DIELECTRIC PROPERTIES OF ASPHALT PAVEMENT

dielectric properties of asphalt pavement This paper describes dielectric properties of asphalt pavement that were studied in the process of developing a roller mountable microwave asphalt pavement density sensor as part of the National Cooperative Highway Research Program IDEA project.Dielectric Constant, Strength, & Loss Tangent - RF Cafe,In general, low dielectric constants (i.e., Polypropylene) result in a "fast" substrate while large dielectric constants (i.e., Alumina) result in a "slow" substrate. The dielectric loss tangent is defined by the angle between the capacitor's impedance vector and the negative reactive axis,Dielectric Strength - CROW,Dielectric Strength of Polymers An important electrical property of insulators is their dielectric strength. If a voltage is applied to an insulator and steadily increased, a point will be eventually reached where the electrical properties break down.
