Paving Principles &
Control Methods
This chapter describes the components of pavers and the basics in
paving principles, as well as control methods used for paving.
Paver Components
Modern pavers (Figure 2-1) consist of two major units: the Tractor
and the Screed.
The primary function of the tractor is to propel the truck or paver
feeding device, to convey and distribute the paving material and to
tow the screed. The function of the screed is to strike off the
material in preparation for further compaction. The screed is
mounted to the tow arms at the screed pivot points and is attached to
the paver at the tow points.
