Book Guide for the Local Calibration of the Mechanistic empirical Pavement Design Guide

Download or read book Guide for the Local Calibration of the Mechanistic empirical Pavement Design Guide written by and published by AASHTO. This book was released on 2010 with total page 202 pages. 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.

This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Current pavement design methodology based on the AASHTO Design Guide uses an empirical approach based on the results of the AASHTO Road Test conducted in 1958. But limitations of the current guide led AAHSTO to publish the new Mechanistic Empirical Pavement Design Guide (MEPDG), which combines mechanistic and empirical methodology by using calculations of pavement responses, such as stress, strains, and deformations (mechanistic) using site specific inputs from climate, material, and traffic properties. As a new design guide and with large data inputs required, there are bound to be challenges. In this respect, the MEPDG is currently undergoing many changes with further research being conducted at the national, regional, and local levels into various aspects of the guide, especially in the areas of materials, climate, and traffic characteristics. It is hoped that the findings from various research studies will facilitate the implementaion of the MEPDG within national, regional, and local transporation agencies and professionals. Consequently, a North-West States' MEPDG User Group meeting was held in Oregon on March 9-10 to discuss the region's implementation plans and progress, related technical issues, and the future direction of the MEPDG. This report summarizes the findings from the meeting and seeks to outline the research needs necessary to facilitate the implementation of the MEPDG in the North-West region.

Book Mechanistic Empirical Pavement Design Guide  MEPDG  Method Implemented to Estimate Damage in Flexible and Rigid Pavements

Download or read book Mechanistic Empirical Pavement Design Guide MEPDG Method Implemented to Estimate Damage in Flexible and Rigid Pavements written by Tenzin Gusto and published by . This book was released on 2016 with total page 140 pages. Available in PDF, EPUB and Kindle. Book excerpt: The implementation of the Empirical-Mechanistic Pavement Design Guide (MEPDG) method for flexible and rigid pavements requires numerous input parameters. Most of these parameters can be easily determined while some require best estimates that are usually extracted from available literature. This thesis identifies the most critical input parameters in terms of their effects on the damage of pavements and their influence on the determination of the number of corrective maintenance cycles to be performed during the design life of pavements. It was found that for flexible pavement, change in the average monthly temperature by as little as results in large differences in the number of corrective maintenance cycles. Also, consistently with simple mechanics concepts, pavements on stiffer foundations performed better under the load and hence, required fewer number of the corrective maintenance cycles than those founded on more flexible soils. Also, variations in truck weights affected the outcome in terms of the estimated number of corrective maintenance cycles for flexible pavement. Hence, better estimates of the number of corrective maintenance cycles can be obtained when the analysis was based on larger numbers of truck samples. On the contrary, no significant difference in the final estimation of the number of corrective maintenance cycles was found for rigid pavements even when the average monthly temperatures were increased or decreased by as much as . Moreover, no major difference was observed when a larger sample of trucks was used as input for the analysis. Similarly, change in ambient temperature which is directly related to the differential temperature on the top and the bottom of the slab that may lead to the curling of the slab and faulting, was found not to be critical. Similar to the results obtained for flexible pavements, rigid pavement with stiffer foundation properties performed better in terms of the number of corrective maintenance cycles as they required fewer corrective maintenance cycles.

Book Sensitivity Analysis of Rigid Pavement Design Inputs Using Mechanistic empirical Pavement Design Guide

Download or read book Sensitivity Analysis of Rigid Pavement Design Inputs Using Mechanistic empirical Pavement Design Guide written by Alper Guclu and published by . This book was released on 2005 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement design procedures, available in the literature, do not fully take advantage of mechanistic concepts, which make them heavily rely on empirical approaches. Because of the heavy dependence on empirical procedures, the existing design methodologies do not capture the actual behavior of Portland cement concrete (PCC) pavements. However, reliance on empirical solutions can be reduced by introducing mechanistic-empirical methods, which is now adopted in the newly released mechanistic-empirical pavement design guide (MEPDG). This new design procedure incorporates a wide range of input parameters associated with the mechanics of rigid pavements. To compare the sensitivity of these various input parameters on the performance of concrete pavements, two jointed plain concrete pavement (JPCP) sites were selected in Iowa. These two sections are also part of the Long Term Pavement Performance (LTPP) program where a long history of pavement performance data exists. Data obtained from the Iowa Department of Transportation (Iowa DOT) Pavement Management Information System (PMIS) and LTPP database were used to form two standard pavement sections for the comprehensive sensitivity analyses. The sensitivity analyses were conducted using the MEPDG software to study the effects of design input parameters on pavement performance of faulting, transverse cracking, and smoothness. Based on the sensitivity results, ranking of the rigid pavement input parameters were established and categorized from most sensitive to insensitive to help pavement design engineers to identify the level of importance of each input parameter. The curl/warp effective temperature difference (built-in curling and warping of the slabs) and PCC thermal properties are found to be the most sensitive input parameters. Based on the comprehensive sensitivity analyses, the idea of developing an expert system was introduced to help the pavement design engineers identify the input parameters that they can modify to satisfy the predetermined pavement performance criteria. Predicted pavement distresses using the MEPDG software for the two Iowa rigid pavement sites were compared against the measured pavement distresses obtained from the Iowa DOT's PMIS and comparison results are discussed in this study.

Book excerpt: "This document provides guidance for all aspects of pavement design to the engineering practitioner. Current AASHTO literature focuses on specific pavement-related subjects, such as mechanistic-empirical (M-E) pavement design and pavement management. The Pavement Handbook attempts to fill the gaps in understanding for previously unaddressed subjects related to pavements, while still providing an overview of published subjects. In short, the Handbook is meant to be a 'one-stop shop' for pavement engineering. The fundamentals of pavement design are discussed in the second through fifth chapters. The reader is informed about various pavement types and their corresponding material components. Following is an indepth discourse on the structural pavement design analysis for each pavement type, with particular attention paid to M-E techniques. The impact of surface properties on friction, ride, and safety are thoroughly explained. The sixth chapter discusses pavement type selection strategies, whether the pavement is being newly constructed from the ground up or undergoing some type of restoration. Life-cycle costs are considered for selection optimization. Methods of construction for various pavement types are covered in the seventh chapter, including detailed guidance for both materials and construction specifications. Special emphasis is placed on quality management and its essential role for successful project completion. The testing and evaluation of existing pavements are the subjects of the eighth and ninth chapters. Visual distress surveys, nondestructive testing, and sampling and testing comprise the data acquisition techniques outlined for making educated assessments of pavement condition. The tenth and eleventh chapters detail treatments for existing pavements ranging from non-structural pavement preservation to structural rehabilitation. Performance expectations for each treatment are summarized. Managing pavements at all hierarchical levels is the focus of the twelfth chapter. Transitioning from distress data types and their collection protocol to database analysis methods, the outline is given for design life optimization. The thirteenth chapter ends the Handbook with thoughtful discussion of the pavement caretaker's role in selecting and re-using materials for environmentally sustainable design." -- Preface.
