This invention describes an apparatus and method for analyzing the rutting and stripping characteristics of hot mix asphalt concrete samples. The apparatus measures the vertical penetration of a wheel rolling in a reciprocating motion across the surface of a compacted asphalt mix specimen. It incorporates precise environmental control and includes features for testing two or more samples simultaneously under wet or dry conditions or a combination of wet and dry conditions.
