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

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 ... -
Evaluation of High Performance Residential Housing Technology
(University of Waterloo, 2008-09-11)The energy consumption of residential buildings in Canada accounts for 17% of national energy use (Trudeau, 2005). Production homes represent a considerable portion of new housing. In an effort to reduce the national ... -
Evaluation of Mechanical and Durability Properties of Concrete with Recycled Materials for its use in Interlocking Concrete Pavement
(University of Waterloo, 2022-08-17)The use of coarse recycled concrete aggregates (CRCA) in concrete as a replacement for natural aggregate (NA) has recently sparked a lot of attention. The use of CRCA is gaining acceptance as more research into its performance ... -
Evaluation of persulfate for the treatment of manufactured gas plant residuals
(University of Waterloo, 2013-02-01)The presence of coal tars in the subsurface associated with former manufactured gas plants (MGPs) offers a remediation challenge due to their complex chemical composition, dissolution behaviour and recalcitrant characteristics. ... -
Evaluation of Potential Health Risks from Microplastics in Drinking Water
(University of Waterloo, 2021-05-03)Microplastics have been detected, often abundantly, in freshwater environments over the past decade. While understanding of the ecological health implications of microplastics in aquatic environments has advanced considerably, ... -
