Recycled Concrete Aggregates

The recycled aggregate is used as soon as it is processed. Recycled concrete currently supplies about 5% of aggregate use. The bulk of recycled aggregates – about 68 % – is used as road base. The remainder is used for new concrete mixes (6%), asphalt (9 %) and fill. Recycling concrete features both cost savings and environmental benefits:

  • Recycled Aggregate - California Recycled Aggregate - California

    Recycled aggregate comes primarily from PCC and AC from road rehabilitation and maintenance, demolition, and leftover batches of AC and PCC. After processing, the rocks retain bits of cement or asphalt. A roadway is built in several layers: pavement, base, and sometimes subbase. The pavement is the surface layer, and is made of PCC or AC.

    Aug 19, 2020 Methodology. Recycled concrete aggregates are generally more porous than the primary coarse aggregates. The main property of pervious concrete is its permeability, so the part of fine aggregate can be reduced and the part of natural aggregate can be replaced with recycled concrete aggregate to enhance permeability without much affecting the strength of the concrete.
