TyreXol™ MMA 30 is our pre-treated rubber powder additive for dry-processed rubberized asphalt. It is manufactured from rubber powder produced after mechanical shredding of end-of-life tyres. The maximum particle size is less than 600 microns.
It uses the so called ECR - Engineered Crumb Rubber pre-treatment / activation technology to control the interaction between rubber and bitumen
TyreXol™ MMA 30 guarantees an improvement in the technical performance of asphalt pavement, as well as an improved sustainability.
The main advantages of using TyreXol™ MMA 30 in asphalt mixes can be summarized as follows:
- Technical
- Extended pavement life
- Increased resistance to cracking and plastic deformation
- Improved fatigue performance compared to conventional mixes
- Economic
- Due to the increased service life of the pavement, reduction in pavement maintenance costs.
- Possibility of designing pavement with reduced thickness while maintaining or improving the performance of the asphalt mix .
- Activated rubber powder is a more economical additive than synthetic polymers used for the modification of asphalt mixes .
- Environmental
- Rubberized asphalts display better sound-absorbing properties, thus lowering the noise level of road traffic .
- El empleo de polvo de caucho activado en mezclas asfálticas supone un compromiso real con la sostenibilidad medioambiental hacia una economía circular, evitando posibles daños derivados de una mala gestión de los neumáticos usados.
- The use of rubber powder in asphalt mixes represents a real commitment to environmental sustainability towards a circular economy, avoiding possible damage caused by poor management of end-of-life tyres.
- A road paved with rubberized asphalt mixtures (1 km long, 10 m wide and 4 cm thick) can add value for between 2,000 and 4,000 end-of life tyres
- Rubberized asphalt containing TyreXol™ MMA 30 can be laid and compacted at significantly lower temperatures than those of conventional mixes (semi-hot mixes), inducing savings in CO2 emissions, as well as lower fuel and energy consumption.
