This book was released on 2009-06-01 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, state highway agencies have come to understand the need for high quality pavement condition data at both the project and network levels. At the same time, agencies also realize that they have become too dependent on contractors to ensure the quality of the delivered data without any means to independently assure the quality of these data. This research study therefore aims to investigate the inherent variability of the automated data collection processes and proposes guidelines for an automated data collection quality management program in Indiana. In particular, pavement roughness data (in terms of IRI) and pavement surface distress data (in terms of PCR and individual pavement surface distress ratings) are considered in this study. Quality control protocols adopted by the contractor are reviewed and compared against industry standards. A complete quality control plan is recommended to be adopted for all phases of the data collection cycle: preproject phase, data collection phase, and post-processing phase. Quality assurance of pavement condition data can be viewed in terms of (i) completeness of the delivered data for pavement management; (ii) accuracy, precision and reliability of pavement roughness data; and (iii) accuracy, precision and reliability of individual distress ratings and an aggregate pavement condition rating. An innovative two-stage approach is developed in this study to evaluate delivered data for integrity and completeness. Different techniques and performance measures that can be used to evaluate pavement roughness and pavement surface distress data quality are investigated. Causes for loss in IRI and PCR accuracy and precision are identified and statistical models are developed to relate project- and network-level IRIs and PCRs. Quality assurance procedures are then developed to allow highway agencies improve their pavement condition data collection practices and enhance applications in the pavement management systems.

Available in PDF, EPUB and Kindle. Book excerpt: The Ohio Department of Transportation (ODOT) has been collecting 3D digital data on their pavement network since 2014. This data contains a variety of information derived from 3d laser scans of the pavement. While ODOT has been using the data to meet federal HPMS reporting requirements of pavement condition, the agency wished to leverage this wealth of data to aid their pavement management system and transition from a manual pavement condition survey to an automated one. This research aims to provide ODOT a means to interpret the data and use it to make the same decisions as the existing pavement management system. Topics include analysis and development of a new rating methodology for automated distress detection and classification as well as deterioration models and decision trees for the new rating methodology. The rating system was developed using comparisons with existing manual ratings and automated data collected from 2014 through 2018. Additionally, the report covers how to implement this methodology and how it impacts pavement management decisions.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

Available in PDF, EPUB and Kindle. Book excerpt: The National Performance Management Measures; Assessing Pavement Condition for the National Highway Performance Program provided in Subpart C of 23 CFR Part 490 includes an alternative method to report pavement conditions for Interstate and non-Interstate National Highway System locations where the speed limit is less than 40 mph.(1) This alternate method uses present serviceability ratings (PSR) to report pavement condition in lieu of using the International Roughness Index, measures of rutting and faulting, and percentage of cracking where the posted speed limit is less than 40 mph. Per 23 CFR 490.309(b)(1)(iv), the portion of the Interstate mainline highway pavements where PSR is allowable includes border crossings and toll plazas.(1) To address stakeholder concerns about the appropriate application of PSR, the Federal Highway Administration (FHWA) developed resources to support agencies that prefer to use PSR as an alternate pavement-condition-rating system, where permitted. In addition, many agencies do not collect PSR on their pavement segments; instead, they use Pavement Condition Index (PCI) or other indices computed from measured surface distresses in their pavement management systems. In light of this, section 490.309(b)(2)(iii) also allows State DOTs to convert other pavement-condition-assessment methods (e.g., the U.S. Army Corps of Engineers PCI) to PSR if the State establishes to FHWA's satisfaction that the conversion produces pavement condition ratings equivalent to the PSR method. In support of this rule, FHWA has developed this report to provide an approach for estimating PSR from measured surface distress data. It also illustrates correlations between commonly used indices and the PSR, as described in the Highway Performance Monitoring System Field Manual.(3) The appendix includes a guide for using a Microsoft(R) Excel(R)-based PSR Computation Workbook that was developed to assists with estimating PSR from measured surface distresses.(2)
