INVESTIGATIONAL CONCRETE PAVEMENT IN OREGON

THE PROGRAM IS DESIGNED TO FURNISH INFORMATION CONCERNING THE NECESSITY FOR THE SPACING, THE ARRANGEMENT, AND THE TYPE OF TRANSVERSE JOINTS IN CONCRETE PAVEMENTS. IT WAS FOUND THAT THE DISTANCE BETWEEN EXPANSION JOINTS DOES NOT SEEM TO HAVE ANY GREAT EFFECT ON THE EXPANSION JOINT CLOSURE, AT LEAST WHEN THIS DISTANCE IS 120 FT. OR MORE. THE MOVEMENT AT ALL EXPANSION JOINTS IS GREATER DURING THE FIRST YEAR THAN IN SUCCEEDING YEARS BECAUSE OF THE ACTION OF THE CONTRACTION JOINTS, WHICH, HAVING ONCE OPENED, FUNCTION AS NARROW EXPANSION JOINTS. THE NONREINFORCED SLABS SHOWED A SLIGHT TENDENCY TO SHRINK WITH AGE, WHILE THE REINFORCED SLABS REMAIN AT APPROXIMATELY THEIR ORIGINAL LENGTH. MEASUREMENTS INDICATED THAT THE CONCRETE IN THIS EXPERIMENTAL PROJECT IS NOT SUBJECT TO THE VOLUME INCREASE WITH AGE NOTED IN MANY OTHER PAVEMENTS. SPALLING AT CONTRACTION JOINTS TOOK PLACE DUE TO DISPLACEMENT OF THE FELT STRIPS BY THE FINISHING MACHINE.
