Regina Bypass Project's Innovative Asphalt Pavement Structures

Currently in progress, the “Regina Bypass” highway project involves the construction of approximately 45 km of a new four-lane highway (greenfield), the rehabilitation of more than 18 km of Highway 1 (brownfield), and 5 km of reinforcement works on an existing section. The project is being realized using a “Design-Build-Finance-Operate-and-Maintain” (DBFOM) approach and it will be operated by the concessioners group until late October 2049. Taking into account the specific physical and climatic constraints involved, as well as the concession’s duration, flexible pavements have been designed using several innovative concepts such as a mechanistic pavement design approach to the structural pavement design, the use of engineered asphalt mixes, the use of on-site recycling process for existing sections, and the installation of performance monitoring stations. This article provides a summary of the numerous laboratory tests required for the study of the engineered asphalt mix formulations specifically developed for this project, and it describes the follow-up program that will measure their performance with time.
