This article is the first in a three-part series that discusses the three most critical operations in building a well-performing hot mix asphalt (HMA) pavement: pavement compaction, longitudinal joint construction, and segregation management. This first installment focuses on pavement compaction, which may be the single most important factor that affects the ultimate performance of the pavement under traffic. The author stresses that compacting an asphalt pavement to an air void content of 6% or less generally increases the fatigue life, decreases the amount of permanent deformation or rutting, reduces the amount of oxidation or aging, decreases moisture damage or stripping, increases strength and internal stability, and may even decrease slightly the amount of low temperature cracking that may occur in the mix. The author discusses the compaction of stiff mixes, conventional roller combinations, alternative roller combinations, tender mixes (including their compaction), and temperature zones.
