Quantifying the Benefits of Improved Compaction

Compaction is the final and most critical step in asphalt pavement construction. National research conducted several years ago indicated that a slightly more compact pavement than typical could help roads last longer. To understand the relationship between pavement density and long-term performance, MnDOT has built a database with performance data from samples collected soon after they were constructed more than a decade ago. The agency hopes to eventually have enough data to determine the right amount of compaction.
