Filter by Keyword71 report(s) found with performance in the keywords field This project used field and laboratory evaluations to study the possibility of incorporating bottom ash in asphalt mixes. A pavement test section was constructed for the field portion of the project. The laboratory evaluations involved design and accelerated testing of control and bottom ash asphalt... This report examines the coordinated/regionalized transit systems in North Dakota. There has been controversy over the relative benefits of coordinating rural transit systems. Initially, it was expected that coordinated systems would experience lower costs and/or offer increased services. Some regional studies have indicated that coordinated systems do not experience decreased costs... The purpose of this project is to provide state Motor Carrier Safety Assistance Program (MCSAP) personnel with a sufficient understanding of a performance-based system to begin implementing it in their state programs. This paper explores the determination of commercial vehicle driver attitudes and the effect of these attitudes on driving performance, job satisfaction, and turnover. It was hypothesized that if a relationship is found, it may then be worthwhile to select applicants with the highest potential for good... 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 paper presents results of laboratory tests conducted to determine the effects of additives on the stabilization of unpaved road surfaces. Laboratory tests can be an efficient means of determining which additive will best stabilize a given unpaved road surface, but correlation between laboratory... No performance evaluation guidebook existed for rural and small urban transit systems. Therefore, this guidebook is designed to provide transit operators with a tool for evaluating their system's performance. Each transit operator can measure their system's performance against other similar systems in... This report presents a brief historical overview of the development of expansive (shrinkage compensating) concrete. Three Utah Department of Transportation projects using expansive concrete are discussed as to the performance of the expansive concrete. On-site inspections were performed on three projects... The purpose of this paper is two-fold: 1) to develop a conceptual framework which provides a pragmatic justification for being concerned about job satisfaction from a business perspective; and 2) present some empirical evidence resulting from a national study of drivers conducted at the Upper Great Plains... |
