AASHTO T 111-11 (2019) PDF Download

The AASHTO T 111-11 (2019) standard provides a method for determining the mineral matter content in solid, semisolid, or liquid bitumens. The purpose of this test is to assess the level of mineral impurities in asphalt materials, which can affect the overall performance and durability of asphalt pavements.

The test procedure outlined in the standard involves heating a sample of the asphalt material in a furnace to completely burn off the organic components, leaving behind the mineral matter or ash residue. The remaining ash is then weighed, and the percentage of mineral matter is calculated based on the weight of the original sample.

This standard is applicable to various types of bituminous materials, including asphalt cements, cutback asphalts, and emulsified asphalts. It is commonly used in quality control and quality assurance programs to ensure that the asphalt materials used in construction projects meet the required specifications and performance criteria.
