From delivery of HMA at a site to finish rolling, every asphalt paving project involves a choreographed sequence of responsibilities. Given that the time available for compaction (TAC) can be as little as 10 minutes in some circumstances, the role of each paving crew member is extremely vital to a successful HMA project.

The following are general descriptions of each of the main crew positions on a typical HMA project.

Truck driver
Put simply, the truck driver's role is to make sure the HMA gets from the pug mill (i.e., mixing drum) to the paving operation efficiently. But there's more to the task than merely driving. The driver must first load the truck, making sure to use at least three load placements to ensure a homogenous mass and to avoid segregation of the mix. 

Once on the site, the driver backs the truck into position and aligns it with the material transfer vehicle (MTV), paver or windrow. As the paver or MTV moves forward and makes contact with the truck or trailer tires, the truck driver opens his tailgate and discharges the mix. He will then follow the instructions of the dump person, the paver operator or MTV operator as he adeptly inches his truck forward in sync with the equipment behind him. With his load delivered, the truck driver pulls away, cleans any residue from his vehicle and returns to the plant for another load.
