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.

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.

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.

Book excerpt: This report documents the early observations from the Long-Term Pavement Performance (LTPP) Specific Pavement Studies (SPS) conducted as part of the LTPP Program Data Insight, which was conducted to identify initial findings from the test sections established for this program. Comparisons of performance trends were made to evaluate both the distinctions between the various rehabilitation treatments and the performance of the individual treatments themselves based on their condition prior to the treatment. Most of the rehabilitation strategies are still performing adequately after 3 to 4 years of service, as should be expected.

Available in PDF, EPUB and Kindle. Book excerpt: The primary purpose for this data collection guide is to provide a uniform basis for data collection during long-term monitoring of the performance of pavement test sections under study by the Long-Term Pavement Performance (LTPP) Program. It is a revision to chapter 2 of the 1993 LTPP Data Collection Guide. Inventory data include that data necessary to: 1) identify the test section, 2) describe the geometric details of its construction and the material properties of its structural constituents, and 3) identify construction costs and costs of subsequent maintenance and repair before the long-term monitoring effort. These data are intended to describe the pavement test section at the time the section was included in the LTPP study.

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.
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.

Download or read book The Long Term Pavement Performance Program Roadmap written by United States. Federal Highway Administration. Pavement Performance Division and published by . This book was released on 1995 with total page 43 pages. Available in PDF, EPUB and Kindle. Book excerpt: The goal of the ongoing, 20-year long-term pavement performance (LTPP) studies is to give State and Provincial transportation departments - the owners and customers of the LTPP program - the information and tools they need to build and maintain longer-lasting pavements. The Roadmap charts a course to the program's near-term and longer term destinations, which are based on the products needed by State and Provincial highway agencies today. The Roadmap was developed with input from all of the partners, which include State and Provincial highway agencies, the American Association of State Highway and Transportation Officials (AASHTO), the Transportation Research Board, industry, academia, and FHWA. The LTPP program is a dynamic process; as needs and priorities shift, the Roadmap and data analysis plan will be adjusted accordingly.
