Coarse aggregate apparent specific gravity. Degree of Saturation, S 1993 AASHTO Flexible Pavement Structural Design, 1993 AASHTO Rigid Pavement Structural Design, Climate Change Impacts on Pavements and Resilience, E-Construction in Practice: A Peer Exchange with WSDOT and TxDOT. Formula for void ratio | Degree of unsaturation calculator Specific gravity can also indicate possible material contamination. = Weight of soil solid in a given soil mass. The difference between Gsa, Gse and Gsb is the volume of aggregate used in the calculations. Q.3: Give the formula to determine the specific gravity (Gs). Slowly pour approximately 25 mL of soil sample from beaker into water in the graduated cylinder. The difference between these weights is the weight of absorbed water in the aggregates permeable voids. Specific gravity of solid = 2.65. i av = N d at middle of heave soil prism /unit length pile. This is because in the normal procedure the water may not be able to penetrate the pores to the center of the aggregate particle during the soaking time. Q.What is the deference between specific gravity and bulk density of If absorption is incorrectly accounted for, the resulting HMA could be overly dry and have low durability (absorption calculated lower than it actually is) or over-asphalted and susceptible to distortion and rutting (absorption calculated higher than it actually is). Now, Click on Soil Mechanics and Foundation underAgricultural, Now, Click on Bulk Density underSoil Mechanics and Foundation. Where SG = specific gravity, = density of the material (kg/m 3 ), W = density of water ( kg/m 3 ). w at 4C is 1gm/ml, 1000 kg/m 3 or 1 Mg/m 3 Basic Soil Relationships How to Calculate and Solve for Bulk Density | Soil Mechanics and If the sample is actually still wet on the surface then the mass of the SSD sample will be higher than it ought to be, which will cause a lower calculated bulk specific gravity. The formulas for calculating bulk density and particle density follow: Bulk density, b = mass of oven dry soil total soil volume Bulk density, b = mass of oven dry soil total soil volume Particle density, p = mass of oven dry soil volume of soil solids Particle density, p = mass of oven dry soil volume of soil solids Figure 8.1.
