MacRebur manufactures polymer blends from engineered recycled plastics to extend or modify the bituminous binder in asphalt mixtures. Produced under strict quality control, these blends are created by mixing plastic waste to form unique products. MacRebur products are added directly to the asphalt production facility, similar to fibers or pigments. They decompose completely and homogenize within the asphalt binder during hot mix asphalt manufacturing, ensuring that mixing times and temperatures are typically not altered. The finished asphalt conforms to EN13108 standards, maintaining high quality and compliance.

MR8 uses and applications
The MR8 is manufactured from a blend of recycled polymers and is designed to expand the bituminous binder in asphalt mixtures, reducing the volume of bitumen required. MR8 is intended to replace unmodified bitumen at a lower cost while also reducing CO2 emissions and minimizing the use of fossil fuel-derived resources.

MR8 technical data
Asphalt mixtures produced with MR8 have been extensively tested to ensure continued compliance with all relevant local specifications. MR8 is designed to be added directly to the mixer without the need for temperature adjustments during mixing or laying. It is also compatible with most Warm-mix Asphalt (WMA) technologies, further reducing CO2 emissions and fuel consumption. Typical dosages range from 5-10% of the bitumen weight, but higher doses are possible depending on the specifics of the mixture.

Environmental data

MacRebur commissioned Eunomia, an external consultant, to carry out a carbon footprint assessment of MacRebur’s MR8 product. Their model allowed us to make the following statement:

MR8 demonstrates a saving of 1.55 kg CO2e per 1 kg of product used. When used in asphalt at the recommended average dose of 3 kg per ton of asphalt, it saves 4.65 kg CO2e per ton of asphalt produced.

*The above statement has been verified by SGS in accordance with ISO 14064-3:2006.*
