Most agencies have developed a means of accommodating the stiffness of the reclaimed asphalt from the RAP by the selection of the particular grade of the virgin binder. The Asphalt Institute strongly endorses the use of RAP in asphalt mixtures. Whenever possible, variances of more than 25 degrees from the mix temperature should be avoided. Care should be taken to ensure that surface friction is not compromised, especially if the pavement is used for vehicular traffic.
