AIM The fine aggregate angularity test determines the loose uncompacted void content of a fine aggregate material. APPARATUS Cylindrical Measure, Funnel (Pycnometer Top), Funnel Stand, Square Glass Plate, Pan, Metal Spatula, Balance PROCEDURE (MET
Pine AIMS visually evaluates aggregate properties Pine
The AIMS2 characterizes coarse aggregate angularity, sphericity, flatness, and elongation and provides a surface texture index. Fine aggregate consists of particles passing the 4.75 mm (No. 4) sieve and retained on the 0.075 mm (No. 200) sieve. The AIMS2 characterizes fine aggregate angularity and
WSDOT FOP for AASHTO T 3041 .When measured on any aggregate of a known grading, void content provides an indiion of that aggregate''s angularity, sphericity, and surface texture compared with other fine aggregates tested in the same grading.When void so as to prevent rocking of the apparatus during testing.
AIM The fine aggregate angularity test determines the loose uncompacted void content of a fine aggregate material. APPARATUS Cylindrical Measure, Funnel (Pycnometer Top), Funnel Stand, Square Glass Plate, Pan, Metal Spatula, Balance PROCEDURE (METHOD A) Obtain an aggregate sample by separating individual sizes from the No. 8 (2.36 mm) sieve to the No. 100 (150 mm) sieve.

Overview. The coarse aggregate angularity (CAA) test is a method of determining the angularity of coarse aggregate (Figure 1). Coarse aggregate angularity is important to ensure adequate aggregate interlock and prevent excessive HMA deformation under load ().. Figure 1: Angular Coarse Aggregate. The CAA test estimates coarse aggregate angularity by visually inspecting a small sample of coarse
• SG40 Fine Aggregate Angularity Apparatus • 100ml copper Cylindrical Measure Funnel • Funnel Stand • Glass Plate for calibration The apparatus accurately determines the uncompacted void content of fine aggregate samples. This procedure indies the angularity and sphericity of fine aggregate and its workability in a mixture.
Flakiness Index and Elongation Index Test on Coarse Aggregates
Mar 02, 2019 · The particle shape of aggregate is determined by the percentages of flaky and elongated particles contained in it. In case of gravel, it is determined by its Angularity Number. Flaky and Elongation is conducted on coarse aggregates to assess the shape of aggregates. Aggregates which are Flaky and elongated are detrimental to the higher workabilityContinue reading "Flakiness Index
Implementation of a Fine Aggregate Angularity Test
Implementation of a Fine Aggregate Angularity Test Tim Aschenbrener 1.0 Introduction Rutting of a hot mix asphalt (HMA) pavement is primarily related to aggregate structure and secondarily related to asphalt cement stiffness. One of the key components of the aggregate structure is the angularity of the fine aggregate.
Aggregate testing equipment is used for testing mechanical and physical properties, geometric, chemical and thermal properties of aggregates. Coarse Aggregate Angularity Apparatus Certified Material Testing . The Coarse Aggregate Angularity Apparatus utilizes a scaledup apparatus and procedure similar to that used for evaluation of fine aggregate.
The Fine Aggregate Angularity Apparatus determines the uncompacted void content of fine aggregates to determine angularity and sphericity properties that affect workability of mix designs. Gilson offers two models for this popular test.
The apparatus consisted of a small cone, tamping rod, volumetric flask, and an oven. Fine Aggregate Angularity may be found on the laboratory handouts on in appendix A in the report and in ASTM C125206, Method C. The volume of the cylindrical measure was determined prior to the lab test by the lab instructor. The mass of the empty
Evaluation of the Compacted Aggregate Resistance Test
The Compacted Aggregate Resistance (CAR) test is a procedure used to analyze the quality of asphalt. It is a punch shear test that indirectly measures the shape and angularity of fine aggregates. The CAR test is in the developing process of replacing the current Superpave standard for fine aggregate angularity.
The SG42 apparatus for uncompacted void content of coarse aggregate utilizes a scaledup apparatus and procedure similar to that used for evaluation of fine aggregate. Gradation and void content data provide an indiion of angularity, sphericity, and surface texture.
