FIELD INVESTIGATION FOR FLEXIBLE PAVEMENT DESIGN

A REVIEW IS MADE OF THE METHOD USED BY THE U. S. ENGINEER DEPARTMENT FOR MAKING BEARING TESTS ON AIRPORT RUNWAYS AND SUBGRADES WITH LOADS AND BEARING AREAS COMPARABLE TO THOSE OF PRESENT DAY MILITARY PLANES. THE RELATIVE EFFECT OF THE STRESSES PRODUCED BY A LARGE MILITARY PLANE AND BY A HEAVY LOADED TRUCK IS ILLUSTRATED. LOAD-DEFORMATION RESULTS ARE GIVEN FOR BEARING TESTS MADE (1) ON THE SURFACE, THE BASE COURSE AND THE CONFINED SUBGRADE OF A BITUMINOUS STABILIZED PROJECT; (2) ON A GOOD, A FAIR, AND A FAILED SECTION OF AN ASPHALT PAVEMENT OF A COMMERCIAL AIRPORT, AND (3) ON A POORLY, A PARTIALLY, AND A WELL CONSOLIDATED SUBGRADE. /AUTHOR/
