METHOD OF TEST FOR SAND EQUIVALENT dot.ca.gov

During the initial testing, 33 laboratories failed the sand equivalent proficiency test. Consequently, retests for these 33 laboratories were required to ensure that laboratories are correctly following the test methods and using the correct equipment. The retest samples provided laboratories corrective measures to obtain acceptable results.

APPENDIX C TESTS AND PROCEDURES

SAND EQUIVALENT TEST The sand equivalent test, described in AASHTO T 176, is a method of determining the relative proportion of detrimental fine dust or clay-like materials in the portion of aggregate passing the 4.75 mm (No. 4) sieve. The sand equivalent test is conducted as follows 1.
