Feeling the Heat: The Central Role of Temperature in Asphalt Paving

This article describes the central role of temperature in asphalt paving, focusing on strategies for maintaining the asphalt product within the right temperature range. Topics covered include maximum mix temperature, differences between hot mix asphalt (HMA) and warm mix asphalt (WMA), heat loss during truck transport, the interplay of temperature and long-term performance life of the road, minimum mix temperature, problems with compaction of too-cool asphalt, the role of ambient temperature (and why it’s better to pave on hot days rather than on cool days), the existing pavement temperature (also a role of the ambient temperature), and the interplay of temperature and compaction.
