TRAFFIC STRESSES PRODUCED IN CONCRETE ROADS

RESULTS ARE REPORTED OF VARIOUS STRAIN GAGE MEASUREMENTS ON DIFFERENT SECTIONS OF CONCRETE PAVEMENT AND ON DIFFERENT SUBGRADE MATERIALS. THE FOLLOWING INDICATIONS WERE RECEIVED FROM THE TESTS: (1) THE HIGHEST TENSILE STRESSES EXIST ALONG THE EDGES OF A SLAB OF UNIFORM THICKNESS, (2) HIGH TENSION ALSO EXISTS AT THE CORNERS ON THE TOP OF THE SLAB BUT THE VALUE OF THE TENSION IS NOT AS HIGH AS THAT ALONG THE EDGE, (3) AT AN UNSUPPORTED TRANSVERSE JOINT, COMPARATIVE HIGH TENSION CAN EXIST EITHER ON THE TOP OR BOTTOM OF THE SLAB WHEN THE WHEEL LOAD PASSES OVER THE JOINT, AND (4) THE STRESS IN THE INTERIOR PORTION OF A PLAIN SLAB AT SOME DISTANCE AWAY FROM A TRANSVERSE JOINT IS CONSIDERABLY LESS THAN THE STRESS ALONG THE OUTER EDGE.
