Results show that a simple quadratic fit between tp and θv can be given leading to a maximum error in the estimate of 0.55%. It is also shown that the dielectric model underlying each of the basecourses is different enough to warrant the use of a unique quadratic function (i.e. different quadratic coefficients) for each.pp.609-613en© The authors.componentTDRroadbasecoursedielectricmoisture contentConference Contribution - published2156-8073
