The goal of compaction is also known as what?

• A. Compaction Density
• B. Paver Staging
• C. Roller Pattern
• D. Surface Planing

Answer: (C)

The main idea is that achieving a dense, uniform asphalt mat is reached through a planned way of rolling. The phrase roller pattern refers to the specific sequence, overlap, and technique you use when the rollers move to compact the pavement. That pattern is what you design to reach the target density across the entire surface, ensuring even compaction and a stable mat as the asphalt cools. The density you ultimately want is the measurable outcome of following the right roller pattern.

Think of it this way: compaction density describes the result you’re aiming for, but roller pattern describes the process you use to get there. Paver staging and surface planing are different activities—where you place the paver or removing/planing a surface, respectively—and aren’t describing the goal of compaction.
