Prediction Of Four-Days Soaked California Bearing Ratio (Cbr) Values From Soil Index Properties, Pascal Ambrose, Siya P. Rimoy Dr

Tanzania Journal of Engineering and Technology (TJET)

California Bearing Ratio (CBR) laboratory testing is the conventional method for determining soaked strengths of pavement subgrades. The test requires careful preparation of soil samples followed by four days of water soaking before penetrating the samples using a standard plunger at prescribed rates to set depths. When the number of samples becomes large the determination of soaked CBR values becomes cumbersome as the test is laborious and time consuming. This study aimed at establishing an alternative way of determining soaked CBR by developing a model that would be used for estimating soaked CBR of fine- and coarse- grained soils without …

Establishing Safe Operating Speeds For Autonomous Vehicles: A Case Study From The Automated Skyway Express In Jacksonville, Florida, Andrew Loken

Department of Civil and Environmental Engineering: Dissertations, Theses, and Student Research

Autonomous vehicles (AVs) differ significantly from traditional passenger vehicles in both their behavior and physical characteristics. As such, the validity of the guidance provided in the Manual for Assessing Safety Hardware, Second Edition (MASH 2016) is questionable in AV applications. Impact conditions specified in MASH 2016 are inextricably linked to the traditional vehicles underlying the estimates. For AV applications, conditions must be estimated from the ground up, stepping outside the guidance of MASH 2016. Herein, a method for evaluating existing infrastructure to support AV traffic is proposed. The method integrates traditional structural analyses with unconventional methods of estimating impact conditions. …

From Attitude To Satisfaction: Introducing The Travel Mode Choice Cycle, Jonas De Vos, Patrick A. Singleton, Tommy Gärling

Civil and Environmental Engineering Faculty Publications

Many studies analysing the relationship between attitudes and travel behaviour have found that travel attitudes have an important impact on travel mode choice. More recently, studies focusing on how people experience travel have shown that travel satisfaction is influenced by the chosen travel mode. The desire and intention of using a travel mode – which can be considered as important predictors of mode choice – have, however, received limited attention. Furthermore, existing studies mostly have a narrow scope and lack integration of the above constructs. In this paper, we introduce the travel mode choice cycle (TMCC), a comprehensive model aiming …

Effect Of Degradation Environment And Relative Humidity On Fracture Of Cement, Patience L. Raby

Civil Engineering ETDs

Concrete serves in all forms of humidity conditions (arid climates to submerged conditions) and can be exposed to many different forms of degradation. To better understand the effects that degradation and humidity have on concrete as a composite, the effects on cement alone must first be better understood. This research aims to examine the significance of degradation (calcium leaching or sulfate attack), in addition to relative humidity, on cracking and fracture behavior of cement. Flexure and fracture tests were performed on cement exposed to varying periods of each form of degradation as well as various humidities. Samples were exposed to …

Detection And Tracking Of Pedestrians Using Doppler Lidar, Xiaoyi Peng, Jie Shan

Lyles School of Civil Engineering Faculty Publications

Pedestrian detection and tracking is necessary for autonomous vehicles and traffic manage- ment. This paper presents a novel solution to pedestrian detection and tracking for urban scenarios based on Doppler LiDAR that records both the position and velocity of the targets. The workflow consists of two stages. In the detection stage, the input point cloud is first segmented to form clus- ters, frame by frame. A subsequent multiple pedestrian separation process is introduced to further segment pedestrians close to each other. While a simple speed classifier is capable of extracting most of the moving pedestrians, a supervised machine learning-based classifier …

A Conceptual Framework For Phase-Dependent, Composite Flood Risk Index (Fri) Curves Based On The Relationship Between Temporal Probability Of Flood Occurring (Ph) And Flood Vulnerability Index (Fvi) Along With Maps Of Fvi Within The Amite River Basin Based On The August 2016 Flood., Austin S. Guerin Mr.

LSU Master's Theses

Efforts directed at determining community vulnerability to flooding are limited and only include economic (dollar damages) and public safety impacts and do not consider the phase dependency of the system, i.e., pre-, during- and post-storm, both critical shortcomings for more broadly assessing community risk and developing comprehensive plans and mitigation strategies. This thesis first develops a framework based on a Flood-Vulnerability Index (FVI) approach and then demonstrates its usefulness, at the census tract level of detail, for three parishes in the Greater Baton Rouge, LA area, based on the August 2016 flood. FVI’s indicators are multidimensional and phase dependent: “Pre-Flood” …

Evaluation Of Fine And Coarse Graded Asphalt Mixes, Md Mehedi Hasan

Civil Engineering ETDs

During the last 20 years, asphalt pavements were built in New Mexico (NM) and around the country using mostly Superpave coarse graded mixes as opposed to fine graded mixes. This is because coarse mix uses larger aggregates with good interlocking and requires less asphalt binder than a fine mix, while both mixes fulfill the Superpave criteria. Recently, it was observed nationally that the Superpave coarse graded mixes have good field rutting performances but poor cracking performances. It is hypothesized that fine graded mix can help improve pavement cracking performances. The idea is, the fine mixes would have less air voids …

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Because of their extensive coverage, marine low clouds greatly impact the global climate. Presently, the response of marine low clouds to the changes in atmospheric aerosols remains a major source of uncertainty in climate simulations. One key contribution to this large uncertainty derives from the poor understanding of the properties and processes of marine aerosols under natural conditions and the perturbation by anthropogenic emissions. The eastern North Atlantic (ENA) is a region of persistent but diverse subtropical marine boundary layer (MBL) clouds, where cloud albedo and precipitation are highly susceptible to perturbations in aerosol properties. Here we examine the key …

Compliance With Hand Sanitizer Quality During The Sars-Cov-2 Pandemic: Assessing The Impurities In An Ethanol Plant, Gabriel Cohen, Nathan Kreutzer, Katie M. Mowat, Ashraf Aly Hassan, Bruce I. Dvorak

Department of Civil and Environmental Engineering: Faculty Publications

Using alcohol-based disinfectants is an effective method for preventing the spread of COVID-19. However, non-traditional manufacturers of alcohol-based disinfectants, such as ethanol plants, need to undergo additional treatment to curb their impurities to limits set by the Food and Drug Association (FDA) to produce alcohol-based disinfectants. To transform them to disinfectant-grade alcohol, 17 process streams in a dry-mill ethanol plant were analyzed to determine the quality parameters for acetaldehyde, acetal, propanol, methanol, and water, including chemical oxygen demand, total suspended solids, and nutrients. Results suggest that the process stream generated by the distillation column requires further treatment because the acetaldehyde …
