For coarse aggregate, the splitter will have an equal number and equal width of chutes, at least 8, which shall be at least 25% greater in width than the largest particle size.

• A. True
• B. False
• C. Only for fine aggregates
• D. Not specified

Answer: (B)

Splitters for coarse aggregate are designed to divide a sample into multiple equal portions so the test results are representative. The important points are that the device uses multiple outlets that are identical in size and have a sufficient number of outlets—eight or more—to ensure random, even splitting. The key is that the outlets must be wide enough to allow the largest particle to pass without jamming. The specific requirement of “at least 25% greater in width than the largest particle size” isn’t a standard specification, so that particular width ratio isn’t correct.
