Concrete block pavement is used as a modern pavement type owing to its economic benefits. The physical properties, mechanical properties, and functional characteristics of bedding sand and joint sand, the main components of concrete block pavements, should be accurately understood. Owing to the discontinuous structure of these pavements, load transfer efficiency (LTE) is the most important ...Asphalt Paving for Building Sites - Department of Transportation and ....1 Materials and installation for asphalt concrete pavement for car park areas, ... . 1 ASTM C88, Standard Test Method for Soundness of Aggregates by Use of Sodium ... .11 ASTM D2419, Standard Test Method for Sand Equivalent Value of Soils and ... .13 ASTM D4318, Standard Test Method for Liquid Limit, Plastic Limit and ...
Sand Equivalent Test Sets are used to indicate the relative proportions of clay-like fines in granular soils and fine aggregates. Gilson sets include everything required in ASTM and AASHTO test methods to conduct the test except the shaker. Both Sand Equivalent Sets include four Clear Plastic Graduated Cylinders, a Siphon Assembly, Irrigator Tube, Weighted Foot Assembly, Plastic Funnel, Solid ...Sand equivalent is used to test clay content, which is the percentage of clay material contained in the aggregate fraction that is finer than a 4.75 mm sieve. It is measured by ASTM D2419: Standard Test Method for Sand Equivalent Value of Soil and Fine Aggregate, or AASHTO T176: Plastic Fines in Graded Aggregates and Soils by Use of the Sand ...
sand and the total height of sand plus clay are read. The ratio of the sand height to total height, expressed as a percentage, is the sand equivalent value (Table 7). The ac tivity of the clay results in a magnificatjon in volume of the clay fraction which decreases the sand equivalent value (1).Aggregates for Concrete bination of gravels or crushed stone with particles predominantly larger than 5 mm (0.2 in.) and generally between 9.5 mm and 37.5 mm (3⁄ 8 in. and 11⁄ 2 in.). Some natural aggregate deposits, called pit-run gravel, consist of gravel and sand that can be readily used in concrete after minimal processing. Natural ...

ASTM D2419, 2014 Edition, June 1, 2014 - Standard Test Method for Sand Equivalent Value of Soils and Fine Aggregate This test method is intended to serve as a rapid fieldcorrelation test. The purpose of this test method is to indicate, under standard conditions, the relative proportions of clay-size or plastic fines and dust in granular soils and fine aggregates that pass the 4.75-mm (No. 4 ...200-1.5.4 Sand For Air-Placed Concrete. Sand for air-placed concrete shall be washed and conform to the gradation for portland cement concrete in 200-1.5.5. The amount of deleterious substances shall not exceed the limits prescribed in ASTM C 33. 200-1.5.5 Sand Gradations. The sand shall conform to the following gradations: TABLE 200-1.5.5 (A)
So if your sample has a 90 sand equivalent that means that 90% of the sample was good material and 10% was detrimental. If you have a 40 sand equivalent that means that 40% of the sample was good material and 60% was detrimental. Many materials such as concrete sands will have high SEs, in the 80s or 90s but it is very rare to see a 100 SE.5.2 A minimum sand equivalent value may be specified to limit the permissible quantity of claylike or clay size fines in an aggregate. 5.3 This test method provides a rapid field method for determining changes in the quality of aggregates during production or placement.
Testing the sand ( or sand equivalent, S.E. ) to determine the quality of aggregate used in road construction, concrete, asphalt and drainage layer, and it can be considered as supplement of Grading Test and practically to determine the total volume of sand to the soil ( sand, silt and clay ) and determining the water absorption of aggregate and inflation the result of this test is to ...4.4 Calculate the sand equivalent in accordance with Section 5.1. Note 6—If running the test in pairs, the two values should not differ by more than four points. 5.

Quality Testing of Sand at The Construction Site for The Concrete. There are different methods for testing the quality of sand at the construction site for concrete construction. The quality of the sand is as important as other materials for concrete. The most different, which passes through the 4.75 mm IS strainer, is known as the fine aggregate.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 equivalent value indicates that there is less ...
the presence of clays in the fine aggregate used to make concrete is detrimental to the structural properties of the concrete. the texas highway department currently uses the results of sand equivalent and loss by decantation tests as a means of detecting such clay and controlling the quality of fine aggregate used in portland concrete cement.DEPARTMENT OF TRANSPORTATION Use approved hot mix asphalt concrete mixtures that meet the following requirements other organic matter Ensure sand is free of clay lumps as determined by AASHTO T 112 and has a sand equivalent value exceeding 25 as determined by GDT 63 B Fabrication 1 Design procedures For all Superpave and 4.
