EVALUATION OF FULL-DEPTH ASPHALTIC CONCRETE PAVEMENTS
This study was initiated to verify a newly-developed set of design curves for full-depth asphaltic concrete pavements. Quality control during construction was checked using nuclear density testers, Benkelman beams, and a Road Rater. During the couse of this study, an analysis system was developed to interpret the dynamic deflections as measured by the Road Rater and was confirmed by elastic theory. The thickness design curves were verified within the accuracy of construction variations. Rut depths measured in 1979 were analyzed in terms of potential rut depths resulting from consolidation under traffic due to lack of obtaining 100-percent of Marshall density during compaction immediately after paving. Potential rutting was calculated as the decimal equivalent of the quantity of 100 percent minus percent compaction times the layer thickness and the results accumulated from the surface downward. Advances in technology under this study have led to greater advances under succeeding studies. Traffic was monitored using automatic traffic counters, manual classification/volume counts, and weigh-in-motion scales installed in the pavement. (Author)
