Filter by Keyword45 report(s) found with construction in the keywords field Connections between precast concrete elements must be able to withstand significant stresses and deformations in earthquakes. The grouted splice sleeve (GSS) connector is being considered for connecting footing, column, and cap beam elements in accelerated bridge construction (ABC). There are limited... Grouted Splice Sleeve (GSS) connectors are being considered for connecting bridge columns, footings, and pier caps in Accelerated Bridge Construction (ABC). A repair technique for precast reinforced concrete bridge column-to-footing and column-to-pier cap joints constructed with GSS connectors has been... Conventional test methods for roadway compaction cover less than 1% of roadway; whereas, intelligent compaction (IC) offers a method to measure 100% of a roadway. IC offers the ability to increase compaction uniformity of soils and asphalt pavements, which leads to decreased maintenance costs and an... To date, BIM (Building Information Modeling) is not widely utilized in infrastructure asset management. Benefits achieved through implementation in vertical construction, however, suggest that BIM represents significant opportunity for gains in process, material, and economic efficiency throughout infrastructure... 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. |
