Task G-22 Prepares and builds roads
Task Descriptor
The first step of road construction is to prepare earth for the right of way. Construction craft workers work with machines to place and compact sub-base, base and surface materials. They manually spread, shovel and rake asphalt where the machines cannot operate. They also apply adhesives and primers and modify and repair all road surfaces.
