Includes bibliographical references (pages 161-164).Executive summary -- Introduction and background -- Experiment design -- Project and participation requirements -- Project recruitment and approval process -- Construction guidelines -- Data collection -- Plans and recommendations for pavement instrumentation -- Status of test sites -- Key products and benefits -- Summary -- References -- Bibliography.The Specific Pavement Studies (SPS) portion examines specially constructed pavements, which will help develop better understanding of the effects on performance of a few targeted factors not widely covered in General Pavement Studies (GPS). SPS also explores options for construction of new pavements, the application of maintenance treatments to existing pavements, and the rehabilitation of distressed pavements. This report summarizes the status of SPS as of June 30, 1992.

Long-term pavement performance information management system : five year report / by Hadley, William O.; Copeland, Charlie R.(Charlie Reagan)(CARDINAL)323078; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 72-75).SHRP-LTPP Information Management System (IMS) -- Data/information sources -- Data types and elements and sources of the data -- Equipment and operations -- References.This report describes the information management system within SHRP-LTPP to service the NPPDB and the quality assurance checks that verify the presence, reasonableness, accuracy, and validity of the data prior to incorporation into the NPPDB. The National Pavement Performance Database (NPPDB) houses many types of data including inventory, materials characterization, longitudinal profile, deflection, cross profile, distress, friction, maintenance, rehabilitation, climate, and traffic. The report discusses data types and elements in detail and notes data sources. Equipment and operations of the NPPDB are described, as well as NPPDB products.Performed under contract no.

SHRP-LTPP materials characterization : five-year report / by Hadley, William O.; Groeger, Jonathan L.; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (pages 170-174).Introduction -- Field material sampling and testing -- Laboratory materials handling and testing -- Appendices -- References.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.

SHRP-LTPP general pavement studies : five-year report / by Hadley, William O.; Strategic Highway Research Program (U.S.)(CARDINAL)298325; Texas Research and Development Foundation.(CARDINAL)323071;
Includes bibliographical references (pages 78-79).Introduction -- Description of SHRP regions -- GPS sampling templates -- Project recruitment -- Project approval -- Project status classifications -- SHRP-LTPP status (July 1992) -- Data collection -- Early available data sources -- Data modules activities -- Products -- Recommended activities in GPS -- References.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.

Early analyses of LTPP general pavement studies data : executive summary / by Rauhut, J. Brent(James Brent),1928-(CARDINAL)311464; Darter, Michael I.(CARDINAL)286899; Brent Rauhut Engineering, Inc.(CARDINAL)311391; ERES Consultants, Inc.(CARDINAL)286907; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Executive summary -- Limitations resulting from data shortcomings -- Evaluation of the AASHTO flexible pavement design equation -- Evaluation of the AASHTO rigid pavement design equation -- Improved design equations: Applications and limitations -- Evaluation of the 1993 overlay design equations -- Sensitivity analyses and results -- Recommendations for future analyses.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.This effort was funded by SHRP contract,

Asphalt concrete synthetic reference sample program and the LTPP asphalt concrete core proficiency sample program / by Steele, Garland W.(CARDINAL)768876; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Part I: Summary of research -- Part II: List of participants -- Initiating letters and worksheets -- Part III: Research report.All laboratories conducting tests for the Long-Term Pavement Performance (LTPP) program were required to be accredited by the American Association of State Highway and Transportation Officials (AASHTO) Accreditation Program (AAP). AAP includes site inspections of equipment and procedures, and participation in applicable proficiency sample testing. A few critical LTPP tests were not addressed fully by the AAP, and the LTPP decided to conduct supplemental testing. The asphalt concrete synthetic reference sample program and the asphalt concrete core proficiency sample program were among the supplemental programs approved for implementation. In the first of these two programs, a set of four specimens was circulated to all participating laboratories for testing in accordance with specified parameters. In the second program, two sets of cores (five per set) were shipped to the laboratories. Twenty-four laboratories participated in either one or both programs. Worksheets, supporting data, analyses, final comments, and conclusions are presented. A complete set of proficiency sample statements are provided.

Assessing the results of the Strategic Highway Research Program. by United States.Federal Highway Administration.(CARDINAL)139839; Strategic Highway Research Program (U.S.)(CARDINAL)298325;
Includes bibliographical references (page 21)."In 1995, shortly after the 5-year Strategic Highway Research Program (SHRP) concluded and during the early stages of the national program to encourage the implementation of SHRP products, the Transportation Research Board (TRB) SHRP Committee suggested that a benefits-versus-costs study of SHRP be undertaken. The committee members felt that an objective assessment of the project and the products was needed, to determine if the investment had been a wise one. This report summarizes the results of that study, which was conducted during 1996 and 1997"--P. ii.
