This book was released on 2009 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation's (VDOT's) current pavement design procedure is based on the 1993 AASHTO Guide for Design of Pavement Structures. In this procedure, a required structural capacity is calculated as a function of the anticipated service life, the serviceability of the pavement, and the number of equivalent loads applied. The concept of equivalent applied loads allows for the pavement designer to account for the damage caused by loads of varying magnitudes and axle configurations. Although pavement damage can be expressed per axle, expressing the damage in terms of the average amount of damage caused by a particular vehicle is more convenient. This is referred to as a truck factor, which is the average number of equivalent single-axle load (ESAL) applications per vehicle. VDOT's current pavement design procedure subdivides truck traffic into two categories, i.e., single-unit trucks and combination trucks, and was based on studies performed in the early 1990s. Over the last few years, VDOT has installed weigh-in-motion (WIM) devices at 15 locations around the state that measure the loads actually applied by vehicles in the travel lanes. These WIM stations allow for continuous data collection that was previously not available and therefore can provide a better representation of actual traffic loading. This study developed updated truck ESAL factors based on WIM data from June 2007 through May 2008 in Virginia. These factors were found to be 0.46 for single-unit trucks and 1.05 for combination trucks using flexible pavements and 0.59 for single-unit trucks and 1.59 for combination trucks using rigid pavements. The updated truck ESAL factors determined in this study should be incorporated into VDOT's pavement design procedure. Using the updated truck ESAL factors recommended in this study will allow a more optimal pavement design that more accurately reflects the traffic loading on roadways in Virginia.

Book excerpt: Pavements are engineered structures essential to transportation, commerce and trade, and everyday life. In order for them to perform as expected, they must be designed, constructed, maintained, and managed properly. Providing a comprehensive overview of the subject, Pavement Engineering: Principles and Practice, Second Edition covers a wide range of topics in asphalt and concrete pavements, from soil preparation to structural design and construction. This new edition includes updates in all chapters and two new chapters on emerging topics that are becoming universally important: engineering of sustainable pavements and environmental mitigation in transportation projects. It also contains new examples and new figures with more informative schematics as well as helpful photographs. The text describes the significance of standards and examines traffic, drainage, concrete mixes, asphalt binders, distress and performance in concrete and asphalt pavements, and pavement maintenance and rehabilitation. It also contains a chapter on airport pavements and discusses nondestructive tests for pavement engineering using nuclear, deflection-based, electromagnetic, and seismic equipment. The authors explore key concepts and techniques for economic analysis and computing life-cycle cost, instrumentation for acquiring test data, and specialty applications of asphalt and concrete. The Second Edition includes more relevant issues and recently developed techniques and guidelines for practical problems, such as selection of pavement type, effect of vehicle tires, and use of smart sensors in rollers and software for drainage analysis. This book presents in-depth, state-of-the-art knowledge in a range of relevant topics in pavement engineering, with numerous examples and figures and comprehensive references to online resources for literature and software. It provides a good understanding of construction practices essential for new engineers and materials processing and construction needed for solving numerous problems.
Download or read book Analysis and Determination of Axle Load Spectra and Traffic Input for the Mechanistic Empirical Pavement Design Guide written by Yi Jiang and published by Purdue University Press. This book was released on 2008-03-01 with total page 110 pages. Available in PDF, EPUB and Kindle. Book excerpt: The values of equivalent single axle loads (ESAL) have been used to represent the vehicle loads in pavement design. To improve the pavement design procedures, a new method, called the Mechanistic-Empirical Pavement Design Guide (MEPDG), has been developed to use the axle load spectra to represent the vehicle loads in pavement design. These spectra represent the percentage of the total axle applications within each load interval for single, tandem, tridem, and quad axles. Using axle load spectra as the traffic input, the MEPDG method is able to analyze the impacts of varying traffic loads on pavement and provide an optimal pavement structure design. In addition, the new method can be used to analyze the effects of materials and the impacts of seasons, to compare rehabilitation strategies, and to perform forensic analyses of pavement conditions. The MEPDG utilizes mechanistic-empirical approaches to realistically characterize inservice pavements and allows the full integration of vehicular traffic loadings, climatic features, soil characteristics, and paving materials properties into the detailed analysis of pavement structural behaviors and the resulting pavement performance. In order to provide the traffic data input required by the MEPDG, the Indiana Department of Transportation (INDOT) made an effort to obtain truck traffic information from the traffic data collected through weigh-in-motion (WIM) stations. This study was conducted to create the truck traffic spectra and other traffic inputs for INDOT to implement the new pavement design method. Furthermore, the INDOT AADT data were used in this study to analyze the spatial distributions of the traffic volumes in Indiana and to obtain the spatial distributions of traffic volumes.

Available in PDF, EPUB and Kindle. Book excerpt: For a given road segment, accurate estimates of current and projected traffic [in terms of Equivalent Single Axle Loads (ESALs)] can result in significant cost savings, either from the standpoint of initial construction cost or future maintenance and rehabilitation cost. The primary objective of this project is to prepare a new ESAL design table for Arizona's highway network. This new table is based on analysis of current traffic data collection procedures, traffic forecasting methodology, and ESAL development procedures, including the assignment of traffic ESAL levels to the various highway segments.
