This study investigates the electrical conductivity of graphite nano-platelet (GNP)-taconite modified asphalt binders and its application for damage sensing. The GNP-taconite modified asphalt binders are prepared using a high-velocity shear mixer. Different combinations of GNP and taconite are added to the binder, and the electrical conductivity is measured by a four-probe conductivity test. It is shown that the addition of GNP and taconite could effectively enhance the electrical conductivity of asphalt binders. Meanwhile, the results also demonstrate the influence of humidity on the conductivity measurement, which adds a new consideration of applying this material for damage sensing.
