Coarse aggregate angularity is important to ensure adequate aggregate interlock and prevent excessive HMA deformation under load (rutting). The mass (or count) of coarse aggregate particles meeting the fractured face specification is compared to the total coarse aggregate sample mass (or particle count) and converted to a percentage. If Percentage of particles (by mass or count) that meet the specified fractured face criteria. 4 (4.75 mm) sieve. Licensee agrees to submit to jurisdiction and venue in the state This is an indirect method for estimating fine aggregate angularity and texture. Prepare the aggregate sample by air-drying it so that there is clean separation of particles. Domestic orders are delivered via United Parcel Service (UPS) or United States Postal Service (USPS). The higher the void content, the higher the assumed angularity and rougher the surface. Concrete and Aggregate Testing: An ASTM How-to Guide . The test measures the voids in a sample results from the flowing of the aggregate into a standard container from a -standard height. Conshohocken, PA 19428-2959 USA. also agree to waive any claim of immunity you may possess. The coarse aggregate angularity (CAA) test is a method of determining the angularity of coarse aggregate (Figure 1). The system employs methods based on sound scien- tific concepts for the analysis of shape, angularity, and texture and provides the distribution of each of the characteristics in an aggregate sample. Sieve Analysis Test Report (T27, T11, T255) T304. The National Aggregates Association (NAA) developed the original test upon which the FAA test is based. Superpave specifies Method A to determine FAA. This value is often referred to as Fine Aggregate Angularity. 4 (4.75 mm) sieve (Figure 7) is chosen although others may be specified. The aggregate is then struck off and its mass is calculated by weighing. 200) in Mineral Aggregates by Washing the theory of liability, arising out of or related to the use or downloading of the ASTM Reproduction of any portion of an AASHTO test method in any format is strictly prohibited without written permission from AASHTO. 2The Aggregate Imaging System (AIMS) was recommended for measuring the characteris- tics of both coarse and fine aggregates.

ASTM International grants to the Subscriber and Authorized Governing Law, Venue, Jurisdiction. The number of fractured faces is usually specified as one or two per aggregate particle. The Fine Aggregate Angularity test (FAA),. The test sample should be large enough that the largest particle is no more than 1 percent of the test sample mass or the minimum test sample size should be as indicated in Table 1, whichever is smaller. This test is used to help ensure that the resulting HMA mixture will be resistant to deformation under repeated loads. Thoroughly mix the sample and reduce the sample to the required size in accordance with AASHTO T 248 (Reducing Field samples of Aggregates to Test Size). These efforts have proved quite successful, however reliable standard laboratory tests are still under development. journal article, please contact ASTM Customer Service, 100 Barr Harbor Dr., PO Box C700, West With method C, the measured void content depends not only on particle shape and texture, but gradation as well. Limited License. Base on the weight of the aggregate in the cylinder and a known aggregate specific gravity, the volume of voids as a percentage of total volume can be calculated. The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. When viewing a particle, hold it so that its face is viewed directly. Methods A and B are generally specified when trying to compare the angularity of different fine aggregate sources to remove the effect of gradation. The HMA-11A Spatula is purchased separately and meets specification requirements to strike off excess material. Sieve Analysis of Fine and Coarse Aggregates, and AASHTO T 11 . Method-1: Solids Point of view 1) Add measured quantity of water in the compacted aggregate until all the voids are filled and water appears to the surface. Transit Table 2: Superpave Mix Design Coarse Aggregate Angularity Specification, Table 3: Superpave Mix Design Coarse Aggregate Angularity Specifications by Design ESALs. FINE AGGREGATE ANGULARITY This property ensures a high degree of fine aggregate internal friction and rutting resistance. The following description is a brief summary of the FAA test, method A. P = percentage of particles with the specified number of fractured faces, F = mass or count of particles with at least the specified number of fractured faces, N = mass or count of particles not having the specified number of fractured faces. or non-infringement are disclaimed, except to the extent that these disclaimers are held to