Sand Equivalent Value: The sand equivalent test is a rapid field test to show the relative proportions of fine dust or clay-like materials in fine aggregate (or granular soils). Test Method: MORTM, IS: 2720 (Pt-37)1976, ASTM D 2419-2009. Soundness: This test helps in determining the resistance to disintegration by freezing and thawing.

The term " sand equivalent " expresses the concept that most granular soils and fine aggregates are mixtures of desirable coarse particles, sand, and generally undesirable clay or plastic fines and dust. Note 1—Some agencies perform the test on material with a top size smaller than the 4.75-mm (No. 4) sieve. This is done to avoid trapping ...

In the United States, sand is commonly divided into five sub-categories based on size: very fine sand ( 1⁄16 - 1⁄8 mm diameter), fine sand ( 1⁄8 mm - 1⁄4 mm), medium sand ( 1⁄4 mm - 1⁄2 mm), coarse sand ( 1⁄2 mm - 1 mm), and very coarse sand (1 mm - 2 mm).

Sand Equivalent Value. The analysis of soils by particle size provides a useful engineering classification system from which a considerable amount of empirical data can be obtained. Two separate and different procedures are used. Sieving is used for gravel and sand size particles and sedimentation procedures are used for the finer soils.

Fineness modulus of sand (fine aggregate) is an index number which represents the mean size of the particles in sand. It is calculated by performing sieve analysis with standard sieves. The cumulative percentage retained on each sieve is added and subtracted by 100 gives the value of fineness modulus. Fine aggregate means the aggregate which ...

Overview. The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting. Figure 1: Fine aggregate angularity test.
