CONCRETE PAVEMENT WITH CONTINUOUS REINFORCEMENT AND ELASTIC JOINTS-TEST ROADS, JOINT INSERTS AND DESIGN

FROM STUDIES OF THE STRUCTURAL BEHAVIOR OF CONTINUOUSLY REINFORCED PAVEMENTS AND AN ANALYSIS OF THE TECHNICAL AND PRACTICAL DIFFICULTIES ENCOUNTERED IN CONVENTIONAL JOINED PAVEMENTS THE AUTHPR HAS DESIGNED A NEW TYPE OF PAVEMENT: A CONTINUOUSLY REINFORCED CONCRETE PAVEMENT WITH ELASTIC JOINTS. THE PAVEMENT IS CENTRALLY REINFORCED WITH CONTINUOUS ROUND BARS. CRACK INITIATORS, E.G., FIBER BOARD STRIPS, ARE SPACED AT SUITABLE INTERVALS. UNDER THE JOINTS, THE CONTINUOUS PLAIN ROUND BARS ARE DE-BONDED WITH CUT-BACK BITUMEN, OVER SUCH A LENGTH THAT WHEN A MOVEMENT OCCURS THE TENSILE YIELD POINT IS NOT EXCEEDED, THE STRESSES IN THE CONCRETE ARE REASONABLE, AND THE JOINT OPENINGS RESTRAINED. THIS TYPE OF PAVEMENT SEEMS TO BE THE MOST ECONOMICAL OF PRESENTLY AVAILABLE DESIGNS WITH REGARD TO BOTH CONSTRUCTION AND MAINTENANCE.
