Book Description
This study was conducted to review the Pavement Condition Rating (PCR) methodology currently used by the Ohio DOT. The results of the literature search conducted in this connection are described ih thereport. An analysis of the PCR data collected by the ODOT in the past 11 years (1985-95) indicated that there were some distresses which were rarely observed in the past. The reasons for such occurrences and the use of this information to enhance the current system are discussed in the report. Statistical method known as: Classification Tree, was used to analyze the PCR data for (Ir)a ting the pavements, and (2) assigning the maintenance and/or rehabilitation (M & R) actions, when the distresses of the individual pavements were known. The results of this analysis indicated that due to non-linear nature of PCR, this model is able to assess the PCR better than the current linear model of estimating the PCR. An expert opinion survey was designed and conducted to collect data for developing new weights of pavement distresses using a combination of statistical methods: "Classification Tree" and "Proportional Odds Model". The PCR values obtained from new and old distress weights were compared and the results of these comparisons are discussed in the report. Statistical analysis of the PCR data for the year 1996 was performed to determine a suitable sample size which can be used to survey the network for collecting the PCR data of the network for Pavement Management purposes and selecting the pavements for inclusion in the annual M & R program of ODOT. This report contains recommendations for revising the list of distresses of each pavement type, developing a non-linear model to assess the pavement condition and M & R needs of a given pavement, a suitable sampling procedure for surveying the network and revising the definitions of some distresses of each pavement type.

Book Description
This manual categorizes distress manifestations and provides illustrations of each category to lend uniformity to reporting and interpretation. Descriptions of the density of occurrence and the severity of each type of distress manifestation are made to conform to standard words which precisely express the relative density or severity on a scale of 1-5. Probable causes of each distress manifestation are presented, together with comments on progressive deterioration or other behaviour which might affect remedial treatment. Possible remedial measures are included under each distress manifestation.

Book Description
Evaluation of pavement condition is the principle source of information for the effective management of the road network for local and state transportation agencies. However, transportation agencies in the United States are using different pavement rating systems to evaluate their pavement condition. The data collection system, measurement units, and calculation techniques have been modified and updated by several states to incorporate new technological development with time. Several transportation agencies are willing to update their old pavement rating systems while others elected to gradually switch to more accurate rating systems. This study focuses on the potential enhancements on the Pavement Rating Index (PRI) used by Nevada Department of Transportation (NDOT) to make it more consistent with nationally applied systems such as the Pavement Condition Index (PCI) developed by U.S. Army Construction Engineering Research Laboratory. Pavement condition data that were utilized to calculate PRI over the last 15 years were converted into PCI compatible format using a suitable conversion technique. Estimated PCI values were plotted against the corresponding PRI value showed moderate correlation with R2 value of 0.56. The current PRI system was then enhanced to eliminate some of its deficiencies. The statistical relationship between the enhanced PRI and PCI showed improved correlation with R2 value of 0.75. The study concluded that a successful correlation between the PRI system and the PCI system can be achieved in Nevada while maintaining the use of the historical pavement condition data. This study also suggests using a recommended PRIr system which adds the impact of roughness and friction onto the enhanced PRI system. Finally, this study compares the road maintenance strategies suggested by the current PRI system and the PRIr system with the time based schedule and the actual activities applied on the pavement section. This comparison concluded that, while both the PRI and PRIr systems show good correlations with the time based schedule and actual activities for assigning preventive and corrective maintenance strategies, the PRIr system showed improved correlations with the time based schedule and actual activities for assigning the overlay strategy. The PRIr system is recommended for implementation by NDOT due to its consistency with national systems (i.e., PCI) and its superior correlations with time based schedule and actual activities for overlays which leads to significant savings of rehabilitation funds.
