STRESS MEASUREMENTS IN CONCRETE PAVEMENTS
TESTS INDICATE THAT CONCRETE, WHEN REINFORCED WITH SMALL AMOUNTS OF STEEL, MAY BE EXTENDED MORE WITHOUT VISIBLE CRACKING THAN WHEN UNREINFORCED. THE EXTENSIBILITY OF DRY CONCRETE BEAMS WAS FOUND TO BE LESS THAN THAT OF WET SPECIMENS. DEFORMATION MEASUREMENTS IN EXISTING CONCRETE ROADS FURNISH AN EXCELLENT INDEX OF THE LOAD-CARRYING ABILITY OF THE SLAB. THE RECENT MEASUREMENTS CORROBORATE THE THICKENED EDGE DESIGN. TESTS IN COOK COUNTY, ILLINOIS INDICATE THAT A 9-7-9 SECTION IS SUITABLE FOR 8,750-POUND MAXIMUM WHEEL LOAD. IT IS INDICATED THAT, FOR ALL PRACTICAL PURPOSES THE STRESS PRODUCED IN CONCRETE PAVEMENTS IS DIRECTLY PROPORTIONAL TO THE WHEEL LOAD. WITHIN PRACTICAL MINIMUM LIMITS OF AXLE SPACING, THE INDIVIDUAL AXLE LOADS OF A SIX-WHEEL TRUCK MAY BE AS HEAVY AS IN THE CASE OF A FOUR-WHEEL TRUCK.
