The main goal of this research project is to reduce the rate of occurrence of these distresses by designing and developing improved asphalt binder and asphalt mixtures appropriate for St. John’s environmental and loading conditions. The project will develop recommendations on specifications for asphalt binders, modifiers and asphalt mixtures to enhance the rutting and moisture resistance of pavement.
Two primary objectives of this undertaking are (1) to determine whether ore recovery along pit walls can be increased by replacing and/or augmenting current pit wall stability assessments involving two-dimensional static methods with three-dimensional deformation analyses and (2) to differentiate pit wall deformations associated with stress relaxation from those associated with failure. Three-dimensional deformation analyses using traditional and/or semi-custom constitutive models calibrated against (a) laboratory testing data and (b) in-situ monitoring data will be used in this evaluation.
Deliberate massive sand influx used to increase oil recovery from shallow heavy oil resources ultimately results in low oil recovery. This means 85-95% of oil would remain unrecovered during the co-production of oil and sand process, which is referred to as Cold Heavy Oil Production with Sand (CHOPS). In this project, we looked at the possibility to enhance oil recovery using CO2 injection.
In cold regions, freezing temperatures impede construction activities or put them on hold until warmer seasons, as concreting activities under such conditions are quite challenging. This leads to considerable socioeconomic losses. This research will advance the current knowledge on cold weather concreting, which is a critical issue for Canada and other cold regions.
The aim is to improve a software tool for reliability-based quantitative analysis of dents (QuAD) in pipelines developed by Enbridge. QuAD is a tool used to predict the failure for dented pipelines, so that the deteriorated pipeline segments can be reliably identified for excavation to avoid failure. The critical concern with the current QuAD tool is its inefficiency due to long analysis time and the potential room for accuracy improvement.
The aim of this project is to prepare carbonaceous adsorbents from Moringa stenopetala seed husks for removal of contaminants such as heavy metals and dyes from aqueous solution of commercial interest. The proposed project will examine the developed carbonaceous adsorbents to determine their adsorption capacity, kinetics, selectivity for specific contaminants, at different operating conditions. This research will help partner organization to convert the available agri-waste at their site to valuable products, i.e., to develop adsorbents for commercialization in water treatment applications.
Healthy and sustainable housing is a critical social determinant of health and well-being. In Indigenous communities, decades of ineffective government housing and land policy have created abysmal, often culturally inappropriate housing conditions. Through partnership with First Nations, we will explore and uncover solutions to answer these questions: What if we could co-create Indigenous homes to be sources of health, wealth and connection in tune with culture and the environment? How would that change things for future generations?
From December 2021 all the construction projects in Quebec should follow new Draft Regulations Amending Quebec Construction Code. This research investigated the impact of the implementation of section 3 of the new code which relates to the envelope thermal resistance calculation by considering thermal bridges. During phase one the calculation method will be applied for the most common construction details of the building envelopes in Quebec.
The goal of the Dissolvable Glass Technology research project is to develop new glass technologies and products to reduce the cost and environmental impact in the utility, forestry, and oil and gas sectors. It has been said that we are ‘entering the age of glass’, and we aim to explore the numerous and varied possibilities where dissolvable glasses can be utilized. However, to achieve these glass technologies, fundamental glass research must be performed in three key areas: mechanical properties, thermal behaviour and dissolution behaviour.
Large amounts of sewage sludge (SS) have been generated yearly by municipal wastewater treatment plants (WWPs), which entail huge operational expenses and advanced treatments, and the final disposal of biosolids in agricultural applications is reduced because of the potential environmental risks (e.g., heavy metals and emerging contaminants) associated with biosolids applications.
