Data used in the study described consist of over 5000 nuclear density readings by the back-scatter method and correlated with cores for accuracy and statistical variation. All nuclear density measurements were compared to twice daily 75-blow Marshall laboratory values to minimize the influence of mix variations. This study compares roller patterns wherein the vibratory roller replaced either or both the breakdown steel and intermediate pneumatic normally used. The density results over the full-width of a 3.65-m pavement overlay was also compared to determine the compaction variation whereby wheel path rutting exists.
