What is the compaction rate of asphalt?
It has been measured at 7.5% per hour. Most of the time is spent in the slowest sections of the truck. At speeds faster than 11 mph, the asphalt compaction rate is reduced to a point where the trucks reach the maximum recommended speed of 20 mph. On roads covered with ice and snow, trucks must slow to less than 6 mph so the compaction rate stays above the minimum of 10%.
How long does it take cold patch asphalt to harden?

How does temperature affect asphalt?
Temperature determines when the temperature exceeds the flexibility of the asphalt binder and the asphalt cracks. Warm asphalt is more flexible and more brittle than cold asphalt. As a result, cold asphalt generally has a longer life than warm asphalt. Cold asphalt cracks more easily than warm asphalt.
Hereof, how cold is too cold for asphalt?
Asphalt is typically designed for use between 0° and 50° (C), but the use of lower temperatures can result in cold cracks and rutting.
