Filter by Keyword54 report(s) found with pavements in the keywords field The feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated in this research. This research was performed in two phases. The first phase consisted of modifying the GLWT to handle 15.2 cm (6 in) cores, developing a laboratory compaction procedure... This project has investigated the performance of the admixtures during and after leaching has occurred. This report presents information in two main areas of investigation. The first is a soil column study to determine downward, one-dimensional solute transport properties and trends of the admixtures... State highway agencies throughout the United States use smoothness specifications to ensure they are providing the public with quality roads. Some state highway agencies even provide monetary incentives to contractors for building smoother roads. The effectiveness of such incentive policies, though... This document is the second in a series of three manuals produced for the South Dakota Department of Transportation. It is intended for use by county superintendents and other county roadway agency personnel within the State of South Dakota for the efficient selection of maintenance, rehabilitation... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to better understand how selecting an Mr value influences the thickness of an asphalt overlay pavement. The objectives of this study were to: 1) investigate the importance of several... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the effect of construction Profilograph Index (PI) values on long-term roughness measurements of concrete pavements. The objectives of this study were to determine if increased... In this research the feasibility of using the Georgia Loaded-Wheel Tester (GLWT) to predict rutting in the laboratory was investigated. The study consisted of modifying the GLWT to handle 15.2 cm (6-in.) cores, obtaining asphalt pavement cores from several test sites throughout Wyoming, collecting rut... This project is ongoing at Colorado State University to study road dust suppressants with the objective of measuring the relative effectiveness in this semi-arid region as well as any water quality degradation resulting from this usage. Five test sections are being evaluated in this research project... This report describes a study jointly conducted by the University of Wyoming and the Wyoming Department of Transportation to examine the factors influencing the determination of a subgrade resilient modulus value. The objectives of this study were to first, investigate the importance of several fundamental... This study examines consolidation of road services by local governments, and explores the optimal mix of roads for rural counties. A methodology for measuring economies in the provision of local road services is presented. This methodology is unique in two ways; 1) it better accounts for relevant variables... |
