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%, 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. The main objectives of this study are to improve the design of the prototype field permeameter; create a database of soil-water retention characteristics for a wide range of aggregate base materials that are needed for the theoretical calculation of saturated hydraulic conductivity; validate the permeameter measurements by comparing with the standard laboratory measurements; develop a standard procedure for performing the test, guidelines for calibration of the device, and a user manual; and demonstrate the feasibility of using the device as a rapid QC/QA tool for determining the in-situ permeability of pavement base course layers.
