The Federal Highway Administration (FHWA) and Asphalt Institute presented an Enhanced Durability through Increased In-Place Pavement Density Workshop to ten states as shown below. This one-day workshop offered owners and contractors the opportunity to learn about the dramatic durability increases that can be realized from relatively small increases in in-place densities. This workshop provided the most current information on how to achieve consistently high densities and the resulting economic benefits.

Research has conservatively indicated that a 1% increase in density at the time of construction can result in a 10% increase in service life. Using these values, life cycle cost analysis indicates that an 8.8% savings can be expected.
