Biomineralization of Plastic Waste to Improve the Strength of Plastic-Reinforced Cement Mortar
(2021-04)The development of methods to reuse large volumes of plastic waste is essential to curb the environmental impact of plastic pollution. Plastic-reinforced cementitious materials (PRCs), such as plastic-reinforced mortar ... -
Hydraulic Analysis at the Interface of the Yellowstone River and the Huntley, Montana Irrigation Diversion Fish Bypass
(Montana State University, 2021-11)The nature-like bypass channel built to allow fish to circumvent the Huntley Diversion Dam on the Yellowstone River was constructed in 2015. A project was commissioned in 2019 to determine the effectiveness of the bypass ... -
In Situ Effective Snow Grain Size Mapping Using a Compact Hyperspectral Imager
(2021-02)Effective snow grain radius (re) is mapped at high resolution using near-infrared hyperspectral imaging (NIR-HSI). The NIR-HSI method can be used to quantify re spatial variability, change in re due to metamorphism, and ... -
Hydraulic characterization and removal of metals and nutrients in an aerated horizontal subsurface flow “racetrack” wetland treating oil industry effluent
(Elsevier, 2021-07)Constructed wetlands (CW) are an attractive technology due to their operational simplicity and low life-cycle cost. It has been applied for refinery effluent treatment but mostly single-stage designs (e.g., vertical or ... -
Variation of Small-Strain Shear Modulus of Unsaturated Silt under Successive Cycles of Drying and Wetting
(2020-07)A new framework is developed to extend an existing small-strain shear modulus (𝐺max) model to determine 𝐺max of unsaturated silty soils along different paths of the soil water retention curve (SWRC) including the scanning ... -
Kinetics of Calcite Precipitation by Ureolytic Bacteria under Aerobic and Anaerobic Conditions
(2019-05)The kinetics of urea hydrolysis (ureolysis) and induced calcium carbonate (CaCO3) precipitation for engineering use in the subsurface was investigated under aerobic conditions using Sporosarcina pasteurii (ATCC strain ... -
Using hyperspectral plant signatures for CO2 leak detection during the 2008 ZERT CO2 sequestration field experiment in Bozeman, MT
(2010-03)Hyperspectral plant signatures can be used as a short-term, as well as long-term (100-year timescale) monitoring technique to verify that CO2 sequestration fields have not been compromised. An influx of CO2 gas into the ... -
Practical Guidelines for Estimation of Rest Area Use on Rural Interstates and Arterial Highways
(2012-01)Rest areas perform a critical role in the highway network. These areas provide passenger vehicle occupants and heavy vehicle operators with an opportunity to use a restroom, walk around, stop for a meal, sleep for a period ... -
Remote Sensing of Weather and Road Surface Conditions
(2013-01)Advances in road weather sensing technologies have made noninvasive road weather sensors a valuable component in many intelligent transportation systems (ITS) applications. This study investigates the reliability of using ... -
Traffic Operations on Rural Two-Lane Highways: A Review on Performance Measures and Indicators
(2018-05)Two- lane highways constitute a large proportion of the highway system in the United States, particularly in rural areas. Performance evaluation on those highways is the basis for planning, upgrade, and improvement programs. ... -
Performance measures on two-lane highways: Survey of practice
(2018-11)Two-lane highways constitute a significant component of the highway system and serve an essential function for the movement of people and goods. The Highway Capacity Manual is primarily used for operational analysis on two ... -
Examining the Effect of Speed and Roadway Geometry on Crash Experience along a Rural Corridor
(2014-03)This paper presents a current investigation into crash experience along a 15.7-mile rural corridor in southwest Montana with the aim of better understanding crash causal factors along the corridor. The study utilized ten ... -
Prioritization Scheme for Proposed RWIS Sites: Montana Case Study
(2017-08)A model for prioritization of new proposed environmental sensor station (ESS) sites is developed and presented in this paper. The model assesses the overall merit (OM) of a proposed ESS site as part of a Road Weather ... -
Perceived Risk of Phoning While Driving: A Case Study from Jordan
(2015-10)The use of mobile phones while driving is banned in most countries since it impairs driving performance and is believed to increase crash risk. The aim of this research is to identify the prevalence of phoning while driving ... -
Traffic Safety Along Tourist Routes in Rural Areas
(2016-01)Little is known about the safety of tourist drivers in the United States. Most domestic studies have focused on traffic deaths and injuries of U.S. citizens traveling abroad and cite factors such as driving on the left, ... -
Safety Effects of Road Geometry and Roadside Features on Low-Volume Roads in Oregon
(2016-01)Crashes are random events and can occur at any location along a roadway. On roadways with high traffic volumes, the more frequent occurrence of crashes permits the direct identification of high-frequency crash locations ... -
Measuring Performance on Two-Lane Highways: Empirical Investigation
(2017-01)This paper presents an empirical investigation into several performance measures for operational analysis on two-lane highways. The performance measures investigated are average travel speed, average travel speed to free-flow ... -
Motorists' voluntary yielding of right of way at uncontrolled midblock crosswalks with rectangular rapid flashing beacons
(2018-07)This article presents an investigation into the motorists' voluntary yielding behavior to bicycles and pedestrians at uncontrolled midblock crosswalk locations. Two study sites in the state of Montana with light emitting ... -
Detection of Pathogenic and Non-pathogenic Bacteria in Drinking Water and Associated Biofilms on the Crow Reservation, Montana, USA
(2018-07)Private residences in rural areas with water systems that are not adequately regulated, monitored, and updated could have drinking water that poses a health risk. To investigate water quality on the Crow Reservation in ... -
Pressure gradients in a steeppass fishway using a computational fluid dynamics model
(2017-11)The Alaska steeppass is a fishway used commonly in the eastern United States and in remote locations, and is an example of the many configurations of fishways, ladders, bypass channels and other structures intended to ...
