EXPERIMENTS WITH CONTINUOUS REINFORCEMENT IN CONCRETE PAVEMENT - A FIVE-YEAR HISTORY

RESULTS SHOW: (1) CHANGES IN PAVEMENT ELEVATION ARE SMALL AND NONUNIFORM AND DO NOT APPEAR TO AFFECT THE LENGTH CHANGES AND CRACK PATTERNS OF THE SECTIONS; (2) DAILY AND ANNUAL CHANGES IN SECTION LENGTH ARE NOT DIRECTLY PROPORTIONAL TO LENGTH OF SECTION; (3) THE MAGNITUDE OF THE RESTRAINT OFFERED BY THE SUBGRADE IS A FUNCTION OF THE TIME IN WHICH A GIVEN TEMPERATURE OR MOISTURE CHANGE OCCURS IN THE PAVEMENT; (4) MAXIMUM TENSILE STRESSES ORIGINATING FROM SUBGRADE RESTRAINT DEVELOP DURING LATE SUMMER AND FALL; (5) FREQUENCY OF CRACKING INCREASES WITH INCREASE IN SECTION LENGTH; (6) SURFACE APPEARANCE OF CRACKS IS A FUNCTION OF WIDTH, WHICH DECREASES WITH INCREASE IN AMOUNT OF LONGITUDINAL STEEL; AND (7) ALL OF THE CRACKS HAVE REMAINED SO TIGHTLY CLOSED THAT THEY HAVE LITTLE IF ANY STRUCTURAL SIGNIFICANCE. /AUTHOR/
