ABSTRACT: Polyurethane resin has several useful and unique applications in civil engineering works. The material characteristics of different types of polyurethane resin are reviewed in this article. A discussion of the basic formulation of the resin components and associated civil engineering applications is also presented. For clarification and illustration purposes three case studies showcasing the application of polyurethane in Alberta Transportation highway projects are presented.
