Book Synopsis SHRP-LTPP Data Analysis Studies by : William O. Hadley
Download or read book SHRP-LTPP Data Analysis Studies written by William O. Hadley and published by . This book was released on 1994 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: One of the principal objectives of the Strategic Highway Research Program Long-Term Pavement Performance (SHRP-LTPP) study was the development of a comprehensive electronic media database for housing pavement performance data covering a wide range of conditions and service life factors. The database was structured to address pavement management and engineering design issues. The extent and scope of information contained within the LTPP database and Information Management System (IMS) also provides the resources not only to evaluate or revise existing design equations but to develop new ones. During the first 5 years of the SHRP-LTPP program, most issues have been addressed in various data analysis studies. Data analysis studies concerning load equivalency factors, materials and construction variability, rutting initiation studies, and the results of the specific SHRP-LTPP data analysis contracts are presented in subsequent sections of this report. These studies represent initial efforts in pursuit of LTPP goals and operatives and are based primarily on early General Pavement Studies data.

This book was released on 1994 with total page 92 pages. Available in PDF, EPUB and Kindle. Book excerpt: The General Pavement Studies (GPS) examine selected in-service pavements and compile data to form a comprehensive national pavement performance database that meets the objectives of the Strategic Highway Research Program's Long-Term Pavement Performance (SHRP-LTPP) project. The purpose of this report is to document the development, evolution, and current status of GPS. Data collection criteria were developed for each of the various data elements in GPS, including traffic, skid resistance, deflection, profile, distress, environment, material properties, and climate. Some data were collected by states, others by the SHRP regional offices.

Download or read book Long-Term Pavement Performance (LTPP) Program Specific Pavement Studies (SPS) written by Gonzalo R. Rada and published by . This book was released on 2018 with total page 306 pages. Available in PDF, EPUB and Kindle. Book excerpt: Pavement preservation represents a proactive approach to maintaining and extending the lives of existing highway pavements. At the heart of the preservation decision-making process is pavement performance. This report documents the recommended experimental design for the LTPP SPS-11 Asphalt Concrete (AC) Pavement Preservation Study as well as the various elements required for its successful implementation. However, the recommended experiment will not be implemented under the LTPP program, but the experiment and this project report can be adopted and adapted by interested highway agencies to achieve the stated benefits, and consequently the impetus for publication of the report. The underlying concept of the experiment is to apply the same preservation treatment, at different times, on the same pavement structure to determine the effectiveness of a single application of a treatment as a function of pavement condition and time. This experiment is designed to answer the question on when is the best time to apply a preservation treatment on AC pavements. It will also enable development and implementation of important pavement preservation products and tools, such as addition of pavement preservation considerations to the AASHTO Mechanistic-Empirical Pavement Design Guide and associated software.

Book Synopsis SHRP-LTPP Materials Characterization by : William O. Hadley
Download or read book SHRP-LTPP Materials Characterization written by William O. Hadley and published by . This book was released on 1994 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Strategic Highway Research Program (SHRP) developed two materials characterization programs: one for field sampling, and another for laboratory testing. The SHRP field materials sampling and laboratory materials testing program encompassed all 50 states; 10 Canadian provinces; and Puerto Rico. This report documents the development and execution of these programs for both the General Pavement Studies (GPS) and the Specific Pavement Studies (SPS). These topics are described separately here, although they are linked inherently. Suggestions are given for future materials characterization within the Long-Term Pavement Performance program as it continues under the Federal Highway Administration.
Book Synopsis LTPP Specific Pavement Studies (SPS) Materials Action Plan Final Report by : Peter N. Schmalzer
Download or read book LTPP Specific Pavement Studies (SPS) Materials Action Plan Final Report written by Peter N. Schmalzer and published by . This book was released on 2010 with total page 228 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the activities and accomplishments of the Long-Term Pavement Performance (LTPP) program Materials Action Plan (MAP). The MAP was initiated in August 2004 to improve the extent and amount of materials data to characterize the pavement structure of test sections at LTPP Specific Pavement Study (SPS) -1, -2, -5, -6, and -8 experimental sites. The success of the MAP can be attributed to the cooperation and efforts of participating highway agencies, leadership of the Federal Highway Administration (FHWA) LTPP team, and technical input from LTPP's Transportation Research Board Committee and Expert Task Groups. The MAP was also supported by the efforts of the FHWA LTPP team of technical services, regional support, and laboratory contractors. Through this effort, the amount and quality of available materials data greatly increased. Data from tests not previously performed were added, results from aging materials tests were obtained, corrections were made to some pavement structure information from new field investigations, and to the extent possible, previous data deficiencies were corrected. This report documents the planning, execution, and outcomes of this highly successful activity.

Download or read book Long-term Pavement Performance Information Management System Data Users Reference Manual written by and published by . This book was released on 1997 with total page 66 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Long-Term Pavement Performance Information Management System (LTPP IMS) Data Users Reference Manual contains an overview of the LTPP program and the data available to researchers. LTPP is a 20-year study of pavements to improve design, rehabilitation, and maintenance practices. This document is intended to assist researchers in understanding the data that are currently available for General Pavement Studies Experiments and how to obtain it. The General Pavement Studies are a group of asphalt concrete (AC) and portland cement concrete (PCC) experiments using in-service pavements. In addition to materials test results for the pavement sections, data on pavement history, maintenance, and rehabilitation are stored in the IMS. Information on distress, transverse profile, cross profile, pavement deflection, and traffic is collected on a routine basis and added to the data base regularly. The manual includes information on the quality control process.

This book was released on 1994 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: This summary presents the results of the first data analyses of the Strategic Highway Research Program Long-Term Pavement Performance (LTPP) project. Data analyzed included information collected up to 1992. These analyses included: 1) developing a data analysis plan, 2) receipt and processing of data into suitable data bases for analysis and conducting statistical evaluations of the data bases, 3) using the LTPP data to evaluate the American Association of State Highway and Transportation Officials (AASHTO) design equations, 4) conducting sensitivity analyses to identify the independent variables that have significant impacts on pavement performance and to quantify the relative impact of each, and 5) using the experience gained from these early data analyses to recommend concepts for future data analyses.
