Asphalt Plant

Asphalt mixing plants heat aggregates and mix them with bitumen and other adhesive substances to generate hot mix asphalt (HMA). The quantity and nature of the aggregate depends on specific requirements of the mix which are defined by the contractor for the application.  Requirements can range from single-sized material to various sizes of fine and coarse particles.

Transportation

Transporting material from the plant to point of application is a critical time for temperature loss.   Factors such as air temperature, rain, wind and length of haul can affect the characteristics and temperature of the load. Specific measures can be taken to minimize HMA cooling during transport, including minimizing the haul distance, insulating truck beds, and tarping the bed.

Paving, Sealing, and Repairs

Screed temperature and ground temperature are two critical factors that should be considered before laying down HMA onto the pad. If they are out of acceptable zones, quality paving will be compromised. IR thermometers are ideal tools for performing this task.

For sealing and repairs, maintaining the optimum temperature of the hot tar in the tank is critical to proper flow, adhesion, and safety.

Quality Check

The final temperature check of the pad should always be done right before the roller performs the compaction. Rolling should be completed before the surface temperature of the mix falls below 240° F. Tel-Tru spot check thermometers provide the reliability and accuracy needed for this final step.
