Filter by Keyword53 report(s) found with construction in the keywords field In this study, the current SDDOT Road User Cost methodology and associated unit costs were evaluated and changes were implemented to the methodology to allow for a more complete analysis that aligns with the needs of each department and their use of RUC. The methodology was used to construct a worksheet... The use of self-consolidating concrete (SCC) for the manufacture of precast structural elements provides the benefits of increased rate of production, reduced labor needs (safety), and enhanced product quality. The same benefits apply to cast-in-place construction, especially with closely spaced reinforcing... Untreated native soil with high swell potential has been identified by the Colorado Department of Transportation as one of the major contributing factors in the development of premature longitudinal cracking and other pavement distresses in Colorado (Ardani et al. 2003). Unique regional factors such... The utilization of recycled glass in highway applications has been occurring over the past couple of decades. In recent years, the discovery of several economic and environmental benefits could increase the use of recycled glass in highway construction, making the evaluation of the engineering properties... Animal-vehicle crashes are a concern for many areas of the country but are a particular concern for rural areas such as Wyoming. While there is considerable literature available on the effectiveness of various animal-vehicle countermeasures, such as fencing and signing, there is currently little quantifiable... This paper evaluates the impact of various I-15 reconstruction closure scenarios on the travelers in the Ogden area. The purpose of the research was to investigate the impact of the scenarios and facilitate decisions about future maintenance of traffic during the reconstruction. This paper presents preliminary results of the VISUM Online validation. It compares traffic conditions estimated by VISUM Online to measured data. The results show that VISUM Online produces comparable traffic measures. This report is Phase II of a previous MPC research project (MPC 02-136) that developed a computer model using a transient, two-dimensional finite volume approach to mathematically describe the thermal response of asphalt pavements due to thermal environmental conditions on an hourly basis. The main objective... Transportation is a vital national need and one of the areas of increased employment opportunities. Fostering student interest in transportation and transportation related areas of study is vital to our nation's future work force, and these arenas are rapidly becoming a popular career choice for undergraduate... This report describes the results of examining the effects of weather exposure conditions on the connection details of the open deck timber trestle bridge. As an exploratory experimental study, the time dependent mechanical effects of moisture, temperature and humidity on a particular connection detail... |
