General

The asphalt distributor is the most complex piece of equipment used in seal coat construction work because it has many components, and all must be operating properly. An asphalt distributor is a truck-mounted, insulated tank, with numerous special purpose attachments. A typical asphalt distributor is shown in Figure 7‑3.

The major components are:
  • Asphalt tank
  • Heating system
  • Circulating and pumping system
  • Filter screens
  • Spray bar

  • Controls and gauges.
The inspectors should record the serial number and model of the asphalt distributor and enter this information in the project folder.
