What is the process for transporting the HMA from a facility to usage at the paving machine?
The Hot Mix Asphalt is transported via dump trucks to the paving machine on the construction site. The trucks dump the hot HMA into the hopper on the front of the paving machine. As the paving machine drops the pavement on the ground, workmen known as “luteman/rakers” spread the HMA quickly in place so the heavy roller machine can be driven over the fresh pavement before the temperature of the HMA drops below 175-degrees Fahrenheit…the lowest temperature at which compaction can take place to meet the specified compaction density. Traffic is generally permitted on the pavement immediately following compaction.
