Investigating Solutions for Self-Healing and Crack Mitigation of Flexible Pavement Materials
(University of Waterloo, 2023-01-23)In Canada, cracking is the most common deterioration mode of flexible pavements that occurs for different reasons such as traffic loading, and low temperature. Moreover, the propagation of cracks can be accelerated by the ... -
Bracing Requirements for Multi-column Systems with Nonuniform Stiffness and Semi-rigid Connections
(University of Waterloo, 2023-01-12)For a structural system consisting of multiple columns, horizontal discrete braces are often used to increase the system's load-carrying capacity by reducing the columns' effective length. Over the past several decades, ... -
An Enhanced Mechanistic Analysis Framework for Designing Resilient Airfield Pavements
(University of Waterloo, 2023-01-05)Changes in climatic conditions can directly impact pavement performance. With alarming temperature records and the increased frequency of extreme weather events, Canadian infrastructure could be at risk if adaptation ... -
Hydrologic Change Detection Modelling Methods for Disturbed Forested Watersheds
(University of Waterloo, 2023-01-02)Decades of paired catchment studies have provided insights on how forests regulate water redistribution following vegetation disturbances such as logging and wildfire. In these settings, changes in runoff characteristics ... -
Analyzing the Competitiveness of Transit-Integrated Ridesourcing Systems
(University of Waterloo, 2022-12-20)Ridesourcing platforms operated by transportation network companies are becoming increasingly popular. Municipal transit agencies have rapidly launched integrated systems with ridesourcing vehicles to extend the reach of ... -
The Impact of Portland Cement on the Performance of Cold In-Place Recycled Pavement
(University of Waterloo, 2022-12-06)In place recycling of existing asphalt pavement is a rehabilitation strategy, which the Ministry of Transportation Ontario (MTO) adopted decades ago. Asphalt emulsion is the most common type of bitumen stabilizing agent ... -
Lightweight Cellular Concrete as Flexible Pavement Subbase Material: Field Performance and Sustainability Study
(University of Waterloo, 2022-12-01)Enhancing the long-term performance of road infrastructure is an important goal for engineers in Canada, especially with changing climatic conditions. This has brought about varying approaches in design and construction ... -
Evaluation of a Novel β-cyclodextrin Functionalized Nano Adsorbent for Removal of Pharmaceuticals
(University of Waterloo, 2022-11-21)β-CD functionalized adsorbents have increasingly been reported for the removal of organic micropollutants. They have been considered attractive due to the hydrophobic cavity of β-CD which provides non-covalent interactions ... -
Transit Benefit Index: A Comprehensive Index for Capturing Externalities in Transit Planning
(University of Waterloo, 2022-09-30)Transportation externalities plague all members of society with delays during travel, as well as healthcare costs associated with crashes, unwanted noise, and air pollutants. While attempts have been made to correct these ... -
Investigating the Corrosion Behaviour of Carbon Black Steel Rebar in Ordinary and Limestone Cements With and Without Blast Furnace Slag
(University of Waterloo, 2022-09-30)Over the years, strange climate patterns have evolved over the globe, raising flags for concerns on the effects of global warming. Cement production contributes to 8% of the global carbon dioxide emissions. Without regards ... -
Testing and Fretting Fatigue Analysis of Bridge Stay Cable Wires at Saddle Supports
(University of Waterloo, 2022-09-26)High-strength steel cables are one of the principal components of cable-stayed bridges. In these structures, the cables transfer the gravitational loads at the deck to the bridge tower structures or “pylons”. Reliable ... -
Anaerobic Biodegradation of Petroleum Hydrocarbons in Powdered Activated Carbon Groundwater Systems: A Modelling Investigation
(University of Waterloo, 2022-09-19)Subsurface contamination by petroleum hydrocarbons (PHCs) is a widespread issue resulting from oil and gas production, distribution, and use. As a result of improved injection methods and particulate materials, injected ... -
Analysis of Slab-on-Grade Floors Subject to Slab-Mounted Jib Cranes
(University of Waterloo, 2022-09-19)Free-standing, foundationless jib cranes mounted directly on unreinforced slab-on-grade floors are a common necessity in industrial settings for material handling purposes. Ensuring that existing slabs can support a jib ... -
Pavement Performance Prediction Using Machine Learning and Instrumentation in Smart Pavement
(University of Waterloo, 2022-09-19)The optimization of pavement Maintenance and Rehabilitation (M&R) planning and costs has been historically proven as a complex task. In recent years, Artificial Intelligence (AI) and Machine Learning (ML) applications in ... -
Biogeochemistry Across Spatiotemporal Scales: The Role of Reactive Interfaces in Modulating Landscape Scale Contaminant Fluxes
