Crumb Rubber Modified Bitumen (CRMB)
CRFlex®55/60 is a range of Crumb Rubber Modified Bitumen (CRMB). It is manufactured with crumb rubber produced by recycling used tyres with bitumen and some specific additives to improve the durability of the pavements. It is specially formulated with unique technology that enables homogeneity, stability and consistent properties of the binder. To achieve this, special stabilizing additives are used under special manufacturing process resulting in unique properties that are consistent and as per the latest technical guidelines.
Benefits
- Higher resistance to deformation at elevated pavement temperatures.
- Better adhesion between aggregate and binder.
- Higher fatigue life and delayed cracking and reflective cracking.
- Overall improved performance in extreme climatic conditions and under heavy traffic conditions.
- Better water resistance.
- Resistance to creep and higher indirect tensile strength.
- Lower susceptibility to daily and seasonal temperature variations.
