What is the minimum rolling temperature required for effective compaction?

The minimum rolling temperature required for effective compaction of asphalt is typically around 175 degrees Fahrenheit. At this temperature, the asphalt has the appropriate viscosity, allowing it to be worked and compacted effectively without causing damage or inadequate bonding between the aggregates. Compaction at this temperature ensures that the mixture is pliable enough to achieve the necessary density and structural integrity once it cools down.

If the temperature is lower than 175 degrees, the asphalt may not compact properly, leading to issues such as a weak pavement structure, decreased lifetime of the surface, or increased susceptibility to damage from environmental factors. Therefore, maintaining this temperature range is critical to achieving optimal results in road construction and maintenance.
