axtm It is recommended that the desiredprocedure be reviewed carefully prior to conducting the test. The granular base is typically dense graded, with the amount of fines limited to promote drainage. The apparatus consists of a stainless steel hopper, stand, measure and strike-off bar and a mm square glass plate for calibration of the measure.

Currently, the ConnDOT specification allows for no more than 10 percent flat and elongated particles f4791 a 3: Plunger is mounted on support stand, permitting plunger to lower and raise freely. Periodically, inspect e4791 width greater than a specific value. Granular subbase is also f4791 graded, but tends to be somewhat more coarse than granular base. The standard flat and elongated particles in coarse aggregate test is: Coarse aggregate angularity requirements do not apply.


These instructions are a general guide for operation of this. Two procedures, Method A and Method B, are presented in this standard. When required, weighted average percentages based on the actual or assumed proportions of the various sieve sizes tested.

Method A is a reflection of the original procedure as developed prior to Superpave and is intended for all non-Superpave applications.


The excess heaped aggregate is struck of using the included bar, the mass is measured, and the void content is computed. Aggregate base course shall be accepted for density on a lot basis. This test method covers the determination of the percentages of flat particles, elongated particles, or flat and elongated particles in coarse aggregates.

Percentages, asrm by mass awtm flat and elongated particles, for each sieve size tested, and the combined aggregate percent for flat and elongated particles. Particle d elongated when its length longest dimension is more than 1.
