Book Synopsis Automated Pavement Condition Surveys by : Linda M. Pierce
Download or read book Automated Pavement Condition Surveys written by Linda M. Pierce and published by . This book was released on 2019 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: TRB's National Cooperative Highway Research Program (NCHRP) Synthesis 531 documents agency practices, challenges, and successes in conducting automated pavement condition surveys. The report also includes three case examples that provide additional information on agency practices for conducting automated pavement surveys. Pavement condition data is a critical component for pavement management systems in state departments of transportation (DOTs). The data is used to establish budget needs, support asset management, select projects for maintenance and preservation, and more. Data collection technology has advanced rapidly over the last decade and many DOTs now use automated data collection systems.
Book Synopsis Automated Pavement Condition Data Collection Quality Control, Quality Assurance, and Reliability by : Ghim Ping Ong
Download or read book Automated Pavement Condition Data Collection Quality Control, Quality Assurance, and Reliability written by Ghim Ping Ong and published by Purdue University Press. 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.

Book Synopsis Pavement Condition Surveys by : National Research Council (U.S.). Highway Research Board
Download or read book Pavement Condition Surveys written by National Research Council (U.S.). Highway Research Board and published by . This book was released on 1957 with total page 70 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Book Synopsis Data Integration for Pavement by : Majed Alinizzi
Download or read book Data Integration for Pavement written by Majed Alinizzi and published by . This book was released on 2017-12-15 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This study was in two parts. The first part established and demonstrated a framework for pavement data integration. This is critical for fulfilling QC/QA needs of INDOT¿s pavement management system, because the precision of the physical location references is a prerequisite for the reliable collection and interpretation of pavement data. Such consistency is often jeopardized because the data are collected at different years, and are affected by changes in the vendor, inventory, or referencing system or reference points. This study therefore developed a ¿lining-up¿ methodology to address this issue. The applicability of the developed methodology was demonstrated using 2012-2014 data from Indiana¿s highway network. The results showed that the errors in the unlined up data are significant as they mischaracterize the true pavement condition. This could lead to the reporting of unreliable information of road network condition to the decision makers, ultimately leading to inappropriate condition assessments and prescriptions. Benefits of the methodology reverberate throughout the management functions and processes associated with highway pavements in Indiana, including pavement performance modeling, optimal timing of maintenance, rehabilitation, and reconstruction (MRR), and assessment of the effectiveness of MRR treatments and schedules.The second part of the study developed correlations for the different types of pavement distresses using machine learning algorithms. That way, the severity of any one type of distress can be estimated based on known severity of other distresses at that location. The 2012-2014 data were from I-70, US-41, and US-52, and the distress types considered are cracking, rutting, faulting, and roughness. Models were developed to relate surface roughness (IRI) to pavement cracks, and between the different crack types, with resulting degrees of confidence that varied across the different crack types and road functional classes. In addition, for each functional class and for each crack type, models were built to relate crack depth to crack width. The concept can be applied to other distress types, such as spalling, bleeding, raveling, depression, shoving, stripping, potholes, and joint distresses, when appropriate data are available.
