Cette recherche explore l'utilisation des résidus de bauxite, ou boues rouges, comme substitut aux matériaux routiers conventionnels au Québec. En conditionnant le résidu et en optimisant son incorporation dans l'asphalte, les travaux visent à réduire la dépendance aux granulats naturels, à réutiliser les déchets industriels, à diminuer les coûts et à prolonger la durée de vie des routes de six à dix ans.

This research explores using bauxite residue, or red mud, as a substitute for conventional road materials in Quebec. By conditioning the residue and optimising its incorporation into asphalt, the work aims to reduce reliance on natural aggregates, reuse industrial waste, lower costs, and extend road lifespan from six to ten years.

This research investigates how landslides disrupt New Zealand's road network. By analysing past landslides, linking landslide severity to road impacts, and combining these relationships with landslide forecasts, the project aims to predict future road closures, improve emergency planning, reduce community isolation, and enhance public safety during severe weather and earthquakes.

This research develops quality control standards for fibre-reinforced polymer (FRP) bridge reinforcement, a corrosion-resistant alternative to steel. By testing FRP materials under extreme conditions, the work helps make long-lasting, rust-free bridges a reliable construction standard, reducing maintenance costs, extending bridge lifespans, and improving infrastructure resilience in coastal environments.

This research tackles concrete’s carbon footprint by replacing Portland cement with locally sourced natural pozzolans. By calcining and testing South Island geomaterials, the work demonstrates a low-cost, carbon-free alternative that maintains strength and durability while reducing emissions and construction costs.

This research develops an algorithmic framework to proactively bundle small transportation projects, increasing contractor competition and reducing costs. Using a decade of Tennessee DOT data, it identifies optimal project groupings and flags combinations that reduce efficiency. Bundling improves value for agencies, contractors, and taxpayers, addressing significant waste in current procurement systems.

My research uses particle-based Discrete Element Modelling (DEM) to simulate and analyse how masonry structures age, crack, and fail. By accurately replicating real-life damage and strength, DEM provides a powerful tool for predicting deterioration, improving safety, and planning repairs without harming the structure. Future work explores mortar–brick interfaces, joint types, and brick geometry.
