REFERENCED DOCUMENTS. 2.1 AASHTO Standards: • M 231 Weighing Devices Used in the Testing of Materials 2.2 ASTM Standards: • D 2726 Test Method for Bulk Specific Gravity and Density of Non-Absorptive … WebSpecific gravity (S.G.) is a measure of the relative density of a substance as compared to the density of water at a standard temperature. Physicists use 39.2 F (4 C) as the standard, but engineers ordinarily use 60 F. In the International System of Units (SI Units), the density of water is 1.00 g/cm 3 at the standard temperature.
Coarse Aggregates in Construction Types and Uses
WebThe specific gravity of aggregates normally used in construction ranges from about 2.5 to 3.0 with an average value of about 2.68. Specific gravity of aggregates is considered as … WebTypical values for bulk specific gravity range from 2.200 to 2.500 depending upon the bulk specific gravity of the aggregate, the asphalt binder content, and the amount of compaction. Absorption should typically be below 2 percent. If more than 2 percent water by volume is absorbed by the sample then this method is not appropriate. thomas yap
