When paving with Hot Mix Asphalt in cold weather, the goal is to finish compacting the mix while it is still in the compaction temperature range of 275° to 175°F. To allow adequate time for compaction, take steps to alter dependent variables and to minimize the time of exposure of the mix between mixing and compaction.

Asphalt paving projects utilize hot-mix asphalt, so it is not ideal to pave in the winter. Hot-mix asphalt must remain hot to compact and perform properly. If the ambient and ground temperatures are too low, they will chill the hot-mix asphalt while it is in transport from the production plant to your property. This is not good.
