The following questions are typical of the types of items that are on the examination. The correct answer is highlighted.
1. When the soils report indicates that compaction of a trench will result in 10% less volume, what should be expected during backfill?
Fill will have to be exported.
Soil will have to be imported.
Water will need to be added to increase compaction.
More asphalt will be needed during resurfacing.
2. If a 12', 45-degree offset is required when laying a pipeline, how much extra pipe is required in order to avoid the obstruction?
3. According to OSHA, what should be the minimum distance between ladders inside a trench that is 4' or deeper?
