JOINT CONSTRUCTION IN CONCRETE PAVEMENT

RESEARCH AND DESIGN ENGINEERS HAVE DEVELOPED A VAST STOREHOUSE OF INFORMATION ON PERFORMANCE OF VARIOUS TYPES OF JOINTS IN PORTLAND CEMENT CONCRETE PAVEMENTS. THE PERFORMANCE OF SUCH JOINTS DEPENDS TO A LARGE DEGREE ON THE TYPE AND QUALITY OF THEIR CONSTRUCTION. CARELESS CONSTRUCTION PRACTICES OR INCORRECT METHODS OF CONSTRUCTION RESULTING FROM A LACK OF KNOWLEDGE OF THE JOINT FUNCTION RESULTS IN PAVEMENTS WITH BELOW STANDARD RIDING CHARACTERISTICS AND MAINTENANCE PROBLEMS. CORRECT CONSTRUCTION PROCEDURES FOR VARIOUS JOINT TYPES ARE OUTLINED AND ILLUSTRATED. INSTALLATION OF DOWELS, TIEBARS AND EXPANSION JOINT FILLERS IS EXPLAINED. /AUTHOR/
