Earthmoving machines play a vital role in highway construction. This article discusses some of the most important features of two earthmoving machines: the articulated dump truck (ADT) and the grader. Many companies are now offering an ejector body on their ADTs. The ejector allows material to be spread while the truck is moving and prevents material from adhering to the inside of the truck body after the dump. Ejecting a load without raising the body also increases stability so that the ADT can work on inclines and soft surfaces. Manufacturers are offering GPS based guidance systems for graders that allow machine operators to accurately perform earthwork operations by placing site design in the cab.
