Abstract :

The research in the area of pavement materials, engineering and design has significantly evolved in the last two to three decades due to environmental, economic and societal reasons. This research became highly oriented towards finding solutions to address these challenges though the increase of recycling, the reduction of energy consumption and CO2 emissions, the use of alternative materials and other innovations. The Canadian researchers have significantly contributed to these international research efforts through several research projects. The main purpose of this paper will be to present an overview of some research projects on sustainable pavement materials conducted by the researchers of the Centre of Pavement and Transportation Technology of the University of Waterloo in the last few years. The paper will also briefly discuss the current and the future research of the team in this area. One of the main research directions was that of the optimization of the use of recycled materials in the different construction applications. The paper will focus on research projects involving four different types of recycled materials: Reclaimed asphalt shingles, recycled concrete aggregates, recycled roofing shingles and recycled rubber tires. The research on the development of solutions to optimize the energy consumption during the process of manufacturing of bituminous materials was also of great importance for the CPATT researchers. Solution for warm and half-warm asphalt mixes and cold in-place recycling will then be presented. Each solution will be presented briefly and the main results of each projects will discussed.
