Get PriceThe recycled mixture is usually used as a base (or subbase) layer in the pavement system with an overlay of asphalt concrete (AC) to protect the cold recycled base. A case study of cold recycling in Toronto (Canada) presented a comparison between the conventional rehabilitation techniques and the cold recycling [1] .

Get PriceRecycled Asphalt Pavement (RAP) is the term given to removed and/or processed materials containing asphalt and aggregates. These materials are generated when asphalt pavements are removed for construction, resurfacing, or to obtain access to buried utilities.
