Available in PDF, EPUB and Kindle. Book excerpt: "This project was conducted to describe and evaluate the South Dakota Road Profiler for Demonstration Project 72, 'Evaluation of Equipment for Measuring Pavement Roughness and Rut Depth'. The Road Profiler's profile and rut depth performance were evaluated by comparisons to surveys taken with rod and level and the E.W. Face 'Dipstick'. For each of ten sites, the Road Profiler's measurements at 25, 40 and 55 miles per hour were compared to the manual surveys. Spectral analysis and the International Roughness Index were used to compare profile data, while plots and averages were used to compare rut depth data. The rut Profiler's profile and rut depth measurements correlated well with Dipstick measurements. Minor sensitivity to pavement texture was observed. No operational difficulties were encountered"--Technical report documentation page.

This book was released on 1988 with total page 138 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project evaluates the rut-depth-measurement capability of a three-sensor South Dakota Road Profiler (SDRP), which was built in-house in 1990. The study is divided into six components, which include a statistical comparison of mean-rut-depth measurements obtained with the SDRP, a Dipstick Autoread Profiler and 6-ft straightedges; evaluations of repeatability and vehicle-driver-positioning ability; and, studies of the dependency of SDRP-measured rut depth on vehicle speed, acceleration, deceleration and vehicle lateral position relative to the actual rut location.

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.

Book Synopsis Assessment of Virginia's Hybrid South Dakota Road Profiling System by : Kevin K. McGhee
Download or read book Assessment of Virginia's Hybrid South Dakota Road Profiling System written by Kevin K. McGhee and published by . This book was released on 1996 with total page 27 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Dakota Road Profiling (SDRP) systems have been widely sanctioned for use in assessing road roughness and rutting at highway speeds. Traditionally, these high-speed profiling systems have been built around ultrasonic height sensors. More recently, some designs have begun to substitute laser sensors to combat many of the limitations of sound-based equipment. The functional improvements possible with lasers are expensive, however. Whether the potential of lasers for high-speed profiling justifies the great increase in cost was a legitimate question. This report describes the steps that the Virginia Department of Transportation took to address that issue. In general, this research has found that both sensor types are capable of performing very well and with reasonable agreement. Repeatability tests indicated that the roughness indices calculated from laser based profiles are less subject to run-to-run variability than those developed from ultrasonic profiles. Tests to evaluate the effects of vehicle speed and sampling rate on the estimate of roughness have returned less conclusive results. Both tests suggested that the ultrasonic-based data was more highly correlated with the control data (i.e., that based on data collected with the Face Companies' Dipstick R) than the laser-based. The laser data, however, could be shown to be slightly more accurate, on average, than that based on the ultrasonic. Unfortunately, although the performance of the ultrasonic sensors on conventional surfaces has been adequate, their reliability has become a serious concern. In Virginia, humid surveying conditions are often unavoidable and the problem of wet ultrasonics has become more than a simple inconvenience. Hardware reliability may be the most compelling reason to migrate to pure laser roughness measurement. The adoption of only laser-based equipment in future purchases or leases is recommended.

Book excerpt: This project is the first phase of a proposed larger research effort whose goal is twofold: 1) to determine effective guidelines for collecting and processing road profiles; and 2) to determine, insofar as possible, the specific causes of the poor repeatability in the data obtained by the present Kansas Department of Transportation (KDOT) Pavement Management System.
