How does an under compacted pavement's performance life compare to properly compacted pavement?

An under compacted pavement has a performance life that is decreased when compared to properly compacted pavement. Proper compaction is crucial to achieving optimal density and stability in asphalt mix. When the pavement is not adequately compacted, it can lead to issues such as reduced structural strength, increased susceptibility to moisture infiltration, and early deterioration due to the inability to withstand traffic loads effectively.

Additionally, the voids present in under compacted asphalt can lead to premature cracking and raveling, as the mix is not fully consolidated. These conditions ultimately result in the need for repair or rehabilitation much sooner than would be necessary for a properly compacted surface. Therefore, understanding the importance of compaction in the context of pavement performance is essential for ensuring longevity and effectiveness in asphalt infrastructure.
