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.

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.

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 Synopsis Guidelines for the Collection of Long-term Pavement Performance Data by : Amy L. Simpson
Download or read book Guidelines for the Collection of Long-term Pavement Performance Data written by Amy L. Simpson and published by . This book was released on 2006 with total page 0 pages. 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.

Download or read book Long-term Pavement Performance Information Management System written by William O. Hadley and published by . This book was released on 1994 with total page 92 pages. 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 Synopsis Long Term Pavement Performance Program Maintenance and Rehabilitation Data Review, Final Report by : Ahmed Abdelazim Eltahan
Download or read book Long Term Pavement Performance Program Maintenance and Rehabilitation Data Review, Final Report written by Ahmed Abdelazim Eltahan and published by . This book was released on 2001 with total page 145 pages. Available in PDF, EPUB and Kindle. Book excerpt: "Since its inception, the Long Term Pavement Performance (LTPP) program has collected maintenance and rehabilitation (M & R) data on all of the test sections included in the LTPP program. To date, there has been no detailed review of the M & R data elements. This report provides a detailed review of the M & R data and presents the findings from that review. A total of 757 test sections have undergone some type of M & R activity. Of these test sections, only 23 anomalies were found. These anomalies consist primarily of sections that have patching recorded in the M & R tables, but no increase in patching area or number in the distress surveys. All of the M & R data tables for these 757 test sections were reviewed for data completeness. For most of these test sections, several fields are missing in almost all of the tables. A detailed list of the missing data fields is included as an appendix to the report. Although it might be difficult to obtain these data for the older M & R activities, an attempt should be made to collect the essential data elements, as a minimum. The distress monitoring data and International Roughness Index (IRI) values were reviewed for those test sections without any known M & R activity. The number of these test sections exceeded 1800. A review of the data from these test sections was completed to identify those sections that may have had some type of M & R treatment, but for which no treatment is recorded in the LTPP database. A total of 275 anomalies of this type was identified. Over 80% of these anomalies were found to be the result of an increase in patching from the distress surveys in the absence of any patching record in the M & R tables."--Technical report documentation p.

Download or read book Gravel Roads written by Ken Skorseth and published by . This book was released on 2000 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this manual is to provide clear and helpful information for maintaining gravel roads. Very little technical help is available to small agencies that are responsible for managing these roads. Gravel road maintenance has traditionally been "more of an art than a science" and very few formal standards exist. This manual contains guidelines to help answer the questions that arise concerning gravel road maintenance such as: What is enough surface crown? What is too much? What causes corrugation? The information is as nontechnical as possible without sacrificing clear guidelines and instructions on how to do the job right.
