AN EXPERIMENTAL CONTINUOUSLY REINFORCED CONCRETE PAVEMENT IN ILLINOIS

EIGHT TEST SECTIONS, FOUR EACH UNIFORMLY 7 AND 8 INCHES THICK, WERE CONSTRUCTED. ONE SECTION OF EACH THICKNESS WAS REINFORCED LONGITUDINALLY WITH 0.3, 0.5, 0.7, AND 1.0 PERCENT STEEL, USING ROUND DEFORMED RAIL-STEEL BARS. TRANSVERSE REINFORCEMENT CONSISTS OF 3/8 IN. ROUND DEFORMED, INTERMEDIATE GRADE, BILLET STEEL BARS AT 12 AND 18 IN. CENTERS. THE PAVEMENT WAS BUILT DIRECTLY ON THE NATURAL SUBGRADE, ABOUT 90% POTENTIALLY PUMPING SOILS. HORIZONTAL AND VERTICAL MOVEMENTS AND TRANSVERSE CRACK WIDTHS WILL BE MEASURED AT VARIOUS LOCATIONS ALONG THE PAVEMENT. UNIT STRAINS IN LONGITUDINAL REINFORCING BARS ARE MEASURED BY SR-4 STRAIN GAGES, AND CONCRETE AND SUBGRADE TEMPERATURES, WITH THERMOCOUPLES. FINE TRANSVERSE CRACKS HAVE DEVELOPED. UNIT TENSILE STRESSES OF ALMOST 40,000 LB/SQ IN. HAVE BEEN MEASURED IN THE LONGITUDINAL REINFORCEMENT IN THE 7 IN. SECTION WITH .7 PERCENT STEEL. THE YIELD POINT OF THE STEEL IS APPROXIMATELY 70,000 LB./SQ. IN. /AUTHOR/