be This method uses a standard fine aggregate grading that is obtained by combining individual Proportional calipers determine percentages of flat and elongated particles in coarse aggregate samples. Recombine the individual sizes in the appropriate quantities to meet the specified standard gradation. Higher void contents correspond to higher fractured faces. you have Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. NCHRP Report 555. Masad, E.; Al-Rousan, T.; Button, J.; Little, D. and Tutmuluer, E. (2007). Spread the test sample on a clean flat surface for careful inspection and evaluation. The sample size for this procedure is approximately 1000g of material passing the No. An uncompacted void content (fine aggregate angularity) test is performed on a sample of fine aggregate with a bulk specific gravity of 2.647. The proposed imaging techniques are used to capture the aggregate angularity of 23 sand samples that represent a wide range of materials. For example, an employee of the Subscriber may be considered to be an Fine Aggregate Angularity (AASHTO T 304, Method A) 1 to 2. Gilson offers two models for this popular test. unauthorized use(s) of your password, or any known or suspected breach of security, including sub-licensed. It takes a sample of coarse aggregate and drops it into a cylinder of measured volume (Figure 4 and Video 1). Angularity of the fine aggregates was measured using Superpave fine aggregate angularity (FAA), direct shear test, compacted aggregate resistance (CAR), and VDG-40 videograder. Angularity is a representation of the looseness, surface defects or sharp angles of fine aggregates. If particle mass rather than particle count is to be used, sample preparation will take at least 12 hours or overnight because the aggregate needs to be oven dry after the washing procedure used to remove fine material. The material retained on the sieve is then used as the test sample. - Fine aggregate angularity (FAA) is determined using Method "A" (AASHTO T304) on each individual component with more than 10% passing #8 sieve (2.36mm) and on the current JMF blend. Brush adhering grains away from the lip and. FINE AGGREGATE ANGULARITY Both owner agencies and the paving and aggregate industries have questioned the validi-ty of the Superpave FAA requirement. October 2022 . This method uses each of three fine aggregate size factions. Therefore, test results not only account for form, angularity and texture, but they also account for fine aggregate gradation. It is a punch shear test that indirectly measures the shape and angularity of fine aggregates. data or for special, indirect, consequential or punitive damages, however caused regardless of ASTM will engage an independent consultant, subject to a confidentiality agreement, to review Conceptually, the CAR test which is similar to the California Bearing Ratio test is in the developing process of replacing the current Superpave standard for . Determine the bulk specific gravity of the fine aggregate. Site, online access to ASTM's journal for which the Subscriber maintains a current The FAA test is based on the assumption that more frac-tured faces will result in higher void content in the loosely compacted sample; however, this assumption is not always true. Void Content Apparatus / Fine Aggregate Angularity $ 110.00 Item #: VC-9102 Qty USA and Canada Prices Only. Friction angle derived from direct shear tests and slenderness ratio from the image analysis showed good correlations with rut depth. As with the FAA test, this loose uncompacted void content is indicative of the relative angularity and surface texture of the sample. The Federal Highway Administration (FHWA) Office of Technology Applications recommended Pennsylvania Department of Transportation Test Method 621 as a way to measure this quality. This video demonstrates Method A of the uncompacted void content of fine aggregate test, which is commonly referred to as the Fine Aggregate Angularity Test, or FFA Test. Download scientific diagram | Fine Aggregate Angularity test set-up with AG spent garnet. Fine aggregates from different regions of USA were collected along with their performance history. SHRP-LTPP database was also used to find any correlation between FAA and field rutting. Neither the electronic file nor the single hard copy print may be reproduced in any way. The higher values are specified for layers near the surface and for higher traffic levels. LoginAsk is here to help you access Fine And Coarse Aggregates quickly and handle each specific case you encounter. The CAA test estimates coarse aggregate angularity by visually inspecting a small sample of coarse aggregate and separating the sample into those pieces with a fractured face and those without (Figure 2).
