Filter by Keyword50 report(s) found with maintenance in the keywords field Regular inspection and maintenance of culverts are critical to ensure the safe functioning of transportation infrastructure systems, preventing injuries, loss of life, and significant financial damage. Various state departments of transportation (DOTs) and the American Association of State Highway and... 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... Gravel road safety is a crucial area of road safety since gravel roads represent a substantial proportion of the entire nation's roadway network. Also, gravel roads pose inherent hazards that are otherwise absent in paved roads. Nonetheless, research related to assessing road conditions for county gravel... Tracks are a critical and expensive railroad asset, requiring frequent maintenance. Railroads companies often rely on the accurate localization and identification of the track anomalies that could cause serious damage to infrastructure, environment, and the traveling public. However, the deployed method... Snowplow trucks serve a crucial role in winter maintenance activities by removing, loading, and disposing of snow. An effective performance monitoring and analysis process can assist transportation agencies in effectively managing the snowplow trucks and maintaining normal functioning of roadways. Previous... Achieving and maintaining public transportation rolling stocks in a state of good repair is very crucial to providing safe and reliable services to riders. Transit agencies that seek federal grants must also keep their transit assets in a state of good repair. Therefore, transit agencies in small urban... Bridge inspection data is an essential step in the bridge asset management operation and the bridge management system. As such, a reliability-based, holistic framework was proposed to effectively collect reliable data and perform data fusion and information fusion of sensory data used for element-level... This report presents the feasibility of a novel anchor system that mitigates the end-peeling of carbon fiber reinforced polymer (CFRP) sheets used for strengthening reinforced concrete beams. Contrary to conventional anchoring methods, CFRP sheets are embedded inside the pre-grooved concrete and covered... Reinforced concrete bridge wall piers constructed using older codes perform inadequately during strong earthquakes; deficiencies include short reinforcement lap splices, insufficient steel reinforcement ratios in the longitudinal and transverse direction, and inadequate seismic detailing. Three half-scale... In Wyoming, most county paved roads were built decades ago without following minimum design standards. However, the recent increase in industrial/mineral activities in the state requires developing an efficient pavement management system (PMS) for local paved roads. The new PMS which is currently being... |
