Asphalt Plant Technician Practice Test

The idea being tested is how a fine aggregate splitter should be designed to achieve a balanced, uniform flow. A splitter that feeds alternating sides works best when it is symmetrical: equal numbers of chutes on each side and those chutes having the same width. That symmetry ensures that, in aggregate, each side receives roughly the same amount of material, preventing one side from being overloaded or underfed.

Having a fairly large number of chutes—at least twelve total—helps break the flow into many small streams. More outlets mean the material can distribute more evenly across the split, reducing the impact of minor differences in chute wear, belt speed, or feed rate. The alternating-side design further promotes balance between the two streams downstream, aiding consistent moisture, binder distribution, and mix quality.

So, this statement is true because a properly designed fine aggregate splitter uses equal-width, equal-numbered chutes arranged to direct material to alternating sides, with a minimum of about twelve chutes to improve distribution uniformity.
