Transcribed Image Text:5.10 Samples of coarse aggregate from a stockpile are brought to the laboratory for
determination of specific gravities. The following weights are found:
Mass of moist aggregate sample as brought to the laboratory: 5,298 g
Mass of oven dried aggregate: 5,216 g
Mass of aggregates submerged in water: 3,295 g
Mass of SSD (Saturated Surface Dry) Aggregate: 5,227 g
Find
a. The aggregate bulk dry specific gravity
b. The aggregate apparent specific gravity
c. The moisture content of stockpile aggregate (report as a percent)
d. Absorption (report as percent)
Expert Solution
Step 1
Given:-
The following weights are found from the sample of coarse aggregates:-
Mass of moist aggregate sample brought to the laboratory = 5298 g
Mass of oven dried aggregate = 5216 g
Mass of aggregate submerged in water = 3295 g
Mass of saturated surface dry aggregate = 5227 g
To determine:-
c) The moisture content of stockpile aggregate
d) Absorption
