During crushing and screening, cubical-shaped aggregate particles are created, along with so-called flat or elongated shaped particles, and fines. Since the advent of Superpave mixes in the late 1990s, mix designs have limited the percentage of flat or elongated particles allowed in a mix.
Dec 06, 2016· In the case of crushed aggregate, the particle shape depends not only on the nature of the parent material but also on the type of crusher and its reduction ratio, i.e. the ratio of the size of

flat and elongated aggregate from crusher in arab Flakiness and Elongation of aggregates and Concrete,Dec 06 2016 · In the case of crushed aggregate the particle shape depends not only on the nature of the parent material but also on the type of crusher and
Flat and Elongated Particles of Aggregate Those particles having a ratio of length to thickness greater than a specified value. Length the maximum dimension. Thickness the maximum dimension perpendicular to the length and width. Width the maximum dimension in the plane perpendicular to the length. SCOPE This test method covers tests for flat particles, elongated particles, or flat and elongated particles in coarse aggregate.
Apr 28, 2017· This will always result in a low crusher throughput tonnage, the production of more flat and elongated product particles and oversized product. This typically prompts crusher operators to tighten the crusher setting in order to get the crusher to make the smaller product size that they are trying to produce.
Dec 06, 2016· In the case of crushed aggregate, the particle shape depends not only on the nature of the parent material but also on the type of crusher and its reduction ratio, i.e. the ratio of the size of
The percentage of flat and elongated particles has been related to volu- metric properties; therefore, changes in percentages of flat and elongated particles may be related to changes in volumetric properties. However, flat and elongated aggregate tests performed at the 5 1 ratio are generally insensitive to production changes in aggre- gate shape.
Aggregate shape characteristics play an important role in the performance of the aggregate materials. The type of crusher and rock may play an important role in aggregate shape characteristics. elongation ratio (E), flat and elongated ratio (FE), shape factor (SF), aspect ratio (AR), sphericity (Sp), Rittenhouse’s sphericity (RS

determined to be flat and elongated if the maximum (length) to minimum (thickness) dimension ratio is greater than five (3). This technique of measuring the shape of the particle is known simply as the flat and elongated measurement of an aggregate particle. The Superpave aggregate shape requirements specify that no more than 10 percent of the
How cubical do the aggregate particles used in Stone Matrix Asphalt (SMA) need to be to achieve acceptable performance? European specifications require SMA aggregates to have no more than 30 percent Los Angeles (L.A.) abrasion loss (AASHTO T96) and no more than 20 percent flat and elongated (F&E) particles when measured at a 3:1 ratio of length to maximum thickness (ASTM D
1.1 This test method covers the determination of the percentages of flat particles, elongated particles, or flat and elongated particles in coarse aggregates. Two procedures, Method A and Method B, are presented in this standard. Method A is a reflection of the original procedure as developed prior to Superpave and is intended for all non-Superpave applications.
