Over the years, the industry has expressed growing interest in the idea of recycling. Worldwide, the trend has been confirmed for several reasons:
- Re-use of raw materials: aggregates are not available in sufficient quantities, following the reduction of the number of available quarries operating nationally and internationally.
- Energy savings: fall in energy consumption following reduced operation of aggregate quarries, transport services and lead times.
- Bitumen recycling: aggregates are recycled, but also and above all the bitumen binder contained in asphalt aggregates (AA).
