REPORT ON A FIELD EXPERIMENT ON INTRODUCTION OF PLANES OF WEAKNESS IN CONCRETE SLABS

AN EXPERIMENT WAS CONDUCTED TO INVESTIGATE THE REGULATING OR CONTROL OF TRANSVERSE CRACKS IN REINFORCED AND PLAIN CONCRETE PAVEMENT SLABS. PLANES OF WEAKNESS WERE INTRODUCED INTO SLABS DURING CONSTRUCTION. AFTER THE CURING PERIOD IT WAS OBSERVED THAT AT EACH PLANE OF WEAKNESS THE SLAB HAD CRACKED AND THE CRACK RAN THROUGH TO THE SUBGRADE. THE EXPERIMENTAL ROAD IS FREE OF CRACKS OTHER THAN AT THE PLANES OF WEAKNESS.
