62 The use of RAM, including RAP and RAS, has increased in highway construction due to potential engineering, economic, and environmental benefits. Although the use of RAM in new asphalt mixtures can reduce the amount of virgin and nonrenewable materials required and increase the rutting resistance of pavements, it may also compromise cracking resistance.
