AN EXPERIMENT IN PAVEMENT SLAB DESIGN (REPORT SUPPLEMENT - FINAL)

THE EXPERIMENTATION INCLUDED THE INTRODUCTION OF A NUMBER OF SPECIAL FEATURES AN A REGULARLY SCHEDULED PORTLAND CEMENT CONCRETE PAVING PROJECT IN 1952, AND OBSERVATIONS OF THE FEATURES OVER A SUBSEQUENT 13-YEAR PERIOD. THE EXPERIMENTATION INCLUDED SECTIONS OF 9 AND 10 INCH THICKNESSES OF BOTH REINFORCED AND NON-REINFORCED PAVEMENT (WITH AND WITHOUT TRANSVERSE JOINTS). VARIOUS METHODS OF JOINT FORMING AND SEALING WERE EVALUATED ON DOWELED AND UNDOWELED JOINTS SPACED AT 20 FEET AND 100 FEET INTERVALS. CRACKING, SPALLING, FAULTING, RIDING QUALITY, PUMPING, JOINT MOVEMENTS, AND SEALER LIFE WERE OBSERVED AND RELATED TO THE TRAFFIC. THE PRACTICE OF SAWING TRANSVERSE JOINTS AT UP TO 100-FEET INTERVALS WITHOUT EXCESSIVE PREMATURE CRACKING RESULTED FROM THIS PROJECT. /AUTHOR/
