Book excerpt: The objective of this research study was to develop guidelines for portland cement concrete (PCC) material inputs to the AASHTOWare Pavement ME Design program. The AASHTOWare Pavement ME Design is the software program used by the Mississippi Department of Transportation (MDOT) to develop pavement design alternatives based on the mechanistic-empirical pavement design guide (MEPDG) procedure originally developed under National Cooperative Highway Research Program (NCHRP) Projects 1-37A, 1-40D, and 20-07/Task 288 & 327. MDOT has conducted several research projects to support the implementation of the MEPDG and for increasing the accuracy of the distress prediction models calibrated for local conditions and material sources. The current project focuses on PCC material inputs that represent the mix designs, cementitious materials, and the aggregate sources that will be used in future paving projects. This report provides a summary of laboratory test results of 20 mix designs that include five different aggregate sources and four different options for supplementary cementitious materials (SCM) for partial cement replacement. The laboratory test results represent level 1 and 2 PCC material inputs and report the flexural strength, compressive strength, elastic modulus, poisson's ratio, coefficient of thermal expansion (CTE), and percent length change measurements. Strength and modulus data, are reported for 7, 14, 28, and 90 days as required by the MEPDG. The CTE measurements are reported at 28-days, while the shrinkage length change measurements are reported for ages of 7, 11, 14, 21, 35, 63, 119, and 231 days. Level 2 correlation equations were developed based on compressive strength and other index properties to estimate flexural strength and elastic modulus. In general, these models demonstrate a slight deviation for the default level 2 models used in the global calibration of the MEPDG. Level 2 equations were also developed for each aggregate type and it is recommended that future efforts by MDOT for the recalibration of the rigid pavement distress prediction models should examine the sensitivity of these level 2 correlation equations and provide recommendations in the MDOT Design Manual.

Book excerpt: With the completion of the Mechanistic-Empirical Pavement Design Guide (MEPDG) and the recent designation of the MEPDG software as "AASHTOWare® Pavement ME Design," the standard for CRCP design has undergone significant changes from the 1993 AASHTO Pavement Design Guide. CRCP performance problems observed in the past, such as material durability, base erosion, steel placement and content, and construction methods have been addressed, and the improved pavement design procedure reflects modern construction practices, pavement layer materials, specifications, and best concrete pavement engineering practices. The primary purpose of this technical summary is to provide engineers with the basic mechanistic-empirical design background and criteria utilized in the AASHTO Pavement ME Design software for CRCP. Secondly, this technical summary describes the key CRCP design inputs to assist the pavement engineer through the CRCP design process with the AASHTO Pavement ME Design software, including identifying the most sensitive design inputs and features. Finally, example problems are included in this document to demonstrate the robustness of the new design software for both new CRCP and CRCP overlays in different climatic zones. It is expected that as the mechanistic-empirical design procedure for CRCP continues to evolve, refinements in the failure mechanisms and data inputs likely will be made, providing even greater reliability in the design process.

Book Synopsis Guide for the Local Calibration of the Mechanistic-empirical Pavement Design Guide by :
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.

Available in PDF, EPUB and Kindle. Book excerpt: "Abstract: The AASHTOWare Pavement METM Design is the next generation of AASHTO pavement design software, which builds upon the newly developed NCHRP Mechanistic-Empirical Pavement Design Guide (MEPDG). Pavement METM reflects a major change in the methods and procedures engineers use to design pavement structure and represents the most current advancements in pavement design. In preparation for DOTD to adopt the new design guide, there is an urgent need to evaluate the MEPDG pavement design software based on typical Louisiana pavement structures and local conditions. This study selected a total of 162 projects (pavement sections) from the existing DOTD highway network for the evaluation of MEPDG pavement design, local calibration, and validation of Pavement ME in Louisiana. The selected projects consisted of flexible pavements with five types of base (asphalt concrete base, rubblized PCC base, crushed stone or recycled PCC base, soil cement base, and stabilized base with a stone interlayer), rigid pavements with three types of base (unbound granular base, stabilized base, and asphalt mixture blanket), and HMA overlay on top of existing flexible pavements. Pavement design information including structure, materials, and traffic were retrieved from multiple network-level data sources at DOTD. A Louisiana default input strategy of Pavement ME that reflects Louisiana’s condition and practice was developed from results of sensitivity analysis. In addition, based on a consensus distress survey and pavement management system (PMS) distress triggers, the design reliability and performance criteria were established for different highway classes in Louisiana. The predicted performance from the Pavement ME was then compared with the corresponding measured performance retrieved from PMS. The analysis results indicate that the Pavement ME’s nationally-calibrated distress models generally under-predict alligator cracking, but over-predict rutting for DOTD’s flexible pavement types. For rigid pavements, Pavement ME over-predicts slab cracking but under-predicts joint faulting. For those nationally-calibrated distress models that showed constant bias and large variation, local calibration was carried out against the performance data retrieved from PMS. After the local calibration, the Pavement ME designs were verified by additional projects outside of the evaluation projects’ pool. Based on the results of this study, an implementation guideline document was prepared. The document contains all necessary design input information and calibration coefficients for DOTD to use the latest MEPDG software on a day to day basis for design and analysis of new and rehabilitated pavement structures in Louisiana."--Technical report documentation page.

Available in PDF, EPUB and Kindle. Book excerpt: "TRB's National Cooperative Highway Research Program (NCHRP) Report 810: Consideration of Preservation in Pavement Design and Analysis Procedures explores the effects of preservation on pavement performance and service life and describes three different approaches for considering these effects in pavement design and analysis procedures. The report may serve as a basis for developing procedures for incorporating preservation in the American Association of State Highway and Transportation Officials (AASHTO) Mechanistic-Empirical Pavement Design Guide: A Manual of Practice (MEPDG) and the AASHTOWare Pavement ME Design software. Initially, the scope of this project intended to develop procedures for incorporating pavement preservation treatments into the MEPDG design analysis process that would become part of the MEPDG Manual of Practice. However, it was determined that sufficient data were not available to support the development of such procedures. Appendices A through I are available online only." --
