If crushed ACBFS is selected for the concrete coarse aggregate, use No. 57 or 67 size. Where gravel or limestone is selected and the total combined quantity of the listed items is greater than 10,000 square yards (8000 m 2), provide coarse aggregate in No. 57 or 67 size.
Dec 15, 2003· I believe the Pennsylvania Department of Transportation''s Standard Highway Specifications, Publication 408, are available on line. AASHTO 57 stone was listed in the section on coarse aggregates. The gradations are also given for AASHTO No. 1, 3, 5, 67, 7, 8, and 10 coarse aggregate.
Aug 04, 2015· Aggregates used in this study were collected from three different quarries. For each aggregate type, upper and lower limits of three different gradations, modified AASHTO #57, Okloma Aggregate Association (OKAA) Type M, and Okloma DOT (ODOT) Type A, were selected.
Gradation of stone and rock is found by ASTM C136, the Test Method for Sieve Analysis of Fine and Coarse Aggregates. Gage numbers are used to identify aggregate. ASTM No. 57 aggregate is found using a sieve, through which all of the stones will pass. No ASTM 57 aggregate stone is smaller than a No. 8 seize with a sieve.
Jul 15, 2016· Include the following when subbbase or base aggregate is required. Delete the text in paragraph (b) and substitute the following: (b) Subbase or base aggregate. In addition to paragraph (a) above, conform to the following: (1) GradationTable 7032 (2) Liquid Limit, AASHTO T 8925 max. (3) SEP (SE/P200 (SE/P75 Index) min.
10/11/2012 7 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 of the aggregate can pass. Road Aggregate 101: Gradation or .
AASHTO #57 Stone Specs AASHTO #57 stone as defined by quarries, state agencies, etc. is an opengraded, selfcompacting aggregate blend of size 5, 6, 7 stone. This material cannot be ''compacted'' in a true sense, but can be properly oriented with compaction equipment. This is particularly important when using #57 stone under FlexiPave surfaces.
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 endproduct mixtures. In some cases, closer limits on variability of the aggregate grading are required. 5. Manufacture The standard sizes of aggregate described in this clas
C. Aggregates for Optimized Gradation. 1. Coarse Aggregate Requirements. a. Coarse aggregate includes all aggregate particles greater than or retained on the ½inch sieve. b. The physical requirements for coarse aggregate are as specified in Table 9022 for Class 6AAA and the following: i. Maximum 24 hour soak absorption of percent; ii.
Aggregate specifications have an allowable range of different stone sizes, expressed as a percentage of the total weight of sample. This. gradation specification. is reported on a table or chart (see example above). The. nominal. maximum size of an aggregate specification is defined as the smallest sieve opening through which of the ...
* Gradation Numbers 24, 25, 3, 4A, and 4 are main line ballast materials * Gradation Numbers 5 and 57 are yard ballast materials. 2. Old Pa # = The old Pennsylvania Department of Transportation reference to aggregate sizing. 3.
Granular wellgraded soil/aggregate mixtures, 35% fines. Most pavement subbase materials can be used in lieu of this layer. Most pavement subbase materials can be used in lieu of this layer. 3, 357, 4, 467, 5, 56, 57, 6, 67, 68, 7, 78, 8, 89, 9, 10
standard ASTM C 33 (AASHTO M 6/M 80) sieves for fine aggregate have openings ranging from 150 µm to mm (No. 100 sieve to . 3 ⁄ 8. in.). The 13 standard sieves for coarse aggregate have openings ranging from mm to 100 mm ( in. to 4 in.). Tolerances for the dimensions of openings in sieves are listed in ASTM E 11 (AASHTO M 92).
Gradation Charts. The charts below show typical gradations of various products based on required specifications from agencies and organizations such as state DOTs, AASHTO, etc. AntiSkid . Coarse Aggregates. Fine Aggregates. MicroSurfacing. Rip Rap
In Phase 2, the number of gradations was narrowed down to three, namely MAASHTO #57, OKAA Type M and ODOT Type A. These three gradations were tested with all three aggregate sources, as mentioned earlier. To simulate an opengraded base course, MAASHTO #57 and OKAA Type M specimens were compacted with standard Proctor effort, whereas, modified
