specifications for aggregates are detailed in Section 904 and other sections for the various types of construction. These specifications are to be followed when inspecting aggregates. There are two general types of requirements for aggregate: quality and gradation. _____

Total Percent Passing the #200 Sieve by Washing Dry Sieving IM 306 Step instructions to determine percent passing the #200 sieve. • Restrictions on washing the entire sieve analysis sample or a separate smaller sample.
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. In HMA, gradation helps determine almost every important property including stiffness, stability, durability, permeability, workability, fatigue resistance, frictional resistance and moisture susceptibility (Roberts et ...
Jun 02, 2012· This experiment is carried out to find and check the gradation of the fine aggregate sand. The concrete consists of three basic solid materials, one is the sand whose fineness is checked by experiment no 1, the other two materials are the coarse aggregate that is the crush while the third is the fine aggregate that is the sand.

A sieve analysis (or gradation test) is a practice or procedure used (commonly used in civil engineering) to assess the particle size distribution (also called gradation) of a granular material by allowing the material to pass through a series of sieves of progressively smaller mesh size and weighing the amount of material that is stopped by each sieve as a fraction of the whole mass.

SIEVE ANALYSIS AND FINENESS MODULUS Sampling Since the reason for sampling aggregates is to determine the gradation (particle size) of the aggregate, it is necessary that they be sampled correctly. The results of testing will re" ect the condition and characteristics of the aggregate from which the sample is obtained.
aggregate testing for state or federally funded projects require Michigan Certified Aggregate Technician (MCAT) training at the level appropriate for the acceptance work. A few examples and the MCAT level required are listed below: Granular fill (Level 1) Subbase (Level 1) Base (Level 1) Concrete aggregates .
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.
Nov 09, 2014· The most important test is the sieve analysis of aggregate, whether it is 20mm, 10mm, 5mm and 1mm sizes. The crucial thing is I have to do it every delivery of aggregate and as per the frequency of sieve analysis, which is written in this article frequency of tests.

When determining an amount of material finer than a No. 200 (75μm) sieve by washing, the following Automatic Aggregate Washer accessories are recommended: 8in (203mm) and 12in (305mm) wetwash sieves (Select from table below), 8in (203mm) and 12in (305mm) brass sieve pans with drains. 3/8in Vinyl tubing and hose clamps can be used to connect ...
Aggregates Aalto. Gradation of aggregates Gradation describes the particle size distribution of the aggregate. The particle size distribution is an important attribute of the aggregate s. Large aggregates are economically advantageous in Portland cement and asphalt concrete, as they have less surface areaand, therefore, require less binder.
Nominal coarse aggregate sizes for the particular tab selected will show up under the individual titles. All white cells are input cells start by typing your name if is desired. Perform the coarse aggregate gradation/sieve analysis according to ASTM C136. Enter the original mass of the sample.
Sep 10, 2015· Washing and classifying of aggregate can be considered in two parts, depending on the size range of material. Coarse material: Generally above 3/8 in. (sometimes split at 1/4 in. or #4 mesh). In the washing process it usually is desired to remove foreign, objectionable material, including fine particles. Fine aggregate: From 3/8 in. and smaller.
Jun 25, 2014· The most efficient way to achieve workable of concrete is by adopting a good gradation of aggregate. Also aggregate comprises 85% of the volume of concrete. So we can definitely say that, most of the requirement of concrete in its plastic state is affected by aggregate properties and, "gradation of aggregate" is one of them.
Next, complete a gradation on the two fine aggregate sources and the bag house fines. Calculating the percent retained and percent passing on these materials follows the procedure just shown for the No. 8 aggregate. The wash gradation on the Aggregate is as follows: Dry weight of the original sample (before washing): g
