NCHRP 20-07/Task 382 [Completed]

Longer Pavement Life from Increased In-Place Density of Asphalt Pavements
[ NCHRP 20-07 (Research for AASHTO Standing Committee on Highways) ]

  Project Data
Funds: $75,000
Research Agency: Dale S. Decker, LLC
Principal Investigator: Dale Decker
Effective Date: 10/5/2015
Completion Date: 3/31/2017

The objective of this research was to prepare a synthesis summarizing the current state of knowledge of in-place density of asphalt pavements as well as the current practices of agencies regarding how in-place density is measured and specified. 

The project final report is available here as NCHRP Research Report 856: Specifying and Measuring Asphalt Pavement Density to Ensure Pavement Performance. It was also provided to the AASHTO Subcommittee on Materials for review and possible action.
