Achieving appropriate in-place density is critical to the long-term performance of an asphalt pavement as a small change in inplace density can significantly affect the pavement service life. Thus, a Federal Highway Administration (FHWA) demonstration project was created for “Enhanced Durability of Asphalt Pavements through Increased In-place Pavem
