Escherichia coli (E. coli) in stormwater is a significant environmental concern as it indicates potential contamination from fecal matter, raising risks for both human and aquatic health. Conventional stormwater best management practices are generally not effective at removing E. coli from stormwater...
The determination of bed shear stress plays a pivotal role in understanding the fluid dynamics in both natural and engineered channels. The commonly employed logarithmic law provides a mathematical formula to compute the bed shear stress in open-channel flows. However, its applicability in flow through...
Fibers are used in an asphalt mix to improve its durability and resistance against distresses, such as rutting and cracking. Consequently, accurate rheological and performance characterization of asphalt binders and mixes containing fibers is of vital importance. With increased concerns over the environmental...
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...
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...
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...
The study aimed to understand the impacts of extreme climatic conditions such as prolonged droughts and intense precipitation due to climate change on the resilience of civil infrastructures like embankments. The knowledge of unsaturated soil mechanics and soil chemistry is integrated to determine the...
The South Dakota Department of Transportation (SDDOT) has been using the Ohio Highway Department’s (OHD) moisture-density curves for compaction quality control of granular materials. However, the OHD curves were not developed for granular materials, and their use was found to result in inconsistencies...
The relationship between soil erosion rate and bed shear stress is an important problem in sediment transport and scour. However, obtaining reliable measurements of soil erodibility is challenging, both in the field and in the laboratory. The objective of this study is to investigate an experimental...
According to the 2017 ASCE Infrastructure Report Card (ASCE 2017), 9.1% of the U.S. bridges are structurally deficient. The majority of deficient bridges are in service on low-traffic volume roads, and these bridges should be replaced or repaired for public safety in a timely manner. As an alternative...
