Consider a sediment sample that is half sand, half gravel (here loosely interpreted as material coarser than 2 mm). Plotted with a logarithmic grain size scale, the sample is correctly seen to be half sand, half gravel. Plotted using a linear grain size scale, all the information about the sand half of the sample is squeezed into a tiny zone

The basecourse aggregate shall comply with either Sand Equivalent or Clay Index or Plasticity Index requirement stated below. 220.127.116.11 Sand Equivalent The sand equivalent shall not be less than 40 when the aggregate is tested according to NZS 4407 : 1991, Test 3.6 Sand Equivalent Test.
After agitation and settling, the sand separates from the clay-like fines and the heights of sand and sand plus clay are measured. The SE value is the ratio of the height of the sand and sand + clay times 100. A higher sand equivalent will be obtained for cleaner aggregate.

The contractor must exercise control over the following properties: asphalt content, gradation, air voids, VMA, VFA, CAA, sand equivalent, FAA, TSR, density, and dust-to-asphalt ratio. Samples for mixture properties, aggregate gradation, and binder must be taken from behind the paver and transported to the field laboratory for testing.
4.1.5 Secure the sand equivalent test sample from the portion passing the No. 4 (4.75 mm) sieve by carefully reducing the amount of material to laboratory test size. 4.1.6 Split or quarter the material to obtain a minimum 18-oz. (500-g) sample.
(2) For crushed sand this is allowed to decrease to 75 to 90. (3) For crushed sand this is allowed to decrease to 90 to 100. The joint sand will be subjected to the sand equivalent test (Test Method Tex-203-F). The sand equivalent shall not be less than 35 unless otherwise shown on the plans.
SAND SPECIFICATIONS: Washed ASTM C33 Fine Aggregate Concrete Sand is utilized for stormwater management applications in Montgomery County. In addition to the ASTM C33 specification, sand must meet ALL of the following conditions: 1. Sand must meet gradation requirements for ASTM C-33 Fine Aggregate Concrete Sand.
WSDOT Errata to FOP for AASHTO T 176 Plastic Fines in Graded Aggregates and Soils by the Use of the Sand Equivalent Test WAQTC FOP for AASHTO T 176 has been adopted by WSDOT with the following changes: Sample Preparation Replace step 7 with below: 7. WSDOT requires two samples.
sand equivalent test for control of materials during construction. a test method is presented which provides a rapid method for detecting the presence or absence of detrimental fines or clay-like materials in soils and mineral aggregates.

For all classes of concrete except Class K, provide fine aggregate with a fineness modulus
Sep 01, 2013· The sand equivalent test quantifies the relative abundance of sand versus clay in soil. It is measured by standardized test methods such as ASTM D2419, AASHTO T176, and EN 933-8. The test is used to qualify aggregates for applications where sand is desirable but fines and dust are not. A higher sand ...
Sand Equivalents According to Caltrans' test method 217-Sand Equivalent, "The sand equivalent test provides a measure of the relative proportions of detrimental fine dust or clay-like material in soil or fine aggregates."
