THE REINFORCEMENT OF OLD CONCRETE SURFACES BY RESURFACING

THE CONSTRUCTION OF 12-CM THICK CONCRETE BLANKETS AND DOWELLING OF THE CROSS-JOINTS USED IN THE FIRST TEST PROVED TO BE INSUFFICIENT. THRUST ANCHORS BETWEEN OLD AND NEW SURFACINGS WERE ALSO INADEQUATE. IN THE SECOND AND THIRD TEST SERIES, THE NEW SURFACINGS WERE REINFORCED WITH AT LEAST 15 CM THICKNESS WITH SPECIAL TREATMENT OF THE LONGITUDINAL AND TRANSVERSE JOINTS. THE THIRD TEST SECTION COVERED 8700 SQUARE METRES. IT WAS MADE IN 1963 AND SHOWED NO DEFECTS UNDER HEAVY TRAFFIC LOADS, APART FROM TWO TRANSVERSE CRACKS (ASSEMBLY FAULTS). THIS PROVES THAT EVEN OLD, HEAVILY CRACKED CONCRETE SURFACINGS CAN BE REINFORCED, WIDENED AND ADAPTED TO MODERN TRAFFIC CONDITIONS. /RRL/
