Book Long term Pavement Performance Information Management System Data Users Reference Manual

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.

Download or read book LTPP written by and published by . This book was released on 1998 with total page 16 pages. Available in PDF, EPUB and Kindle. 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.

Available in PDF, EPUB and Kindle. Book excerpt: Sponsored by the Highway Division of ASCE; Long-Term Performance Program of the Federal Highway Administration. This collection contains papers from the International Contest on LTPP [Long-Term Performance Program] Data Analysis 1998-1999. This competition involved university students in the analysis of data in the LTPP database. Topics include: effect of locked-in curvature on portland cement concrete pavement; evaluation of a pavement performance prediction model using LTPP data; prediction of pavement performance?a neural network approach; and effectiveness of preventative maintenance strategies for asphalt concrete pavements based on LTPP distress data.

Book Long Term Pavement Performance Pavement Loading User Guide  LTPP PLUG

Download or read book Long Term Pavement Performance Pavement Loading User Guide LTPP PLUG written by Olga I. Selezneva and published by . This book was released on 2013 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This guide addresses the selection and use of axle loading defaults for Mechanistic-Empirical Pavement Design Guide (MEPDG) applications. The defaults were developed based on weigh-in-motion (WIM) data from the Long- Term Pavement Performance (LTPP) Special Pavement Study (SPS) Transportation Pooled Fund Study (TPF). The guide consists of two parts. The first part provides guidelines for selecting and using LTPP SPS TPF axle loading defaults with the MEPDG and DARWin-ME software. These defaults provide a source of axle loading information for pavement analysis for locations where site-specific axle load spectra are not available. The second part of the guide provides practical guidelines that States and LTPP can use to generate additional MEPDG traffic loading defaults based on their own WIM data or for specific analysis purposes. In addition, this guide contains an operator's manual that supports the use of the LTPP PLUG software. This software helps users select site-specific or default axle loading conditions from its traffic loading library and produces axle load distribution input files for use with the MEPDG or DARWin-ME software. The software can be used to store, view, and group multiple normalized axle load spectra (NALS) and to develop MEPDG inputs and defaults using agency-provided data.

Book Long term Pavement Performance Inventory Data Collection Guide

Download or read book Long term Pavement Performance Inventory Data Collection Guide written by A.L. Simpson and published by . This book was released on 2006 with total page 103 pages. 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.

Book Long term Pavement Performance Maintenance and Rehabilitation Data Collection Guide

Download or read book Long term Pavement Performance Maintenance and Rehabilitation Data Collection Guide written by Amy L. Simpson and published by . This book was released on 2006 with total page 239 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This document provides guidelines and forms for documenting maintenance and rehabilitation treatments on test sections in the Long-Term Pavement Performance (LTPP) program and is an update to chapters 6 and 7 of the 1993 version of the LTPP Data Collection Guide. The terms maintenance and rehabilitation are used within the LTPP program to classify how various treatments which alter a test section's structure are documented in the database. This is an important distinction, since classification of some of these treatments may differ from highway agency terminology. For example, thin overlays that some agencies may classify as maintenance are classified within the LTPP program as rehabilitation, since the data forms for overlays of any thickness are the same."--Technical report documentation page.
