The BIOMAK SA produces varius types of modified bitumen.
The modified bitumen produced is high quality using an elastomeric material.
The modified bitumen which we produce are improved compared the common bitumen to :
- Increased resistance to permanent deformation due to the increased viscosity and elasticity.
- Resistance to cracking and raveling because of the increase in bitumen flexibility, which allows the asphalt to absorb mechanical and thermal stresses.
- Better adhesion bitumen and aggregate resulting from an increased affinity of the modified bitumen towards the aggregate.
- Improved performance at lower temperatures because of the increased flexibility over a wide range of temperatures.
All the above has the effect of creating a safer and better road where the frequency of maintenance is reduced and increases the lifetime of the pavement.
