THERMAL EXPANSION AND CONTRACTION OF CONCRETE PAVEMENT IN UTAH

THE MOVEMENTS AT TRANSVERSE EXPANSION JOINTS AND SKEWED CONTRACTION JOINTS ARE BEING MONITORED ON A 9IN. THICK, SLIP FORMED, UNDOWELED, PLAIN CONCRETE PAVEMENT BUILT IN 1967. MEASUREMENTS ARE BEING TAKEN AT 4 BRIDGE ABUTMENT AREAS AND AT 4 OTHER CENTRAL AREAS IN A ONE MILE SECTION OF I-15 AT MIDVALE. MEASUREMENTS WERE OBTAINED OVER ONE 24 HOUR PERIOD IN THE AIR AND AT VARIOUS DEPTHS OF THE CONCRETE WHILE OTHER TEMPERATURES ARE MADE PERIODICALLY. MEASUREMENTS OF LOAD TRANSFER WERE ALSO MADE WITH A DYNAFLECT. THE OBJECT IS TO DETERMINE WHETHER THIS JOINTING SYSTEM IS SATISFACTORY IN ALLEVIATING DAMAGE CAUSED BY EXPANSION AND CONTRACTION THROUGH TEMERATURE, MOISTURE AND INTERNAL CHEMICAL CHANGES, VARYING CONDITIONS OF LOADING AND SUPPORT AND THE SHRINKAGE OF CONCRETE WITH AGE. THE RESULTS OF THIS FIRST YEAR OF TESTING SHOW THAT THESE IS NO UNCONTROLLED CRACKING AND NO EXCESSIVE JOINT MOVEMENT OR SLAB CREEPING. THE EFFECT OF POSSIBLE DAMAGE CAUSED BY SHRINKAGE DUE TO AGE WILL BE STUDIED ON A YEARLY BASIS AND REPORTED IN THE FINAL REPORT. /AUTHOR/
