TRS: Recycled Materials in Unbound Aggregate Base Layers in MinnesotaStatus: CompleteReport Date: 09/12/2016 Summary: The purpose of this Transportation Research Synthesis (TRS) is to provide an overview about the use of recycled materials in the base layers of pavements, and the design of these layers when using recycled materials. While the primary focus is on local streets and county roads, attention was also given to pavements constructed by state highway agencies. This TRS has at least two intended audiences: the Local Road Research Board (to aid in directing further research that may be needed) and engineers at local highway and street agencies (to assist in their immediate needs for guidance regarding recycled materials in maintaining their road networks).
