Low-temperature bitumens are special bituminous binders that allow lower handling temperatures (manufacturing and installation) than conventional bitumens with similar penetration. This reduction in temperature offers a series of advantages, namely:
- Increase durability of the mixture due to the reduction in manufacturing temperature. This contributes to less product aging
- Reduction in atmospheric emissions and, therefore, environmental improvement
- Reduction in consumption of electricity on lowering manufacturing temperature by approximately 30°C. This implies cost savings at the bituminous mixture manufacturing plant
- Improves working conditions for operators during manufacturing and installation
These low-temperature bitumens are applied to all types of mixtures and in the same manner as normal bitumen, from the manufacturing of conventional asphaltic mixtures to anti-crack mixtures and discontinuous mixtures using PMB 45/80-60 BT and PMB 45/80-65 BT bitumens.
