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.5 pagesen© 2018, Exeley Inc.TDRroadbasecoursedielectricmoisture contentJournal Article10.21307/IJSSIS-2019-076ANZSRC::0906 Electrical and Electronic EngineeringANZSRC::090603 Industrial ElectronicsANZSRC::090502 Construction EngineeringANZSRC::090507 Transport Engineering1178-5608ANZSRC::4009 Electronics, sensors and digital hardwarehttps://creativecommons.org/licenses/by-nc-nd/4.0/Attribution-NonCommercial-NoDerivatives
