A walkway for a screed includes a main walkway and an extender walkway coupled to the main walkway and an extender frame of the screed. The extender walkway is slidable relative to the main walkway along a sliding direction. Further, the extender walkway and the extender frame are pivotable relative to each other about a walkway pivot axis, the walkway pivot axis being substantially perpendicular to the sliding direction.

Screed walkway

A height adjustment system for a paving screed apparatus and a method for adjusting the height of the endgates of a screed system are disclosed. In a disclosed system, the system includes an endgate coupled to a biasing element, such as a spring or a hydraulic cylinder and rod. The biasing element is coupled to an actuator. The actuator is linked to a controller. The biasing element is moveable between a compressed position and an extended position with a setpoint range disposed between the compressed and extended positions. The biasing element is also associated with a sensor for measuring vertical displacement of the biasing element, pressure or load on the biasing element with respect to the setpoint range.
