Download or read book Pavement Service Life written by Wisconsin. Department of Transportation and published by . This book was released on 2004 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: We surveyed AASHTO Research Advisory Committee members around the country. Survey responses indicated that service life typically is understood as a measure in years from construction to first rehabilitation or overlay, and as no verifiable actual (rather than estimated) service life tracking has been conducted for periods of 20 or more years, this necessarily entails calculations and estimates. Occasionally service life may be measured merely in terms of performance indicators or condition indices, but rarely in traffic loading terms such as ESALs or any other measure. In this report, we will look first at the survey results, then at specific states, starting with those with climates similar to Wisconsin, and moving then to other states. We also look briefly at Australian research and at work reported by the American Concrete Pavement Association and the Asphalt Pavement Alliance. In each of these sections we highlight definitions of service life and the pavement type categories to which the agency applies the term.

Download or read book Integrating the Flexible Pavement Life Cycle written by and published by . This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, research and analysis of asphalt pavements have been siloed into pavement structural design, pavement material selection, and pavement service life. In order to achieve a truly perpetual pavement and potentially minimize life-cycle economic costs and environmental impacts, the pavement structural design and material design must also be integrated with pavement preservation and maintenance decisions. TRB's Transportation Research Circular E-C286: Integrating the Flexible Pavement Life Cycle details a workshop that was held at the 101st TRB Annual Meeting in January 2022.

It includes a review of domestic literature and a survey of current practices in North America. The appendices include a primer on pavement design and construction, the benefits of preventive maintenance of pavements, a summary of the questionnaire data collected, a simulation of pavement management strategies, and an example process to demonstrate the cost- effectiveness of preventive maintenance.
Download or read book Assessing and Managing the Ecological Impacts of Paved Roads written by National Research Council and published by National Academies Press. This book was released on 2006-01-22 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: All phases of road developmentâ€"from construction and use by vehicles to maintenanceâ€"affect physical and chemical soil conditions, water flow, and air and water quality, as well as plants and animals. Roads and traffic can alter wildlife habitat, cause vehicle-related mortality, impede animal migration, and disperse nonnative pest species of plants and animals. Integrating environmental considerations into all phases of transportation is an important, evolving process. The increasing awareness of environmental issues has made road development more complex and controversial. Over the past two decades, the Federal Highway Administration and state transportation agencies have increasingly recognized the importance of the effects of transportation on the natural environment. This report provides guidance on ways to reconcile the different goals of road development and environmental conservation. It identifies the ecological effects of roads that can be evaluated in the planning, design, construction, and maintenance of roads and offers several recommendations to help better understand and manage ecological impacts of paved roads.
Download or read book Service Life Economic Analysis for Pavement Design and Maintenance Planning written by and published by . This book was released on 1997 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper describes a methodology to perform service life economic analysis for cost-effective management of roads and highways. The methodology predicts service life pavement condition and quantifies agency costs, user costs, and benefits. Condition-responsive maintenance intervention policies include asphalt resurfacing, concrete overlays and reconstruction. Reasonably good agreement is shown with the vehicle operating cost stream predicted by the World Bank's HDM-III program for typical asphalt pavement sections. Case studies are presented to illustrate the use of service life benefit and cost analysis to develop maintenance work programs and to prioritize competing alternatives for a new urban road. The paper also presents an example of the user cost methology implemented for network-level pavement management applications in Mexico. For the covering abstract of this conference see IRRD number 872978.
Download or read book Pavement Service Life Estimation and Condition Prediction written by Jianxiong Yu and published by . This book was released on 2005 with total page 200 pages. Available in PDF, EPUB and Kindle. Book excerpt: Remaining service life estimation and pavement condition prediction are two essential functions of Pavement Management Systems. Survival curves are often developed to obtain remaining life of a pavement family at network level. Regression equations are often developed to predict future pavement condition at project level. The two objectives of this study are: (1) To develop the Cox Proportional Hazard model to analyze the effects of influential factors on pavement remaining life; (2) To develop linear mixed effects prediction model to improve the condition prediction accuracy for individual pavements. In this study, by specifying pavement condition rating (PCR) of 70 as the terminal pavement status, survival curves were developed based on historical PCR data using Cox Proportional Hazards method. Further, the estimated service lives of pavements were obtained from these survival curves. As an example, the survival data of asphalt overlays on flexible pavements in Ohio were analyzed for this study. The effects of influential factors such as structure thickness, climate, traffic loading, and pavement conditions prior to repair on pavement service life, were assessed. The results show that the Cox Proportional Hazards model is applicable in estimating the effects of influential factors on pavement service life. The service life obtained from this study can be used to assist in pavement rehabilitation decision-making, overlay design, and budget allocation. Condition prediction of individual pavement is usually required in project-level management and is often based on adjusting corresponding pavement family deterioration trend. This study proposes using the Linear Mixed Effects Model (LMEM) method to predict future conditions of a specific pavement section by a weighted combination of the deterioration trends of the family average and that of the specific pavement. The weights are determined by the number of historical condition measurements available and the variations of the measured historical conditions of the specific pavement. The results of the LMEM showed significantly better accuracy in predicting specific pavement conditions compared with two commonly used adjustment methods, which use the latest condition measurement to adjust family model for individual pavement. The findings in this study show that the LMEM is useful for project level pavement condition prediction.
