AASHTO T 111-21 PDF Download

The AASHTO T 111-21 standard provides guidelines for determining the mineral matter content in various asphalt materials. The scope of this test method covers both bulk and recovered asphalt binders, as well as distillation residues of emulsified, cut-back, and other synthetic or naturally occurring asphaltic materials.

The purpose of this standard is to quantify the mineral matter or ash content present in these asphalt materials, which can have implications for the overall performance and quality of the asphalt. The determination of mineral matter is important because it can affect the properties and characteristics of the asphalt, such as its viscosity, aging, and durability.
