Abstract
A non-tacky asphalt packet in which the surface is coated with a continuous layer of polymer compatible with the asphalt, and which has a surface-to-volume ratio which in the presence of heat makes the asphalt melt in an adequately short time such that when n dispersed in an aggregate mixture allows the asphalt to melt and coat the aggregate uniformly as the aggregate reaches the maximum mix temperature, and prior to degradation of the asphalt due to excessive temperature.
