Recycling aggregate into the asphalt hot mix and new concrete is being identified as the highest economic value of the recycled aggregate. The objective of this paper was to investigate the value of recycled Portland cement concrete (PCC) and reclaimed asphalt pavement (RAP) rubble as engineered structural granular aggregate. The value of RAP as a granular base is significant when viewed in the context of the whole roadway structure. The cost (in Canadian dollars) for new raw materials to construct roadways is between $16.75 and $35.00 per square meter without a drainage layer. Savings of $3.96 per square meter are shown when RAP is used as a structural granular layer, up to 24% of the total material cost. In comparison, $1.22 per square meter of savings is experienced when RAP is used in HMAC, up to 6% of the total material cost. Similar values can be seen with PCC being used in the granular structure, particularly when used as a drainage layer. The cost for new raw materials to construct roadways is between $30.60 and $39.00 per square meter with a crushed rock drainage layer. As recycled PCC aggregates are engineered into the granular structure, $3.96 per square meter of savings is shown when PCC is used in the base layer; and $9.00 per square meter of savings is identified when PCC is used in the drainage layer. The drainage layer is critical to extending the life of a roadway by removing moisture and deep structural strains, particularly in newly developed areas in low lying areas.
