Rapid, Self-Contained in Situ Permeameter for Field QC/QA of Pavement Base/Subbase Materials

Recent studies have shown that the coefficient of variation of in situ permeability is as high as 50 to 400 percent, making base/subbase permeability the most variable engineering parameter in the pavement system. To really understand how this variability is affecting pavement performance, a rapid in situ test is needed that can be used to collect many data points over a small area. This research project addresses research tasks to develop an automated in situ permeability test that takes less than 30 seconds per test location, allowing for spatial analysis of the results. This is possible using an innovative gas-pressurized system. Spatial maps of the in situ permeability can be used as field QC/QA criteria for pavement base/subbase to identify field problems such as segregation and particle degradation.
