PDF Rejuvenation vs. Re-Paving Drum Point - Total Asphalt

As asphalt ages, the petroleum elements of the binder oxidize and the asphalt loses its elastic properties and becomes brittle; whereupon the road surface cracks, allowing freeze-thaw cycles to destroy the road. Rejuvenation reverses the aging process by adding back the petroleum fractions needed for elasticity of the binder.
