Key Features

HINCOL CRMB is based on unique technology that enables homogeneity, stability and consistent properties of binder throughout the supply chain. To achieve this, special stabilising additives are used and a special manufacturing process is adopted and the result is a high performance bituminous binder with unique properties that are consistent. HINCOL CRMB 60 is ideally suited for hot climates. It enhances the key properties of asphalt mixes, i.e. deformation resistance and fatigue life. These improvements are the result of three vital physical changes which the polymer makes in the conventional binder structure: reduced temperature susceptibility, increased stiffness modulus and enhanced elasticity.
