  • 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. The requirement is also dependent upon the type of HMA layer (e.g., base course or surface course). Issues with the Sand Equivalent Test. The sand equivalent test is meant to be a rapid field test. Specific issues with the sand equivalent test are:

  • Sand equivalent test Wikipedia

    The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand equivalent value indicates that there is less clay‐like material in a sample. During the test
