RCA was collected from a crushing plant which is 35 km areaway from the batching plant. All the aggregates were pre-processed in terms of grading size. Two different size grades were present: 4.75–9.5 mm and 9.5–19 mm. The reference aggregate was the natural aggregate which has the similar size grade as hard rock.

The major environmental concerns of aggregate production are outlined in the Table. Stage in aggregate processing. Major environmental impacts. Quarrying and processing raw material. Scarring of landscape. Dust and noise. Some sources are in areas of outstanding natural beauty. Proximity to major centres of population.
