FHWA’s Increased In-Place Density Initiative

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.

Enhanced Durability of Asphalt Pavements through Increased In-Place Pavement Density

      Durability Workshop Only (2017)  
      Durability Workshop and Demonstration Projects (2016)  

Last updated August 2018

Topics Include:

  • The Importance of Density
  • Influencers on Durability
  • Construction Best Practices
  • Newer Technologies:
    • Intelligent Compaction
    • Pave IR
    • Warm Mix Asphalt
  • Tack Coat Best Practices
  • Longitudinal Joint Best Practices

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.
