摘要

The method for detecting or quantifying an asphalt additive comprises adding a homogeneous mixture of the additive and a tracer to the asphalt and detecting or quantifying the tracer. An Independent claim is also included for a process for homogeneously dispersing a powdered additive in solid asphalt, comprising melting the asphalt, stirring the additive into the melt to form a homogeneous mixture, and solidifying the mixture by cooling.
