SOIL SUPPORT AND STRUCTURAL COEFFICIENTS FOR FLEXIBLE PAVEMENT STRUCTURES IN PENNSYLVANIA

AN INVESTIGATION OF STRUCTURAL COEFFICEIENTS AND SOIL SUPPORT VALUES HAS BEEN UNDERTAKEN UTILIZING DATA OBTAINED FROM IN-PALCE TESTING OF IN-SERVICE FLEXIBLE PAVEMENTS. WHILE SOME OF THE PARAMETERS PRESENTLY USED ARE IN GOOD AGREEMENT WITH THE OBSERVED DATA, A FEW REQUIRE FURTHER INVESTIGATION. IN PARTICULAR, THE INFLUENCE OF PAVEMENT AGE ON THE STRUCTURAL COEFFICIENTS OF LIME AND CEMENT STABILIZED BASES REQUIRES FURTHER INVESTIGATION. DIFFICULTIES IN PREDICTING PAVEMENT SERVICE LIFE ON THE BASIS OF PAST PERFORMANCE RENDER FIRM CONCLUSIONS CONCERNING SOIL SUPPORT CHARACTERISTICS IMPOSSIBLE. /AUTHOR/
