AN ELEVEN-YEAR STUDY OF THE EXPANSION AND CONTRACTION OF A SECTION OF CONCRETE PAVEMENT

MEASUREMENTS ARE REPORTED OVER AN 11-YEAR PERIOD OF EXPANSION AND CONTRACTION OF A SECTON OF CONCRETE PAVEMENT BUILT IN 1934. THREE SETS OF MEASUREMENTS WERE TAKEN: (1) OPENING AND CLOSING OF THE JOINTS, (2) EXPANSION AND CONTRACTION OF A 20-IN. SECTION OF THE SLAB AT FOUR INTERIOR LOCATIONS, (3) CREEP OF THE PAVEMENT AT TWO POINTS. AIR AND SLAB TEMPERATURES WERE MEASURED. DURING THE FIRST 2 YEARS READINGS WERE TAKEN MONTHLY; SINCE THEN ONCE OR TWICE A YEAR. MEASUREMENT OF MOVEMENT AT THE JOINTS HAS SHOWN A PROGRESSIVE CLOSING OF THE JOINTS DURING THE 11-YEAR PERIOD. MEASUREMENT OF GROWTH BETWEEN 20-IN. GAGE POINTS SUPPORT THE THEORY THAT GROWTH DUE TO CHEMICAL AND PHYSICAL CHANGES IS AN IMPORTANT FACTOR IN CONCRETE PAVEMENT BEHAVIOR. ALTHOUGH A TENDENCY TO CREEP DOWNHILL WAS OBSERVED, THE AMOUNT WAS SO SMALL THAT IT IS NOT THOUGHT TO BE A FACTOR IN THE OBSERVED GROWTH OF THE CONCRETE. /AUTHOR/
