2019-5-10convenience. Figure 1 shows principal construction uses of aggregate road materials by sizes. Figure 2 is a tabulation of gradings for coarse and fine aggregate sizes. These charts were prepared from the 1960 Standard Specifications of the State Highway Department of Indiana in order to provide a quick reference.
AASHTO No. 57 AASHTO 57 crushed stone is a clean material that wont compact and features a 1 12-inch top size. Typical applications include as backfill for retaining walls, as well as a sub-base for sheds and driveway gravel or stone. Many ready-mix concrete and hot-mix asphalt products contain No. 57 aggregate as its primary ingredient.
Sieve Analysis ASTM C 136, AASHTO T-27 This test method evaluates the gradation of aggregate using a series of sieves. The results are then plotted on to a semi-log aggregate gradation chart. This chart shows the particle size distribution for any given aggregate and can then be better evaluated for its use in portland cement concrete

Aggregate Sizing Explained. ... All-in aggregate, similar to that of its name, is aggregate containing a proportion of material of all sizes from a pit, crushing plant or river bed. Also known as Ballast, this type of material is generally used to repair small cracks and pavement foundations.
The terms and nomenclature used in the Aggregate Producers database are as follows Abs - Absorption in percent. Carb - Percent of gravel that is derived from carbonate rock sources.. ASR - Alkalai Silica Reactivity value as determined by AASHTO T 303.. baghse fines - Mineral filler collected in the baghouse of a particular asphalt plant, permitted for use after approval testing and when ...
2009-1-28participant, we suggested five or six aggregate proportions. At each location, the intermediate coarse aggregate was obtained from the same quarry as the larger coarse aggregate to keep the particle shape consistent and thereby minimize the influences of different particle shapes on test results. 20 25 30 35 40 45 100 80 60 40 20 0 Coars enes s ...

ASTM No. 57 is a type of aggregate grading. The ASTM specification for this type of concrete aggregate is C 33. Stone mixes made using this type of aggregate are porous. According to Materials for Sustainable Sites by Meg Calkins, larger sizes such as 57, 67 and 78 will have more rapid permeability and little susceptibility to clogging.
