  • Sand Equivalent Pavement Interactive

    Minimum specified sand equivalent values for fine aggregate in HMA range from 26 to 60 with the most common being 45. Aggregates recovered using the ignition furnace appear to be unsuitable for sand equivalent testing because it appears the burning process creates more material that will show up on the sand
