Saturated surface dry:
It is defined as the condition in aggregates in which the surface is dry but the inner particle void are saturated with water, this condition make no surface adsorption through aggregates.
It is defined as the moisture not retained or absorbed by the aggregates, also the moisture which can be removed by air drying.

Problem 2 Samples of coarse aggregate (CA) are collected at a stockpile and submitted for lab testing to determine their specific gravities. Tests were completed in accordance with ASTM C127-12 and the following masses are found: Mass Property 6,296 6,214 4,293 Mass of moist aggregate sample as submitted: Mass of oven-dried aggregate: Mass of aggregates submerged in water: Mass of SSD (Saturated Surface Dry) aggregate: 6,227 Using this data find the following: a) Aggregate bulk dry specific gravity b) Aggregate...
