Book SHRP LTPP General Pavement Studies

Download or read book SHRP LTPP General Pavement Studies written by William O. Hadley and published by Strategic Highway Research Program (Shrp). 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.

Book Early Analyses of LTPP General Pavement Studies Data

Download or read book Early Analyses of LTPP General Pavement Studies Data written by Brian M. Killingsworth and published by . This book was released on 1994 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this volume is to provide statistical data that may be used to characterize the nature of the data in the various data sets. The specific data sets are the General Pavement Studies (GPS)-1, GPS-2, GPS-3, GPS-4, and GPS-5 data. Data were obtained from the Long-Term Pavement Performance (LTPP) Data Base (also referred to as the LTPP Information Management System).

Book SHRP LTPP Overview

Download or read book SHRP LTPP Overview written by William O. Hadley and published by National Research Council. This book was released on 1994 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report provides an overview of the first 5 years of the Strategic Highway Research Program Long-Term Pavement Performance (SHRP-LTPP) program. The background, LTPP history, activities and approaches, and decision-making processes of the program are detailed. Included are summaries of the studies initiated for general and specific pavement types, the characterization of pavement materials, monitoring activities, the LTPP database and Information Management System, data analysis, traffic data collection and analysis, as well as a summary of the contributions made by international participants. The general LTPP program is described and the expected results, products, and benefits are also outlined.

Book Early Analyses of LTPP General Pavement Studies Data

Download or read book Early Analyses of LTPP General Pavement Studies Data written by J. Brent Rauhut and published by Strategic Highway Research Program (Shrp). 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.

Book SHRP LTPP Monitoring Data

Download or read book SHRP LTPP Monitoring Data written by Gonzalo Rada and published by . This book was released on 1994 with total page 120 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the LTPP monitoring data collection activities for inclusion in the National Pavement Performance Database. The pavement condition monitoring data include identification of surface distress, profile measurements, deflection testing results, and surface friction measurements. The report also describes traffic, climate, maintenance, rehabilitation, and seasonal monitoring and data collection. Other results and products of the 5-year pavement condition monitoring activity are listed.

Book SHRP LTPP Data Analysis Studies

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.

Book SHRP LTPP Materials Characterization

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 Highway Research

Download or read book Highway Research written by Institution of Civil Engineers (Great Britain) and published by Thomas Telford. This book was released on 1991 with total page 468 pages. Available in PDF, EPUB and Kindle. Book excerpt: The level of research activity in the highway sector as a whole has declined precipitously in recent decades, whilst the challenges facing US state highway agencies have escalated. As a result, a Strategic Highway Research Program - SHRP) was initiated to establish collaboration with research bodies tackling similar highway problems in countries worldwide. This collection of reports from around the world presents SHRP`s progress towards providing research-based new products from which the international highway engineering community may benefit. SHRP concentrates on six high-priority research areas: asphaltic materials; pavement performance; cement and concrete; maintenance cost effectiveness; concrete bridge component protection systems and the chemical control of snow and ice.
