STUDIES OF SUBGRADE PRESSURES UNDER FLEXIBLE ROAD SURFACES

THE RESULTS OF LABORATORY PRESSURE MEASUREMENTS TAKEN UNDER 4 IN., 6 IN. AND 8IN. OF STONE SCREENINGS PLACED ON A SUBGRADE AND SUBJECTED TO 4,000, 8,000 AND 12,000-LB WHEEL LOADS ARE REPORTED. IN-SITU LOAD-INDENTATION TESTS WERE ALSO MADE ON THE SUBGRADE AS WELL AS ON THE SURFACING MATERIAL, IN AN EFFORT TO TIE IN THE PRESENT TESTS WITH SUBSEQUENT INVESTIGATIONS. THIS REPORT IS MERELY ONE OF PROGRESS, BUT IT IS FELT THAT THE RESULTS MAY BE USEFUL IN THE LATER FORMULATION OF A THEORY FOR FLEXIBLE ROAD DESIGN. /AUTHOR/
