Filter by Keyword45 report(s) found with construction in the keywords field A new method for building seismically resilient bridges is proposed using accelerated bridge construction (ABC) methods. The hybrid two-column bridge bent consists of post-tensioned precast concrete columns with a buckling restrained brace (BRB) as an external energy dissipation device. The design of... The use of precast concrete in bridge construction has been abundant in recent years because of its efficiency and superior quality control. Precast components are connected at the bridge site to reduce construction time and traffic disturbance. The Grouted Splice Sleeve (GSS) connection provides good... Due to the short construction season in Wyoming, contractors must complete many transportation projects on a tight schedule. Unfortunately, contractors often cannot create accurate schedules considering logical work ordering, reasonable productivity, and weather events. Inaccurate baseline schedules... This project aims to using eye-tracking technology to optimize work zone safety. First, a systematic literature review was conducted to present the background of its application in construction safety. In total, 81 publications were screened from Web of Science (WoS), Scopus, and American Society of... A mechanical bar splice, also known as bar coupler, is an alternative to the traditional lap splicing to connect bars in reinforced concrete (RC) structures. Even though mechanical bar splices can be used as new precast column connections to accelerate bridge construction (ABC), the use of bar couplers... Precast concrete construction has been proven to be very efficient in bridge engineering, especially in accelerated bridge construction (ABC), where precast concrete components are connected to save time and minimize disruption of traffic. Post-tensioned (PT) concrete structural elements, when combined... Local governments have an immediate need for low life-cycle cost bridge replacement alternatives. Knowledge of available alternatives and construction planning processes hold potential for South Dakota local governments to replace more structurally deficient local bridges with limited funds. Through... The Rocky Mountain Region has experienced considerable difficulty because of alkali-silica reaction (ASR) in concrete construction. Wyoming Department of Transportation was successful in using recycled concrete aggregate (RCA) on Interstate I-80 with limited ASR damage. Reusing concrete from demolition... This report discusses the design and implementation of surcharging technology and the required laboratory, field, and engineering evaluations. It is hoped that such information will provide a more consistent and technically defensible rationale for deploying this technology on highway projects constructed... Construction of highways usually requires large areas of land disturbance, which may result in accelerated soil erosion. The stormwater runoff from highway construction sites typically contains a large amount of fine particles that are difficult to remove using conventional best management practices.... |
