Abstract
A method for quality testing asphalt includes: directing light from a light source to at least one surface of asphalt; detecting light reflected or refracted from the at least one surface of the asphalt using a light detector; and assigning a number indicating the quality of the asphalt in response to detecting light reflected or refracted from the at least one surface of the asphalt.
