Accurate determination of the amount of material smaller than 75 µm (No. 200) cannot be made using just AASHTO T 27. If quantifying this material is required, use AASHTO T 11 in conjunction with AASHTO T 27. This FOP covers sieve analysis in accordance with AASHTO T 27-22 and materials finer than 75 µm (No. 200) in accordance with AASHTO T 11-22 performed in conjunction with AASHTO T 27. The procedure includes three methods: A, B, and C. Apparatus  Balance or scale: Capacity sufficient for the masses shown in Table 1, accurate to 0.1 percent of the sample mass or readable to 0.1 g, and meeting the requirements of AASHTO M 231  Sieves: Meeting the requirements of ASTM E11  Mechanical sieve shaker: Meeting the requirements of AASHTO T 27  Suitable drying equipment (refer to FOP for AASHTO T 255)  Containers and utensils: A pan or vessel of sufficient size to contain the sample covered with water and permit vigorous agitation without loss of material or water  Optional - Mechanical washing device - Mallet: With a rubber or rawhide head having a mass of 0.57 ±0.23 kg (1.25 ±0.5 lb) Sample Sieving  In all procedures, the sample is shaken in nested sieves. Sieves are selected to furnish information required by specification. Intermediate sieves are added for additional information or to avoid overloading sieves, or both.  The sieves are nested in order of increasing size from the bottom to the top, and the sample, or a portion of the sample, is placed on the top sieve.  The loaded sieves are shaken in a mechanical shaker for approximately 10 minutes, refer to Annex A, Time Evaluation. 40_T27_T11_short_22_errata Aggregate 12-1 Pub.
