SELF-PROPELLED MACHINES FOR UNFORMED CONCRETE SLAB CONSTRUCTION IN ILLINOIS

A PROGRAM OF REHABILITATING OLD EXISTING 18-FOOT CONCRETE PAVEMENTS BY WIDENING THE SLABS LED TO THE DEVELOPMENT OF A MACHINE TO CONSTRUCT ONE LANE OF CONCRETE PAVEMENT WITHOUT FORMS. ONE OF THE LATEST DEVELOPMENTS IS AN ENTIRELY DIFFERENT TYPE OF CONCRETE PAVER OR FINISHING MACHINE. THIS EQUIPMENT PLACES CONCRETE BASE COURSES WITHOUT THE USE OF THE CONVENTIONAL SIDE FORMS. THE MACHINES EMPLOY THE USE OF SLIP FORMS WHICH ELIMINATE THE COSTLY OPERATION OF HANDLING AND SETTING FORMS. THE DEVELOPMENT OF THESE MACHINES IS DESCRIBED AND THE RESULTS WHICH HAVE BEEN OBTAINED WITH THEIR USE DEMONSTRATED. THE MACHINES ARE CAPABLE OF LAYING FULL-WIDTH SLABS WHICH ARE UNIFORM IN THICKNESS AND HAVE STRAIGHT EDGE ALIGNMENT. THE EDGES STAND VERTICALLY WITH VERY LITTLE SLUMPING. COMPRESSION TESTS MADE ON CORES REMOVED FROM THE BASE COURSE INDICATE STRENGTHS COMPARABLE TO CONCRETE PLACED BY OTHER METHODS.
