Sieve analysis determines the gradation or distribution of aggregate particle sizes within a given sample. Accurate determination of material smaller than 75 µm (No. 200) cannot be made with AASHTO T 27 alone. If quantifying this material is required, it is recommended that AASHTO T 27 be used in conjunction with AASHTO T 11.
