This test method is used primarily to determine the grading of materials proposed for use as aggregates or being used as aggregates. The results are used to determine compliance of the particle size distribution with applicable specification requirements and to provide necessary data for control of the production of various aggregate products and mixtures containing aggregates. The data may also be useful in developing relationships concerning porosity and packing.
MTI laboratories are accredited by TAF (ISO/IEC 17025) to perform testing standard CNS 486 for Sieve Analysis of Fine and Coarse Aggregates.
