Abstract
An asphalt release agent for preventing hot road asphalt, especially polymer-modified asphalt, from sticking to surfaces of delivery truck beds is provided. The release agent includes a water-based mixture of polycycloaliphatic amines and polyalkylene glycols. The release agent is applied onto the truck beds to create a slippery non-stick surface so that the road asphalt which comes in contact with such truck bed surfaces will not adhere.
