The Research and Application of Methylene Blue Testing Method to Characterization of Powder Lot (or Fine Aggregate) in Asphalt Mixture

Abstract:

There is a comparison among the six Methylene Blue testing methods from different areas and institutes which respectively belong to China, U.S. and Britain. So as to improve the current MBV test of powdery lot used in asphalt mixture in China，it is found that current MBV test needs to be improved by analyzing powder lot Suspension、the concentration of Methylene Blue solution、stirring speed、powder lot types, temperature and soil content. So the revising suggestion to test method T0349-2005 included in standard JTG E42- 2005 is put forward. Later in the micro-surfacing test it is found that by adjusting the silt content, the water damage resistance and anti-abrasion abilities have been affected significantly which are good related to the MBV test recommended in this paper, so it is evident that the improved MBV test is crucial to the quality control over fine aggregates.
