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 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: 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.

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.
