in the gradation of aggregates on the properties of asphalt concrete mixes. The gradation variation tested represented the extremes for a typical construction project. The specific objectives of the study were to determine the effect of gra dation variation on 1. Creep behavior as a
Aashto Aggregate Gradation Chart. Use from all supply sources.The gradation must be uniform from any one source and not change from the low to the high gradation limits.The fineness modulus of samples taken from proposed sources must be a minimum 2.50 and a maximum 3.10 when tested under aashto m 6.Fine aggregate.
The important characteristics of aggregates for concrete are listed in Table 5-2 and most are discussed in the following section Grading. Grading is the particle-size distribution of an aggregate as determined by a sieve analysis ASTM C 136 or AASHTO. 80. Design and Control of Concrete Mixtures EB001. Table 5-1. Rock and Mineral Constituents ...
Apr 11, 2020 The maximum size of coarse aggregate used in concrete has a bearing on economy. Usually more water and cement is required for small-size aggregates than for large sizes The water and cement required for a slump of approximately 3 in. and wc ratio 0.54 by wt. is shown in Fig. 4-6
Aggregate is another significant constituent of concrete which takes up to 60-90 of total concrete volume and its gradation has a huge impact on characteristics of concrete.

ASTM C136 AASHTO T 27 is the test method used for the sieve analysis of construction aggregates and specifies the mass of the sample to be tested based on the maximum particle size. This same standard also limits the maximum quantity of material retained on each sieve to enable adequate separation and avoid damage to the sieve mesh.
Have a coarse aggregate sample, fine aggregate sample, or mixture of both, dried and ready to be tested. Be able to demonstrate sample preparation, the sieve analysis of the prepared aggregate, and complete all calculations relating to the gradations. The assessor will check the sieving efficiency of all shakers. T37 D546

AASHTO table. Gradation - Gradation is the particle size distribution of aggregates determined by using sieves with square openings. The percentage of materials allowed to pass each sieve is usually referred to in the specification for the intended item. For instance, the specifications may call for an AASHTO No. 57. The gradation,

AASHTO 57 Stone Specs AASHTO 57 stone as defined by quarries, state agencies, etc. is an open-graded, self-compacting aggregate blend of size 5, 6, amp 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 Flexi-Pave surfaces.
Aggregates used for stone matrix asphalt mixtures are required to meet the requirements of AS aggregates in accordance with Section 904.03 a. These requirements include testing with the Micro-Deval abrasion apparatus AASHTO T 327 and determination of the aggregate degradation in accordance with ITM 220. Additional requirements for . . . in .
