INVESTIGATIONS INTO DYNAFLECT DEFLECTIONS IN RELATION TO LOCATION/TEMPERATURE PARAMETERS AND INSITU MATERIAL CHARACTERIZATION OF RIGID PAVEMENTS

This report presents a statistical analysis of Dynaflect deflection and slab temperature data to investigate different test location variables and temperature parameters that affect Dynaflect deflections measured on rigid pavement. A procedure is developed for making Dynaflect deflection measurements and applying a suitable temperature correction to deflections measured near the pavement edge. A computer program is included that will facilitate the estimation of temperature in suggested in the procedure of using elastic layered theory (static loading) based computer packages to back-calculate Young's moduli from the measured Dynaflect deflection basin. The "spectral analysis of surface waves" method and crosshole testing used on the Columbus site are also presented and discussed. (FHWA)
