EVALUATION OF THE VARIATION IN PAVEMENT PERFORMANCE BETWEEN ODOT DISTRICTS
The purpose of this study was to determine if the perceived performance differences among Ohio Department of Transportation (ODOT) Districts are caused mainly by differences in traffic loading and climate, and if differences in materials, treatment type, and treatment timing are also significant factors. A comprehensive pavement information database was developed as part of this research. The data included in this database were used to analyze the performance trend of the priority system pavements. Pavement performance is found to be influenced by pavement type (i.e., rigid, flexible, or composite), traffic loading, climate (particularly, snowfall amount), and material quality. For asphalt overlays, pavement condition prior to overlay, i.e., treatment timing, and overlay thickness also affect the performance. The median survival time to next treatment for new rigid pavements is nearly 16 years; for new flexible pavements is roughly 12 years; and for asphalt overlays is about 8 years. Overlays on flexible pavements perform better and last longer than on composite pavements. Durability of aggregates (in terms of soundness) also affects overlay performance. In general, priority system pavement performance and average pavement conditions have improved since the mid-1990s due to improved material specifications, design, and construction quality control. It is recommended that future funding allocation formula considers percentage of composite pavements, traffic loadings, snowfall amount, and aggregate quality in each District. Using only aggregates with good durability is strongly recommended. Replacing composite pavements through reconstruction will also help improve long term performance.
