CORROSION ON REINFORCEMENT EXPERIMENTAL SELF-STRESSING CONCRETE PAVEMENT, ROUTE 2, GLASTONBURY

THIS IS AN ADDENDUM TO THE FINAL REPORT (JANUARY 1971). THE PAVEMENT WAS PLACED IN 1963 AND CONTAINED NO. 7 DEFORMED STEEL BARS IN THE TRANSVERSE DIRECTION AND 1/2-INCH DIAMETER 7-WIRE STRAND IN THE LONGITUDINAL DIRECTION. EIGHT CORES WERE TAKEN TO CUT BOTH THE TRANSVERSE AND LONGITUDINAL STEEL AND THE STEEL WAS EXAMINED FOR CORROSION. FOUR CORES WERE TAKEN AT TRANSVERSE CRACKS. ONE CORE SHOWED RUSTING OF A NO. 7 BAR WHERE THE TRANSVERSE CRACK WIDTH WAS GREAT ENOUGH TO ALLOW WATER TO PENETRATE. THE FOUR CORES THROUGH THE LONGITUDINAL TENDONS SHOWED SLIGHT ORANGE DISCOLORMENT OF THE STRAND WHICH MIGHT HAVE BEEN CAUSED BY MOISTURE AT THE TIME OF PAVING. MOVEMENTS AT VARIOUS CRACKS WERE TABULATED. IT IS ESTIMATED THAT THE PAVEMENT RECEIVES 26 TONS OF NACL PER YEAR PER 2 LANE MILE. /FHWA/
