVED FROM TWO PAVEMENTS. IT WAS CONCLUDED THAT STANDARD SIZED DOWELS AND TWO-COMPONENT MALLEABLE IRON DEVICES WERE EQUALLY EFFECTIVE IN LIMITING JOINT FAULTING, BUT THAT THE DOWELS PRODUCED SIGNIFICANTLY MORE MIDSLAB CRACKING BY RESTRAINING JOINT MOVEMENT. OF THE OTHER DEVICES STUDIED, THE MALLEABLE IRON HINGE PERFORMED ACCEPTABLY AND MAY WARRANT FURTHER INVESTIGATION. /AUTHOR/
