Warm asphalts are asphalts produced at significantly lower temperatures than the C that is typical of a hot mix plant. Depending on the approximately 160 technology used, laying and compaction may also be possible at significantly reduced temperatures.
The report gives a summary of current warm asphalt technologies, followed by details of costs, temperature reductions and energy savings. A comparison is made of potential environmental costs and benefits of hot mix manufacture and the different warm mix methodologies.
