Question 1
According to ASTM C136/C136M, what is the primary reason for performing a sieve analysis on fine and coarse aggregates?
Correct Answer:
To determine the particle size distribution (grading) of the aggregate
Question 2
A technician is tasked with determining the bulk density (unit weight) of a coarse aggregate sample by rodding, in accordance with ASTM C29/C29M. The procedure involves placing the aggregate into a calibrated measure in how many approximately equal layers?

Question 4
A laboratory is testing a coarse aggregate sample for specific gravity and absorption according to ASTM C127. The aggregate is soaked for a prescribed period and then dried to a saturated-surface-dry (SSD) condition. What does the SSD condition signify?
Correct Answer:
The aggregate's permeable pores are filled with water, but the surfaces of the particles are dry.
Question 5
When an accurate determination of the material finer than the 75-µm (No. 200) sieve is required for an aggregate sample, ASTM C136 states that dry sieving alone is insufficient. Which test method should be performed prior to the dry sieve analysis?

ASTM C117 (Materials Finer than 75-µm Sieve by Washing)
