* Gradation Numbers 24, 25, 3, 4A, and 4 are main line ballast materials * Gradation Numbers 5 and 57 are yard ballast materials. Fine Aggregates. Enter the individual weights retained in grams for each individual sieve and the pan.
Most specifications require coarse and fine aggregate to conform to the requirements, including the gradation, of ASTM C33. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.. ASTM Standards.
the individual percent retained plot, 2) the Coarseness Factor Chart, and 3) the 0.45 power gradation plot.
1.
The use of aggregates that would not necessarily meet ASTM C 33 specifications was put forth as a possibility. By inputting sieve size analysis (gradation) information for up to three coarse aggregates and two fine aggregates, and the relative percent of each aggregate to be used in the mixture, this web applet allows you to view plots of the percent passing, percent retained, workability chart, ASTM C33 curve, and 0.45 power curve for the combined aggregate gradation.
The individual % of grams retained, cumulative % retained & cumulative % passing will be calculated. Concrete producers then use that material to make concrete, the properties of which are quite dependent on the aggregate gradation, both coarse and fine. Where other materials are to be used, appropriate limits suitable to their use must be specified. Gradation Requirements Fine Aggregates Coarse Aggregates B Borrow and Structure Backfill Riprap Aggregate Base Subbase Aggregate Pavements or Shoulders ... T 304 Uncompacted Void Content of Fine Aggregate ASTM Test Methods D 4791 Flat Particles, Elongated Particles, or Flat and Elongated The use of aggregate fractions that would supply the missing intermediate (3/8 in. Coarse Aggregate Types Type Characteristics = Stone can consist of up to 10% of this size * Each Stone gradation can contain up to 10% upper and lower grades and some fine material (sand). Old Pa # = The old Pennsylvania Department of Transportation reference to aggregate sizing. Rip Rap

Perform the coarse aggregate gradation/sieve analysis according to ASTM C136. 200) Sieve in Mineral Aggregates by Washing. Leila Gharani Recommended for you C637 Specification for Aggregates for Radiation … Road Aggregate 101: Gradation or distribution of different sized stones Open graded aggregate vs. well graded aggregate. 26–6 (210-vi–NEH, October 1994) Chapter 26 Gradation Design of Sand and Gravel Filters Part 633 National Engineering Handbook Table 26–13 Data for designed filter band 26–29 Table 26–14 Design filter band data for example 26–6 soil 26–34 Table 26B–1 Selected standard aggregate gradations 26–41 Figures Figure 26–1 Grain size distribution curve for fine clay base soil 26–9 Road Aggregate 101: Nominal maximum and/or minimum sized stone in mix The nominal size distribution of an aggregate specification is defined as the range of sieve openings through which 100% of the aggregate can pass. 8 sieve) (9.5 to 2.36 mm). 2. There are also a few blended or graded aggregate sizes that combine the gradation of several aggregates. Aggregate size #8 is nominal size 3/8 to 0.094 inch (No. The charts below show typical gradations of various products based on required specifications from agencies and organizations such as state DOTs, AASHTO, etc. Anti-Skid . Coarse Aggregates. = Stone can consist of up to 10% of this size * Each Stone gradation can contain up to 10% upper and lower grades and some fine material (sand). 2. The particle size distribution, or gradation, of an aggregate is one of the most influential aggregate characteristics in determining how it will perform as a pavement material. 3. (X) = Stone consists largely of this size (..) = Stone can consist of up to 15% of this size (.) For coarse aggregate sources, see QPL 2.
C125 Terminology Relating to Concrete and Concrete Aggregates.
For example, #1 aggregate is nominal size 3½ to l½ inches (90 to 37.5 mm). How to create a dynamic map chart with drop-down (works with ANY Excel version) - Duration: 17:34. Gradation Types (see Graph) Aggregate gradation can be generally described by a few broadly defined gradation categories; each one describing a general type of gradation.
