CONSTRUCTION OF AN EXPERIMENTAL PRESTRESSED CONCRETE ROAD IN BELGIUM /IN DUTCH/

A PRESTRESSED CONCRETE ROAD, 440 M. IN LENGTH, WAS BUILT FOR THE STUDY OF CONSTRUCTIONAL PROBLEMS. PART OF THE COARSE AGGREGATE WAS REPLACED BY AN ARTIFICIAL LIGHT-WEIGHT MATERIAL IN ORDER TO REDUCE THE ELASTIC MODULUS OF THE CONCRETE AND THE VARIATIONS IN STRESS DUE TO CREEP AND SHRINKAGE. THE PAVEMENT WAS BUILT BETWEEN TWO REINFORCED CONCRETE ANCHORAGE SYSTEMS. THREE TRANSVERSE JOINTS WERE CONSTRUCTED: TWO OF THEM FOR PRETENSIONING BY MEANS OF SCREW-JACKS, THE THIRD ONE BEING A MEASURING JOINT. TWO LAYERS OF SHEET-PLASTIC WERE USED AS A SLIDING LAYER BETWEEN THE SLAB AND THE BASE. TEMPERATURE AND STRESS MEASUREMENTS WERE CARRIED OUT DURING CONSTRUCTION AND DURING FOUR YEARS AFTER CONSTRUCTION. /TRRL/
