Construction 4 - Specific Gravity

Bulk Specific Gravity of Aggregates (Paving Mixture)

P - percent weight
G - specific gravity

Effective Specific Gravity of Aggregates (Paving Mixture)

P_T - total asphalt mixture = 100%
Pa - percent weight of asphalt cement
G_mm - max. specific gravity
G_a – specific gravity of asphalt cement

Asphalt Absorption of Aggregates (Paving Mixture)

P_T - total asphalt mixture = 100%
Pa - percent weight of asphalt cement
G_b-agg - bulk specific gravity
G_e - effective specific gravity
G_a – specific gravity of asphalt cement

Max Pressure in Slump Concrete

P - max lateral pressure in Slump Concrete (lb/ft²)
R - rate of placement (ft/h)
T - temperature of concrete form (F)

Open & Close Pores

V_W = Open Pores
V_T - V_S - V_W = Close Pores
