THE CONSTRUCTION OF AN EXPERIMENTAL PRESTRESSED CONCRETE ROAD WITHOUT JOINTS /FRENCH/

AN EXPERIMENTAL PRESTRESSED CONCRETE ROAD WITH FIXED ABUTMENTS 440M LONG AND 6M WIDE WAS BUILT IN LIER. THE PURPOSE OF THEIS EXPERIMENT WAS TO SHOW THAT DEFECTS WHICH HAD OCCURRED DURING THE CONSTRUCTION OF PREVIOUS EXPERIMENTAL SECTIONS BUILT WITH THE SAME TYPE OF PRESTRESSED CONCRETE COULD BE PREVENTED. CONCRETE CONTAINING LIGHTWEIGHT AGGREGATES AND AGGREGATES WITH A LOW COEFFICIENT OF EXPANSION WAS USED. THIS RESULTED IN KEEPING STRESS VARIATION IN THE SURFACING, CAUSED BY TEMPERATURE CHANGES, AT A PERMISSIBLE LEVEL. THE FRESH CONCRETE WAS SUBJECTED TO HIGH TENSILE STRESSES IN ORDER TO ACCELERATE CREEP AND PREVENT ULTERIOR LOSS OF PRESTRESSING IN THE SURFACNG. DETAILS ARE GIVEN OF THE DESIGN AND CONSTRUCTION OF THE ROAD TOGETHER WITH EXPERIMENTAL RESULTS OBTAINED DURING THE FIRST 30 MONTHS. /CRIC/FESR/LCPC/RRL/
