Influence of conductive additive on temperature susceptibility of asphalt binders
The effects of graphite on temperature susceptibility of asphalt binders were investigated by penetration test, Ring & Ball softening point test and viscosity test. And penetration index (Ip), viscosity-temperature susceptibility (SVT), and penetration-viscosity numbers (NPV) were introduced to evaluate the effects. The results show that the penetration, softening point and viscosity of asphalt binder increase with the increase of content of graphite. This means that the addition of graphite makes asphalts stiffer. The results from Ip, Npv and SVT show that temperature susceptibility is reduced by the addition of graphite.
