Abstract: Tests of the asphalt content in Asphalt Mixture have a lot of methods at present, centrifugal separation extraction method and combustion method is common. The author studied the effects of two test methods for asphalt content, and given the impact of the two test methods, the proposed test methods test methods and suitable for different conditions.
Keywords:centrifugal extraction method; combustion; asphalt content; coefficient of variation
