RIGID TYPE PAVEMENT JOINTS AND JOINT SPACING

THE SHRINKAGE OF CONCRETE IN SETTING WILL PROVIDE SUFFICIENT EXPANSION SPACE FOR PAVEMENTS CONSTRUCTED DURING NORMAL SUMMER CONDITIONS. IF PLANES OF WEAKNESS ARE CONSTRUCTED AT APPROXIMATELY 15 FT. INTERVALS, A CERTAIN DEGREE OF DOWELLING ACROSS THE JOINTS WILL BE MAINTAINED. THE DIVISION OF CONCRETE BASES INTO SLABS 12 1/2 FT. LONG WILL PROVIDE DEFINITE CONTROL OF CRACKING IN SHEET ASPHALT SURFACES; THE MOVEMENT AT ANY ONE JOINT BEING SO SLIGHT AS TO BE ABSORBED BY THE RESILIENCE OF THE BITUMINOUS SURFACE. THE CONSTRUCTION OF REASONABLY SHORT SLABS IS RECOMMENDED, AS WELL AS THE USE OF WELL DISTRIBUTED REINFORCEMENT, TIE BARS AT ALL CONSTRUCTION JOINTS AND LOAD TRANSFERS ACROSS ALL TRANSVERSE EXPANSION AND CONTRACTION JOINTS. /AUTHOR/
