A novel Cold Rolled Asphalt mixtures for heavy trafficked surface course

The experimental results show a significant improvement in the mechanical properties and a substantial upgrading of material resistance to water sensitivity by the incorporation of BBF in the CRA. Moreover, the required strength i.e. 125 pen HRA stiffness modulus can be achieved after just several hours from de-moulding which represents a significant advantage when compared with the conventional reported curing times of 2-24 months for the traditional CBEMs.
