Evaluating the Effect of a Self-Healing Elastomer on the Self-Healing Properties of Asphalt Cement
(University of Waterloo, 2020-09-25)Asphalt pavements exhibit an interesting behaviour when the traffic loading is removed. The chemical structure of asphalt cement lends itself to the ability to heal damage and improve the longevity of the pavement. This ... -
Evaluating the Effectiveness of Cities Working With Ridesourcing Companies
(University of Waterloo, 2021-01-07)The process of using an application or web-based platform to hire a person with their personal vehicle to transport someone to their destination is also known as ridesourcing; and this is a new form of transportation ... -
Evaluating the Effectiveness of Liquid Organic Anti-icing Chemicals for Winter Road Maintenance
(University of Waterloo, 2015-07-24)Over five million tons of road salts are applied in Canada every winter to keep users of roads, parking lots and side walks safe. While effective for snow and ice control, salts at high concentrations are detrimental to ... -
Evaluating the Effects of Grain Size and Divalent Cation Concentration on the Attenuation of Viruses and Microspheres through Crushed Silica Sand
(University of Waterloo, 2006)Over the last decade in North America, an increasing number of microbiological drinking water regulations have been used to manage groundwater resources that are potentially influenced by surface water. Regulations such ... -
Evaluating the Effects of Spalling on the Capacity of Reinforced Concrete Bridge Girders
(University of Waterloo, 2011-09-01)Corrosion of the reinforcing steel is a primary deterioration mechanism for reinforced concrete bridges. Heavy use of de-icing salts is believed to be a major contributor in Ontario to severe girder soffit spalling in ... -
Evaluating the effects of strain selection on the attenuation of Bacillus subtilis spores through saturated porous media
(University of Waterloo, 2013-10-02)Increasingly stringent water quality regulations concerning microbiological parameters govern the use of groundwater resources that are vulnerable to mixing with surface waters. These drinking water sources are at higher ... -
Evaluating the Retrofit of Highway Bridges Using Fluid Viscous Dampers
(University of Waterloo, 2012-01-23)Highway bridges function as the arteries of our society. Hence, it is essential that they remain operational following an earthquake. Unfortunately, a significant number of bridges worldwide, including in Canada, were ... -
Evaluating Thermal Regime of Cold Region Roads for Climate Change Adaptation
(University of Waterloo, 2020-04-07)Nearly a quarter of the Northern Hemisphere is underlain with permafrost, of which discontinuous permafrost is most sensitive to the temperature of its surrounding. Climate change and the implementation of infrastructure ... -
Evaluating Tire Pressure Control System to Improve Productivity and Mitigate Pavement Damage
(University of Waterloo, 2008-09-12)The introduction of the use of Tire Pressure Control Systems (TPCS) to improve the productivity of the Canadian trucking industry is gaining momentum. The imposition of seasonal load restrictions (SLR) on the thaw-weakened ... -
Evaluating Unbonded Concrete Overlay for Usage on Ontario Residential Streets
(University of Waterloo, 2018-01-22)Composite pavements have become increasingly common in North America, these pavements usually result from the rehabilitation of Portland cement concrete (PCC) pavements. When a PCC pavement reaches close to the end of its ... -
Evaluation and Calibration of Pedestrian Bridge Standards for Vibration Serviceability
(University of Waterloo, 2017-08-14)An increase in the use of lightweight materials and emphasis on architecturally appealing designs has resulted in lively pedestrian bridges. A prominent example for this is the serviceability failure of the London Millenium ... -
Evaluation and Quantification of Engineered Flocs and Drinking Water Treatability
(University of Waterloo, 2008-08-28)Jar tests are performed to simulate full-scale pre-treatment and particle removal processes. Operators typically conduct them in an effort to attempt alternative treatment doses and strategies without altering the performance ... -
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 ... -
An Evaluation of Alternatives for Enhancing Anaerobic Digestion of Waste Activated Sludge
(University of Waterloo, 2010-04-30)Waste activated sludge (WAS) is one of the largest by-products of biological wastewater treatment. Anaerobic digestion of WAS is beneficial for several reasons. In an ever increasingly energy conscientious world the ... -
Evaluation of Cold Weather Performance of Rubber Modified Asphalt Placed in Ontario
(University of Waterloo, 2014-07-29)Canada has close to 900,000 km of roads, which are key to supporting the Canadian economy as they enable for efficient transportation of goods and services. The Canadian road network should be well maintained and perform ... -
Evaluation of Different Techniques for Repair of Shear-span Corrosion-Damaged RC Beams
(University of Waterloo, 2013-04-25)Deterioration of reinforced concrete structures due to reinforcement corrosion is a serious problem that faces concrete infrastructure worldwide. Effect of the rebar corrosion in the shear span on the structural behaviour ... -
Evaluation of Early In-Place Concrete Performance Based on Test Results of Cores and Cylinders
(University of Waterloo, 2018-08-21)The evaluation of in-place concrete performance, relating to its mechanical properties, continues to remain a challenge for engineers and researchers, but is essential for determining the safety of a structure and from the ... -
