The compaction effort or number of gyrations of compaction at design (ndesign) for the superpave™ compactor is varied to allow for different levels of in the laboratory, the asphalt mix is compacted against a solid foundation, whereas in the field a variety of base types and stiffnesses are encountered.

About 27% of these are compactors, 29% are road rollers.

After asphalt pavement is laid down, the density is traditionally measured using point sampling methods such as coring, a nuclear density gauge, or a pavement quality indicator (pqi).
