Public education and outreach activities increase the effectiveness of work law enforcement does to prevent large truck-involved crashes. This demonstration project was conducted through two components including a primary education program and a complimentary education program designed to be executed...
The Americans with Disabilities Act (1990) mandates that paratransit services should be comparable to fixed-route systems. However, with only 5% of the population utilizing public transit, this comparison does not adequately highlight the disparities between persons with disabilities and those without....
Potholes are a significant pavement distress compromising safety and causing costly damage. They result from pavement deterioration due to aging, weather, and traffic overloads, with the Mountain Plains region particularly affected due to freeze/thaw cycles. Timely identification and repair of potholes...
This report discusses the benefits of full-scale pavement testing and the use of accelerated pavement testing (APT) to collect pavement performance data under actual experimental conditions. The report highlights the development and operation of road test tracks, such as the Minnesota Road Research Project...
Escherichia coli (E. coli) is often used as an indicator organism to quantify the microbial safety of natural water resources. E. coli in stormwater runoff can cause serious health risks in natural water bodies. Conventional stormwater best management practices are generally not effective at removing...
This report presents the behavior of reinforced concrete beams retrofitted with carbon fiber reinforced polymer (CFRP) sheets and ultra-high performance concrete (UHPC) jackets in a multi-hazard environment. Following the procedural protocol of a published standard, the beams are cyclically loaded under...
In recent years, major initiatives have been taken to replace non-renewable materials with environmentally friendly and sustainable ones. The present study was undertaken to apply a scalable process for laboratory production of cellulose nanofibers (CNF) and to evaluate the feasibility of using the produced...
Ultra-high-performance concrete (UHPC) is distinguished by its superior mechanical and durability properties. These characteristics are attained through a precise mixture design that includes a low water-to-cement ratio, high fineness supplementary cementitious materials (SCMs), and steel fibers. This...
Pavements in cold regions of the United States undergo significant accumulation of snow and ice on their surfaces during the extended winter season, leading to reduced skid resistance and increased traffic crashes. Deicers, such as sodium chloride, calcium chloride, and magnesium chloride, have been...
A research section was built within a major highway to compare the performance of different geosynthetic-reinforced pavement systems. The first test section contained no geosynthetic reinforcement. The second section was reinforced with a layer of geogrid. In the third test section, geotextile was placed...
