The Saskatchewan Ministry of Highways and Infrastructure (SMHI) recently commissioned a Reclaimed Asphalt Pavement (RAP) Management and Application Study to identify and optimize areas of use for RAP materials. With depleting aggregate sources across areas of the province, RAP is considered a valuable recycled material with surplus quantities generated from construction and maintenance activities across the province’s highway network. RAP materials generated from SMHI contracts typically are either:
One of the outcomes of the study was the generation of a RAP management plan. The RAP management plan was developed by considering current uses of RAP in Saskatchewan at a consultant, contractor, and agency level; and best practices in other jurisdictions. This paper will present the RAP management and re-incorporation processes developed in the form of an optimization table, and decision flowcharts for use during the design, construction, and operations phases of the roadway.
