The standard sand equivalent test is: AASHTO T 176: Plastic Fines in Graded Aggregates and Soils by Use of the Sand Equivalent Test; ASTM D 2419: Sand Equivalent Value of Soils and Fine Aggregate; Background. Excessive dust or plastic fines (clay-like fine particles) in HMA aggregate can contribute to a lack of stability (rutting or shoving) or moisture damage and stripping.
• Higher sand equivalent values indicate “cleaner” (less fine dust or clay-like materials) aggregate. • Typical sand equivalent values range from less than 30% to more than 90%. • If agg. #1 has SE = 70% and agg. #2 has SE = 40 % that means agg. #1 has more sand and less clay like material than agg. #2.

The sand used was a high quality concrete sand which was washed in the laboratory with a detergent to remove all minus 200 mesh material.
It was found that the sand equivalent values are continuously decreasing from 84 to 14% in the fraction 0/2 mm and from 87 to 18% in the 0/4 mm fraction, with increasing of the methylene blue
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.
Apr 30, 2011· 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.

Jan 31, 2014· The sand equivalent value is calculated as follows: SE = H S H c × 100. A higher sand equivalent value indicates cleaner fine aggregate (i.e. lower clay particles). However, results obtained by Gaynor on 130 samples indicated that there was little correlation between the minus 75 μm material content in a sample and the value of sand

Reference Table for "U" Values "U" Value is the coefficient of transmission, i.e., the transmission of heat through the materials, which compose the building's "envelope," or outer shell. "U" Value has an inverse relationship to "R" Value. For example, a building with material with an "R" Value of R-11 converts to an "U" Value of 0.09 ( 1/R or 1/11 = 0.09).
ASTM's cement and concrete standards are instrumental in the evaluation and testing of concrete, cement, and aggregates. Concrete can have different properties depending upon the mixture that is used in creating it, which contains cement, chemical admixtures, and aggregates.

Overview. The Los Angeles (L.A.) abrasion test (Figure 1) is a common test method used to indicate aggregate toughness and abrasion characteristics. Aggregate abrasion characteristics are important because the constituent aggregate in HMA must resist crushing, degradation and disintegration in order to produce a high quality HMA.. Figure 1: L.A. abrasion testing equipment.

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.
