EFFECT OF CONCRETE SHOULDERS, LANE WIDENING AND FROZEN SUBGRADE ON CONCRETE PAVEMENT PERFORMANCE. FINAL REPORT

This is the fourth and final report of a study to determine the effect of concrete shoulders, lane widening and frozen subgrade on concrete pavement performance. In this portion of the study, Falling Weight Deflectometer tests were conducted seasonally over a two-year period to determine the seasonal variation in pavement deflection. Tests were also conducted to determine the change in pavement deflection throughout the day. An analysis was run to verify earlier results determined by the Construction Technologies Laboratory of the Portland Cement Association.
