2012-4-26  As a result, the mixing and compaction temperature for modified asphalt can be determined to deliver 0.17±0.02Pa⋅s and 0.28±0.03Pa⋅s for HMA mixing and compaction, respectively. The difference between temperatures obtained with the methodology and temperatures at which optimal compaction effect can be obtained is less than 5°C.

Summary Mixing and Compaction Temperatures of

However, selecting appro- priate temperatures for handling these binders has been an issue with the use of modified asphalt binders. The traditional method of determining appropriate mixing and compaction temperatures for an asphalt binder is based on relatively simple viscosity measurements of the asphalt.
