dried the samples are cooled to room temperature, then reduced to testing size in accordance with AASHTO T 248. After reducing the aggregate to the proper testing size the first test performed in this example will be a washed gradation. Washing the sample will be done in accordance with AASHTO T
AASHTO T 27 - Standard Method of Test for Sieve Analysis of Fine and Coarse Aggregates Published by AASHTO on January 1, 2014 This method covers the determination of the particle size distribution of fine and coarse aggregates by sieving.
4.1 Some contract documents specify certain aggregate sizes for specific uses or may suggest one or more of these sizes as appropriate for the preparation of various end-product mixtures. In some cases, closer limits on variability of the aggregate grading are required.
proportions of various particle sizes in a mineral aggregate. In ia, however, the WASHED SIEVE ANALYSIS is used, and will be discussed in this section. Standard procedures for running the sieve analysis are given in AASHTO T 27 and AASHTO T 11. Regardless of the size of the aggregate, the procedure for running a sieve analysis

AASHTO #1's are too bulky to be used as a surfacing material, however, it makes an excellent stone for subgrade stabilization. Applications for this stone include construction entrances and ditch lining. It will not compact, and is a clean material.
Classification of Aggregates Based on Size. Aggregates are available in nature in different sizes. The size of aggregate used may be related to the mix proportions, type of work etc. the size distribution of aggregates is called grading of aggregates.
Find the most up-to-date version of AASHTO M 43 at Engineering360. scope: This specification defines aggregate size designations and ranges in mechanical analyses for standard sizes of coarse aggregate and screenings for use in the construction and maintenance of various types of highways and bridges.
AND COARSE AGGREGATES AASHTO T 27 SCOPE The sieve analysis, commonly known as the gradation test, is a basic essential test for all aggregate technicians. The sieve analysis determines the gradation (the distribution of aggregate particles, by size, within a given sample) in order to determine compliance with design,
Where standard sizes of coarse aggregate designated by two or three digit numbers are specified, the specified gradation may be obtained by combining the appropriate single digit standard size aggregates by a suitable proportioning device which has a separate compartment for each coarse aggregate .

AASHTO #3. 3A • This material is similar to AASHTO #1, but has a 2.5 inch top size. • It is also a bulky material but is ...
All aggregates are porous, but some are more porous than others. How porous an aggregate is determines how much liquid may be absorbed when soaked in water. AASHTO T 85 defines absorption as the increase in the weight of aggregate because of water in the pores of the material, but not including water adhering to the outside surface of the ...
