Sand Equivalent - Pavement Interactive

The sand equivalent test is meant to be a rapid field test. Specific issues with the sand equivalent test are: The sand equivalent test is not a direct measure of a HMA physical property. Rather, it is a measure of plastic fines and dust in the aggregate. These items may contribute to a reduced asphalt binder-aggregate bond. Therefore, if a ...
