Advanced Self-Healing Asphalt for Roads of the Future
FY 2019-20 · 2020-03-25
Summary
It is well-known that asphalt pavements in cold regions such as Canada are exposed to number of environmental stresses such as thermal fatigue cycles and low-temperatures which result in different modes of distresses most commonly cracking. In addition, repeated application of traffic loads on flexible pavement induces structural cracking known as bottom-up fatigue distress. Considering that cracked pavements are more susceptible to water seepage and frost action, it is crucial to reverse the cracking process through use of self-healing bituminous materials in order to extend the service life of the infrastructure, reduce the amount of Greenhouse Gas emissions and decrease the energy usage. Improving the self-healing properties of asphalt binder and Hot Mix Asphalt (HMA) through innovative techniques and novel applications is still at emerging stage. This project will investigate the rheological properties and healing characterization of nano-clay modified asphalt binder and performance testing of HMA specimens containing nano-clay modified asphalt binder.

Description (French)
La chose est bien connue : dans les régions froides comme le Canada, la chaussée en asphalte est exposée à de nombreuses contraintes environnementales comme les cycles d’agression thermique et la chute des températures à l’origine de diverses détériorations, la plus fréquente étant la fissuration. Une circulation intense et récurrente sur la chaussée malléable engendre aussi des dommages structuraux du bas vers le haut, attribuables à la fatigue. Crevassée, la chaussée est plus sensible aux infiltrations d’eau, donc à l’action du gel. Pour renverser le processus, il faut colmater les brèches avec des matériaux bitumineux expansibles qui prolongeront la vie utile des infrastructures routières, freineront les dégagements de gaz à effet de serre et réduiront la consommation d’énergie. Rehausser les propriétés du liant de l’asphalte et du bitume mélangé à chaud au moyen de techniques innovantes et de nouvelles applications n’en est qu’à ses débuts. Le projet s’attardera aux propriétés rhéologiques et au pouvoir de réfection du liant d’asphalte enrichi de nanoparticules d’argile et comprendra des essais pour vérifier la performance des mélanges chauds de bitume contenant un tel liant.
Expected Results
In the short term, anticipated outcomes will be strengthened collaborations across industry, academia, and government to support research excellence. In the medium term, anticipated outcomes will be the development of new and potentially disruptive technologies with collaborators.
Expected Results (French)
À court terme, les résultats prévus sont des collaborations renforcées dans l’ensemble de l’industrie, du milieu universitaire et du gouvernement afin d’appuyer l’excellence en recherche. À moyen terme, les résultats prévus sont le développement de technologies potentiellement perturbatrices avec des collaborateurs.

Program Name (French)
Programme de collaboration en science, en technologie et en innovation – Fonds d’idéation
Program Purpose
The Ideation Fund is intended to encourage, test and validate transformative research ideas generated by teams of NRC scientific personnel and external collaborators with complementary capabilities, acting as a demonstration phase for a continually-evolving suite of research and development (R&D) deliverables at the NRC. The fund supports exploratory research through two mechanisms: the New Beginnings Initiative and the Small Teams Initiative.
Program Purpose (French)
Le Fonds d’idéation vise à encourager, à mettre à l’essai et à valider les idées de recherche transformatrice des équipes scientifiques du CNRC et des collaborateurs externes dotés de capacités complémentaires. Il servira ainsi de plateforme de démonstration d’une série de produits livrables en matière de recherche-développement (R-D) en constante évolution au CNRC. Le Fonds appuie la recherche exploratoire au moyen de deux mécanismes : l’Initiative « Nouveaux débuts » et l’Initiative « Petites équipes ».
