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.

"Most highway infrastructure authorities use pavement condition rating to assess the service life of a pavement and its ability to meet the needs of the travelling public. The Ministry of Transportation Ontario uses two interrelated measures, ride quality and distress manifestations, as the basis of its pavement condition rating scheme. Pavement condition rating is an essential component of the Ministry's pavement management system. This manual provides the what, why and how of pavement condition rating for flexible pavements." --Abstract.

Keeping asphalt-surfaced highways and roads in an acceptable condition is the major goal that departments of transportation and pavement engineers always strive to achieve. According to ASCE 2009 report card, an estimated spending of $186 billion is needed annually to substantially improve highways conditions. Hence, prediction models of current and future pavement condition should be rationalized and studied from cost effective perspective. In modeling the pavement condition, two major categories of models have been used: (1) deterministic and (2) stochastic. Existing models consider some factors that might be more critical than others, such as roughness measurements and distress information. They ignore other factors that could have a real effect on the accuracy of the pavement performance model(s), such as climate conditions. Therefore, the current research aims at developing a comprehensive condition-rating model that incorporates a wider range of possible factors significantly affecting flexible pavement performance. Data for this research were collected from the records of Nebraska Department of Roads (NDOR) called "Tab Files". In addition to a questionnaire that was designed and sent to pavement engineers and experts in North America. An integrated model was developed using Multi-Attribute Utility Theory (MAUT) and multiple regression analysis. Sensitivity analysis of the developed regression models is done using Monte-Carlo simulation to quickly identify the high-impact factors. Models' validation shows robust results with an average validity percent of 94% in which they can be utilized by Departments of Transportation (DOT) and/or Pavement Management Systems (PMS) as a useful tool for assessing and predicting pavement conditions.

Pavement condition surveys are necessary to evaluate the effect upon pavement life and service caused by various factors such as subgrade soil of the various classifications, subgrade densification, subgrade treatments, subgrade drainage, subbase materials and methods of placing, pavement materials, pavement design, pavement construction methods, traffic, maintenance materials and methods, and climatic conditions. Pavement condition is logically measured for Portland cement concrete pavements by the condition of joints and cracks, condition of the surface, and the amount of cracking and breakage. In addition, it is logically measured for pavements of the flexible type by the amount of cracking, type of cracking, raveling, rutting, shoving, settling, bleeding, and the area and depth of patches. Skid resistance and degree of bumpiness are pavement condition factors for both rigid and flexible pavements. Various types of condition surveys are outlined and suggestions made for making them.

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.
