Use of the Minnesota Department of Transportation pavement management data to evaluate the effect of pavement preservation activities on pavement performance is described. Evaluation focuses on bituminous over aggregate base pavements constructed between 1985 and 2005. Pavement data were initially divided into subsets of data: one for pavements with no preservation and the other for pavements that received preservation. The subset that included preservation activities was further subdivided for comparison into those that received thin mill and overlay or thin overlays and those that did not. Data analysis showed that preservation improved pavement performance and that thin overlays and thin mill and overlays were the preservation treatments that provided the greatest performance improvements but were used for the poorest performing pavements.
