Specific gravity of crushed stone base

Specific Gravity is the ratio of the weight of a given volume of aggregate to the weight of an equal volume of water. Water, at a temperature of 73.4 F (23 C) has a specific gravity of 1. Specific Gravity is important for several reasons. Some deleterious particles are lighter than the good aggregates

Dec 16, 2019 Most normal weight aggregates have a bulk specific gravity SSD between 2.5 and. 3.0. Different types of specific gravity are commonly used depending upon how the volume of water permeable voids (or pores) within the aggregate are addressed. Apparent Specific Gravity, Gsa. Bulk Specific Gravity (Bulk Dry Specific Gravity), Gsb

Aug 12, 2011 The specific gravity of all other materials are compared to water as a fraction heavier or fraction lighter density, no matter how small or large the fraction is. For example, ammonium nitrate has a specific gravity (sg) of 0.73 while dry ammonium sulphate has a

Equation 7.36 is based on a rock riprap specific gravity of 2.65, and a stability factor of 1.2. Equations 7.38 and 7.39 present correction factors for other specific gravities and stability factors. Csg = 2.12/(Ss - 1) 1.5 (7.38) Where: Ss = the specific gravity of the rock riprap Csf = (SF/1.2) 1.5 (7.39) Where:SF = the stability factor to be

As specific gravity is just a comparison, it can be applied across any units. The density of pure water is also 62.4 lbs/cu.ft (pounds per cubic foot) and if we know that ammonium nitrate has a sg of 0.73 then we can calculate that its density is 0.73 x 62.4 = 45.552 lbs/cu.ft

Jun 09, 2005 But you need to touch base with someone who has local experience. RE: Aggregate Base Density Data BigH (Geotechnical) 28 May 05 14:03. JedClampett - sorry, but we have compacted crushed stone coming in at over 150pcf. Why? Our specific gravity is 3.0. I agree with you. M076 can look in tables of swell/shrink on variouis materials from bank to
