View AllThe objectives of this study were to assess geotechnical properties of mine waste amended with fly ash and evaluate reuse of fly ash amended mine waste as road construction material. Three types of fly ash and one type of cement were used as cementitious binder. Natural and synthetic (i.e., laboratory... This Fact Book provides information on transit service availability and cost to help the transit industry in the United States provide efficient and effective service to meet rural community mobility needs. Financial and operating statistics can be used by agency managers, local decision makers, state... The ultimate objective of this project was to develop widely accepted recommendations on self-consolidating concrete (SCC) mixture design for its use in WisDOT bridge projects. This project investigated the effects of material constituents on the material properties of trial SCC mixtures made from precasters... This research attempts to answer the following fundamental questions: What factors does a transit agency use to choose among alternative TOD locations in a transit network, and what is the relative importance of each factor? It aims to develop a decision support framework that can be used by different... The 24/7 Sobriety Program is an intervention strategy mandating that impaired driving offenders remain sober as a condition of bond or pre-trial release. The goal is to monitor the most at-risk offenders in North Dakota and require that these individuals remain sober in order to keep roadways safe from... Concrete bridge decks are directly exposed to daily traffic loads and may experience some surface cracking caused by excessive stress or fatigue accumulation, which requires repair or replacement. Among typical bridges in North America, bridge decks are considered the most expensive component to construct... Prior to this project, The Grand Forks – East Grand Forks MPO and City of Grand Forks were using approximately 150 (38 intersections) of the City's existing traffic detection cameras for traffic data collection. These cameras were set up during Phase I, II, and IIIa of the study. The data reported... A study was conducted to investigate implementation of accelerated bridge construction (ABC) in South Dakota. Accelerated bridge construction is defined as construction practices that employ innovative techniques to reduce on-site construction time and interruption to traffic. The main objective of this... Traffic crashes are a leading cause of death for North Dakota youth. Previous research shows that risk for fatal and serious injury increases by 50% to 70% when occupants fail to use safety restraint systems. In this pilot year of the study, occupant restraint use in traffic crashes was collected to... The high amount of confining lateral steel required by seismic design provisions for rectangular bridge columns can cause steel congestion. The high amount of confining steel may hinder the placement of conventional concrete (CC). Self-consolidating concrete (SCC) eliminates or reduces concrete placement... |
