AASHTO defines overloading large sieves as weight retained in excess of times the sieve opening in in. (mm), as expressed in gm/in. 2 (kg/m 2). For fine aggregate, no weight shall be in excess of 4 gm/in. 2 (7 kg/m 2). 3. Coarse Aggregates After the material has been sieved, remove each tray, weigh each size
The AASHTO system ranks specs according to size (110), with 1 being the largest (all material must pass a 4 sieve) and 10 being the smallest (all material passing a 3/8 sieve). Multidigit specs represent a blend of one or more of the ten basic specs ( AASHTO 57 is a blend of AASHTO 5 and AASHTO 7).
#0183;#32;The maximum size aggregate used may be dependent upon some conditions. In general, 40mm size aggregate used for normal strengths and 20mm size is used for high strength concrete. the size range of various coarse aggregates given below. Coarse aggregate: Size: Fine gravel. 4mm 8mm. Medium gravel. 8mm 16mm. Coarse gravel.
Coarse aggregate grading shall conform to appropriate size designation of AASHTO M 43 when tested in accordance with AASHTO T 27. Grading and material finer than No. 200 (75 #181;m) sieve te sting shall be part of the Quality Control Plan required in Subsection Fine Aggregate
Road Aggregate 101: Important Stuff, Coarse Aggregate The AASHTO system ranks specs according to size (110), with 1 being the largest (all material must pass a 4 sieve) and 10, The nominal size distribution of an aggregate specification is defined as.
Maximum size is one size larger than nominal maximum size. Note 1: Based upon the tests required, the sample size may be four times that shown in Table 2 of the FOP for AASHTO T 27/T 11, if that mass is more appropriate. As a general rule the field sample size should be such that, when split twice will provide a testing sample of proper size.

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. Published by AASHTO on January 1, 2020. This method
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.
AASHTO #8 is a large grade of crushed stone. Like AASHTO #1, #3, and #57, it is a clean material that will not compact. However, the top size of AASHTO #8 aggregate is significantly smaller, making it ideal for different applications within the construction industry.
