Download or read book Investigation of AASHTOWare Pavement ME Design DARWin ME Performance Prediction Models for Iowa Pavement Analysis and Design written by Halil Ceylan and published by . This book was released on 2015 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Mechanistic-Empirical Pavement Design Guide (MEPDG) was developed under National Cooperative Highway Research Program (NCHRP) Project 1-37A as a novel mechanistic-empirical procedure for the analysis and design of pavements. The MEPDG was subsequently supported by AASHTO's DARWin-ME and most recently marketed as AASHTOWare Pavement ME Design software as of February 2013. Although the core design process and computational engine have remained the same over the years, some enhancements to the pavement performance prediction models have been implemented along with other documented changes as the MEPDG transitioned to AASHTOWare Pavement ME Design software. Preliminary studies were carried out to determine possible differences between AASHTOWare Pavement ME Design, MEPDG (version 1.1), and DARWin-ME (version 1.1) performance predictions for new jointed plain concrete pavement (JPCP), new hot mix asphalt (HMA), and HMA over JPCP systems. Differences were indeed observed between the pavement performance predictions produced by these different software versions. Further investigation was needed to verify these differences and to evaluate whether identified local calibration factors from the latest MEPDG (version 1.1) were acceptable for use with the latest version (version 2.1.24) of AASHTOWare Pavement ME Design at the time this research was conducted. Therefore, the primary objective of this research was to examine AASHTOWare Pavement ME Design performance predictions using previously identified MEPDG calibration factors (through InTrans Project 11-401) and, if needed, refine the local calibration coefficients of AASHTOWare Pavement ME Design pavement performance predictions for Iowa pavement systems using linear and nonlinear optimization procedures. A total of 130 representative sections across Iowa consisting of JPCP, new HMA, and HMA over JPCP sections were used. The local calibration results of AASHTOWare Pavement ME Design are presented and compared with national and locally calibrated MEPDG models.

Available in PDF, EPUB and Kindle. Book excerpt: Pavements represent the largest single area of investment in highway transport infrastructure. Like any large investment, they deserve good management. This is particularly so, because pavements are also subjected to fairly rapid deterioration. A total pavement management system (PMS) consists of a coordinated' set of activities, all directed toward achieving the best value for the available public funds in providing and operating smooth, safe and economical pavements. The measurement and prediction (modeling) of pavement performance is a cornerstone of any PMS for both network and project level, because it is necessary for both the financial planning/budgeting and pavement life cycle economic evaluation. A pilot PMS for Turkey's roads has been carried out for 72 hot-mix asphalt concrete sections within the Ankara region, The necessary data (including FWD deflections, surface distress, roughness, etc. were collected and evaluated. A follow-up to the network project was a study to develop a project level performance prediction model for Turkey's roads by using the network data. The results of the following study are reported in this paper. In one part of the study, a relationship between PQI (Pavement Quality Index) vs. cumulative traffic loading and age is developed by using multivariate linear regression analysis after class ification of the sections according to thickness (EGT), subgrade' strength (MK) and cumulative traffic loading (ESAL). In another part, a set of performance curves in terms of PSI vs. ESAL are drawn for different SN (structural number) values. These SN values are calculated by running the software DARWin of AASHT0'93 for Turkey's condition representing different compositions for different traffic and different subgrade strengths. In the third part of the study, the OPAC (Ontario Pavement Analysis o r! Costs) performance model which is based on a relationship between subgrade deflection and pavement deterioration, is modified for Turkey's roads which are extremely high trafficked when compared to Ontario's In order to achieve more reliable performance curves, it is recommended that all these approaches should be further verified by means of periodic data collection and evaluation.

Download or read book Developing Pavement Performance Prediction Models and Decision Trees for the City of Cincinnati written by Arudi Rajagopal and published by . This book was released on 2006 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the details of a study conducted to develop pavement performance prediction models and decision trees for various families of pavements, using the data available with the City of Cincinnati. Required data was acquired from city's pavement inventory database. The road network was divided into two classifications namely, major roads and minor roads. These roads were further grouped based on their structural makeup. Statistical regression models were developed for each group. A decision tree was developed to suggest appropriate maintenance and rehabilitation activities based on the condition of the pavement. The city engineers can use these models in conjunction with their pavement management system to predict the future condition of the highway network in Cincinnati and to implement cost effective pavement management solutions. Using the methodology developed in this study, the engineers can also further improve the accuracy of the models in the future.

This book was released on 2000 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: "The current performance-related specifications (PRS) methodology has been under development by the Federal Highway Administration (FHWA) for several years and has now reached a level at which it can be implemented by State highway agencies. PRS for highway pavements depend heavily on performance prediction models to determine the impact of varying levels of construction quality. This study focused on the improvement of the key distress and smoothness prediction models used in the PRS for jointed plain concrete pavement (JPCP). Performance models for transverse joint faulting, transverse slab cracking, transverse joint spalling, and smoothness (International Roughness Index [MI]) were evaluated and then improved substantially. This was accomplished using a comprehensive national database of JPCP performance data, along with sound statistical and engineering techniques. Performance model calibration guidelines were also developed so that a State cari calibrate any of these models specifically to its pavement performance data. The PaveSpec PRS demonstration software was upgraded to Version 3.0 under this study. Some of the specific improvements incorporated in PaveSpec 3.0 include: 1) incorporation ofyim proved distress indicator models, as well as the ability to calibrate or modify the default models, 2) sensitivity analysis capabilities, 3) expected pay charts, and 4) online help. Appendix A of this report contains a complete updated PaveSpec User's Guide"--Technical report documentation page

Available in PDF, EPUB and Kindle. Book excerpt: The Ontario Pavement Analysis of Costs system has been in service for Ontario asphalt flexible pavement design and performance prediction since the early 1970s. It uses a deflection-based deterministic model for selecting the best pavement structural design alternative in terms of pavement functional and structural performance and the total life-cycle costs. However, because of the existence of uncertainties and variations in pavement design variables and parameters in the pavement deterioration models, it is not adequate to apply deterministic models to all situations of pavement management. It is therefore necessary to predict pavement performance by employing probabilistic-based models. In this paper, a new concept of system conversion between a deterministic model and a probabilistic model is discussed first. A method by which a deterministic pavement performance prediction model, such as the Ontario asphalt pavement deterioration model, can be converted into a probabilistic model is presented. A transformed probabilistic model is constructed by generating a set of time-related nonhomogeneous Markovian transition probability matrices, which is determined by Monte Carlo simulation. Each of the transition probability matrices characterizes the pavement deterioration rate for the given pavement age and traffic characteristics. A Bayesian technique is then employed to update the predicted pavement performance in terms of the pavement condition state vectors and expected pavement condition state values by integrating additional information such as the actually measured performance data of the pavement.
