High-Performance Pavements: A Focus on Self-healing Asphalt Technologies

Cracking is one of the most prevalent deterioration modes of flexible pavements in North America. At intermediate temperatures, long-term exposure to traffic loading leads to fatigue microcrack damage, which causes a decline in the pavement's mechanical properties. Thus, research and development on innovative materials with self-healing properties has become a growing area of transportation research in recent years. Asphalt cement was first observed to display this type of behaviour in the 1960s when it was found that the introduction of rest periods could extend the life of the asphalt samples during laboratory testing. Modern researchers have begun to draw inspiration from other branches of materials science and the natural world in order to apply the concepts of self-healing materials to asphalt mixtures. This paper presents a state-of-the-art of self-healing ability of asphalt cement to heal fatigue damage as well as current research efforts to characterize the self-healing capabilities of asphalt pavements. The continual development and successful implementation of high-performing self-healing asphalt materials will ensure that pavements constructed can withstand the challenges of the future while increasing the economic, environmental and societal value of Canada's road network.
