MIXING AND COMPACTION TEMPERATURES FOR HOT

However, some modified binders have exhibited unreasonably high temperatures for mixing and compaction using this technique. These high temperatures could result in construction problems, asphalt damage, and fume production. ASTM D 2493 was established for unmodified asphalt binders, which are Newtonian fluids at high temperatures.
