Filter by Keyword44 report(s) found with pavements in the keywords field In an effort to prevent pumping and reduce premature pavement failures due to infiltrated water, UDOT has contracted Utah State University (USU) to evaluate the hydraulic conductivity (k) of Utah's dense graded untreated base course material. The hydraulic conductivity describes the ease with which water... Some North Dakota counties are facing a shortage in quality gravel. Other counties may experience the same problem in the near future. Gravel pits in the state are scarce and counties consume substantial amounts of gravel for a large portion of their roads. Obtaining gravel from distant sources leaves... 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... |
