NRRA: Improve Material Inputs Into Mechanistic Design Properties for Reclaimed HMA & Recycled Concrete Aggregate (RCA) Roadways

Status:  Complete
Report Date:  08/04/2021


The proposed study will help to establish a database for RAP And RCA materials` characteristics including resilient modulus (Mr), CBR/UCS, gradations along with construction specifications. Thus, this would lead to more consistent material input and specifications between NRRA agencies. Once a database of material characteristics is established, the cost involved in acquiring and testing field samples for new design is reduced/refined. The outcome of this research in the form of a pavement design specification could be immediately implemented by the department of transportations (DOTs) of states participating in NRRA.
