Abstract
From an environmental point of view, recycled aggregates can be an alternative for natural ones and the environmental footprint of RAC can be limited by using high grade RA. Furthermore, the delivery distance of NA is the key parameter in assessing the environmental impacts of RAC, compared to NAC. Results showed that global warming indicator impact is greater for NAC, compared to RAC with 50% of RA, provided that NA delivery distance exceeds 50Â km, which is the case in Paris' region. With 20% of substitution rate, high-grade RA improve all environmental impacts of RAC, except Waste, compared to NAC.
