How can we design better, cost-effective roads by comparing concrete, asphalt, and composite roads for Hamilton's infrastructure?
Project Description: Hamilton is evaluating the long-term benefits of different pavement cross sections enhance its infrastructure. The challenge is to compare the costs, durability, and sustainability of using concrete, composite, and asphalt pavements across various road projects. We want to understand the trade-offs in using each material, especially with soft subgrades, and incorporate modern solutions like geogrid technology to reduce excavation and improve soil stability. Additionally, we aim to explore how the use of different pavement make ups can impact excess soil and the amount of excavation required to make structurally sound pavements. Additionally we want to see how the Excess Soils Regulations (O.Reg 904/19) and the use of Reclaimed Asphalt Pavement (RAP) can shape future road construction practices. Students can help by analyzing data on current road conditions, replacement costs, and lifecycle assessments to recommend the best materials for different projects.
