Determining Lab Mixing and Compaction ... - Asphalt Institute

Asphalt Institute Technical Advisory Committee. Approved 7 December 2016. The Asphalt Institute recommends that, for unmodified asphalt binders, the laboratory mixing and compaction temperatures should be determined where the viscosity-temperature line crosses the viscosity ranges of 0.17 ± 0.02 Pa-s (mixing temperature range) and 0.28 ± 0.03 Pa-s (compaction temperature range).
