Evaluation of Base Courses for Flexible Pavements
Nineteen pavement sections monitored over a period of approximately ten years have been evaluated to determine the influence of base course parameters on the performance of primary flexible pavement systems in Piedmont, North Carolina. The research relied essentially on the Present Serviceability Rating concept as a measure of performance. The findings of the research indicates roughness measures are insensitive to changes in subjective performance, present design procedures are adequate and probably conservative, at least, for the pavements studied. Bituminous concrete base courses are not necessarily structurally superior to coarse aggregate base courses, and Benkleman beam deflections are poor indicators of performance.
