Book excerpt: Established as part of the Strategic Highway Research Program (SHRP) and now managed by the Federal Highway Administration (FHWA), the Long Term Pavement Performance (LTPP) program faces a significant challenge. Over the past decade, the LTPP program has developed a solid knowledge base for understanding how pavements perform. Its challenge throughout its second decade is to build on this foundation--to further the understanding of why pavements perform as they do. To address this challenge, FHWA has initiated several efforts that require the support and active participation of the States and Provinces. The intent of this document is to describe the challenge the LTPP program faces and explain the efforts underway to address this challenge. This document is presented in the following sections: Introduction; The Challenge; Addressing the Challenge; Critical Issues; and Future Opportunities.

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 excerpt: Several important issues concerning the effect of slab support on concrete pavement performance were studied in a National Cooperative Highway Research Program project, "Support Under Concrete Pavements" (NCHRP 1-30). The results were promising, however, the data that were available for analysis were limited. This study was conducted to further field-verify and develop the improved support guidelines proposed in NCHRP 1-30, using the Long-Term Pavement Performance (LTPP) database, in order to establish their practicality and appropriateness for use in concrete pavement design nationwide. This study was also conducted to further field-verify the proposed revised American Association of State Highway and Transportation Officials (AASHTO) performance model to the fullest extent possible using the design, materials, climate, traffic, and performance data available in the LTPP database for General Pavement Section 3 (GPS-3) (jointed plain concrete pavement), GPS-4 (jointed reinforced concrete pavement), and GPS-5 (continuously reinforced concrete pavement). Guidelines, revised on the basis of the results of this field verification study, are presented in the appendix in the form of a proposed addendum to the AASHTO Design Guide. The documentation of these field verification efforts using the LTPP database is provided in this report.

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.

Available in PDF, EPUB and Kindle. Book excerpt: This is the user's guide for the Long Term Pavement Performance traffic quality control (QC) software designed to load, process, and produce reports on monitored traffic data submitted to the LTPP program. It is divided functionally based on the flow of data through the system to ultimately produce a data review report and data for loading into the analysis software. Eight program functions (buttons) are available from the main control panel for use by the program operator as data are loaded, processed, and analyzed for reports. The software uses an ORACLE database to store summaries of data and writes processed data to text files for use in the LTPP traffic analysis software. This version is outdated. The most current version can be obtained from LTPP Customer Support Service Center.

Available in PDF, EPUB and Kindle. Book excerpt: 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.

This book was released on 1994 with total page 114 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this report is to share the experience gained and lessons learned by research staff during early data analyses of the General Pavement Studies (GPS) and to recommend procedures for future analysts. A review of the techniques used is provided. Shortcomings of the Long-Term Pavement Performance (LTPP) Data Base, known at the time of early analyses, are discussed and data base expectations for future analyses were identified. Some interesting and useful distress and roughness prediction models were developed that illustrate the effects of several design variables. Other analytical procedures for developing predictive equations were identified and described, which may be of use in future analyses. Ten techniques used by the research staff for evaluating the American Association of Highway and Transportation Officials (AASHTO) design equations are identified and recommendations for future evaluations provided.

Available in PDF, EPUB and Kindle. Book excerpt: "A set of data collection guidelines has been provided for the collection of all data obtained for the Long-Term Pavement Performance (LTPP) program. These guidelines were provided to the Regional Support Contractors (RSC) to facilitate data collection on a uniform basis. Over time, additional documents were developed providing more specific requirements for the collection of LTPP data. The primary purpose for the various data collection guides is to provide a uniform basis for data collection during long-term monitoring of the performance of pavement test sections under study by the LTPP program initiated under Strategic Highway Research Program (SHRP) and continued under the Federal Highway Administration (FHWA). As methods for collection of the data have changed and improved over the years, the guidelines used in obtaining these data have changed. The objective of this document is not to provide the exact guidelines, but rather to provide references for the guidelines and revisions to those guidelines used in collecting each type of data for LTPP over the lifetime of the LTPP program."--Technical report documentation page.
