Compaction is the single most important factor in the ultimate performance of a hot mix asphalt pavement. Achieving the proper air void content in the compacted mix makes the difference between a long-lasting asphalt overlay and one that fails prematurely, causing trouble and frustration for you (and your customer). This top-ranked session, by a highly-rated speaker, will help paving crews understand the basic elements of compaction and the use of various types of rollers, including static steel wheel, pneumatic tire and vibratory steel wheel rollers. Effective compaction of both stiff and tender hot mix asphalt mixtures will be covered. Further, the use of different rollers and rolling patterns for different paving situations will be emphasized.
