This book was released on 2003 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Virginia Department of Transportation (VDOT) is preparing to implement the mechanistic-empirical pavement design methodology being developed under the National Cooperative Research Program's Project 1-37A, commonly referred to as the 2002 Pavement Design Guide (2002 Guide). The developers of the 2002 Guide have stated that transportation agencies in compliance with the Federal Highway Administration's Traffic Monitoring Guide will have the traffic data necessary to implement the new pavement design approach. The 2002 Guide is structured in a hierarchical manner with three pavement design levels. For Level 1 designs, all project-specific data will be collected, including axle load spectra information (and axle loadings by vehicle classification) and vehicle classification counts at the project location. For Level 2 designs, regional and project-specific data will be applied. For Level 3 designs, estimated project-specific and statewide average or default data will be used in the analysis. The purpose of this effort was to develop a plan to position VDOT to collect traffic and truck axle weight data to support Level 2 pavement designs. This report serves as the basis for implementing and maintaining the truck weigh program necessary for the new pavement design approach and provides data for the current pavement design process used in Virginia (i.e., the 1993 pavement design methodology of the American Association of State Highway and Transportation Officials). To keep program costs at a minimum, the proposed traffic data program for pavement design takes advantage of the flexibility permitted in the Traffic Monitoring Guide and the availability of weigh-in-motion data from the Virginia Department of Motor Vehicles. Truck weight Groups 1 and 2, which consist of interstate and arterial roads, where the majority of truck loading occurs, are the first priority for implementation. A traffic data plan and a phased approach to implement the plan were proposed.

Available in PDF, EPUB and Kindle. Book excerpt: As AASH is expected to eventually adopt the MEPDG at its primary pavement design method, it is critical that the SDDOT become familiar with the MEPGD documentation and associated design software. The research conducted under this project was a first step toward achieving this goal.

This book was released on 2012 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Proper characterization of traffic data is a prerequisite for the determination of appropriate traffic inputs to Mechanistic-Empirical Pavement Design Guide (MEPDG). The development of proper traffic inputs helps reflect the traffic conditions over the life of pavement which would decrease the maintenance, repair and traffic disruptions and improve the traffic conditions of a road network. The objective of the study was to characterize the traffic data and suggest the sitespecific, regional or state wide average values for traffic inputs to MEPDG for New York State. Vehicle class distribution (VCD), monthly distribution factors (MDF), hourly distribution factors (HDF), average number of axle groups per vehicle (AGPV) and axle load spectra were obtained from vehicle classification and WIM sites in New York State for the years of 2007-2011. These traffic data was processed with TrafLoad software. Cluster analysis was performed on the processed VCD, MDF and HDF data collected during the time period. This statistical analysis could not be done for AGPV values and axle load spectra due to the unavailability of sufficient number of WIM sites. However, MEPDG runs were carried out to investigate the effect of the variability of traffic inputs on the pavement performance of typical new flexible and rigid pavement structures. The statistical analysis showed consistent results for VCD and HDF over the years. However, the results of statistical analysis on MDF were not consistent over the time period. Site specific values for VCD, MDF, AGPV and axle load spectra showed little variation with statewide average values after the cluster analysis and MEPDG runs for the vehicle classification and WIM data of the year of 2010. This was observed for both flexible and rigid pavements. However, HDF did not show any effect on the design of pavement with MEPDG. These findings were also verified from the analysis of vehicle classification and WIM data of the other years.

Available in PDF, EPUB and Kindle. Book excerpt: This guide provides guidance to calibrate the Mechanistic-Empirical Pavement Design Guide (MEPDG) software to local conditions, policies, and materials. It provides the highway community with a state-of-the-practice tool for the design of new and rehabilitated pavement structures, based on mechanistic-empirical (M-E) principles. The design procedure calculates pavement responses (stresses, strains, and deflections) and uses those responses to compute incremental damage over time. The procedure empirically relates the cumulative damage to observed pavement distresses.

Book excerpt: This zipped file is composed of several PDFs (instructor guide, student guide, and a PowerPoint Presentation) for a training workshop meant to provide the methodologies for generating and using site-specific Mechanistic-Empirical-compatible traffic data for flexible and rigid pavement designs. The half-day course covers: 1. Traffic data sources to obtain the applicable M-E traffic data. 2. Traffic data parameters calculated and generated using the collected traffic data such as traffic volume, speed, classification, and weight data. 3. Traffic data inputs required for pavement design (for FPS and ME design software). 4. The traffic data storage system (The T-DSS) to store and provide ME-compatible traffic data support. 5. Data analysis macros and clustering algorithms to automatically analyze and generate the ME-compatible traffic data

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this research study was to assess and address the implications of the axle load spectra approach proposed by the M-E Design Guide. In addition, recommendations were developed regarding traffic data needs and availability to aid in deciding the installation locations of future WIM stations in Texas. A methodology for specifying the required accuracy of WIM equipment based on the effect that this accuracy has on pavement performance prediction was also developed. Regarding traffic volume forecasting, a methodology is presented that allows optimum use of available data by simultaneously estimating traffic growth and seasonal traffic variability.

Available in PDF, EPUB and Kindle. Book excerpt: Highway agencies across the nation are moving towards implementation of the new AASHTO Mechanistic-Empirical Pavement Design Guide (MEPDG) for pavement design. The benefits of implementing the MEPDG for routine use in Ohio includes (1) achieving more cost effective and reliable pavement designs, (2) lower initial and life cycle costs to the agency, and (3) reduced highway user impact due to lane closures for maintenance and rehabilitation of pavements. Implementation of the MEPDG is a process that requires time and agency resources (staffing, training, testing facilities including equipment, and so on). A key requirement is validating the MEPDG's nationally calibrated pavement distress and smoothness prediction models when applied under Ohio conditions and performing local calibration if needed. Feasibility of using the MEPDG's national models in Ohio was investigated under this study using data from a limited number of LTPP projects located in Ohio. Results based on limited data showed inadequate goodness of fit and significant bias in a number of the MEPDG new HMA pavement and JPCP performance prediction models. Limited recalibration of these models showed promising results indicating that a full-scale recalibration effort using a more extensive database assembled from projects located throughout the state is feasible.
