Europe: BAM breaks new ground in asphalt recycling

BAM breaks new ground in asphalt recycling with success at two test sections of road in the Netherlands.

Bam laid  an asphalt road surface consisting of up to 93% recycled material – more than three times the level in current practice.

An innovative mixture was used to produce an asphalt road surface consisting of up to 93% recycled material

The mixture is produced at a temperature of around 105?C. In addition to the high re-use value, this results in an energy and CO2-reduction of approximately 30%, reports Aggregates Business Europe.

BAM used Sylvaroad RP1000 Performance Additive, made by Arizona Chemical. The road surfaces in both test sections consist of double-layer porous asphalt (very open asphalt concrete) that provides a noise reduction of 7dB. The test sections are part of a European demonstration project, on which BAM has worked for over three years.

BAM can apply road surfaces of at least 80% recycled material on a large scale. Compared with current percentages of re-use in road surfaces, which consist of up to 30%, this method achieves a breakthrough in the production of sustainable asphalt.

The performance of the asphalt mixture and of the recycled raw materials has been tested intensively. Sylvaroad is a rejuvenator on the aged bitumen.  In every respect, it appears that the recycled raw materials and the asphalt produced from them are qualitatively at least equivalent to traditionally produced road surfaces, and often even better.
