Abstract
This article describes how to achieve optimum compaction when constructing hot mix asphalt (HMA) pavement, which plays a critical role in the the useful life of the pavement. Improper compaction can result in pavement deterioration -- poor processes can lead to accelerated aging due to decreased pavement stiffness, reduced durability, raveling, and moisture damage. The author highlights the two most important factors in compaction: use of the vibratory screed on the paver in vibrating mode; and mix temperature during compaction. The article details the steps for proper compaction, to ensure a durable, long-lasting pavement.
