Why Tracking Temperatures is Key to Successful Asphalt Paving

Aug 16, 2011 · Why Tracking Temperatures is Key to Successful Asphalt Paving. Hot mixed asphalt is manufactured at temperatures between 270°F and 325°F. Depending on the environmental conditions and the distance from the hot mix plant to the project, hot mix asphalt can lose between 5°F and 25°F.

Relationship of Paving Asphalt Temperature Susceptibility ...

der if temperature susceptibility for paving asphalts could be based on penetra-tion at 25 C (77 F) and viscosity in centistokes at 135 C (275 F). This paper will attempt to show that PVN is the most useful measure of paving asphalt temperature susceptibility that has been proposed so far.
