How Is Tar & Chip Installed?

After the prep work is completed (which is almost identical for tar & chip paving, as it is for asphalt paving)

First a coat of liquid A/C is applied to the existing surface. This is accomplished by using a computer-controlled distributor truck equipped with spray bars, to apply an exact and consistent amount of liquid A/C, heated to the right temperature.

Then a clean, crushed chip stone is spread using a spreader box attached to the dump truck transporting the gravel. The stone adheres to the hot liquid asphalt

Finally, a roller is used to embed the stone into the tar. The entire process is repeated on jobs where multiple courses are required
