E-4
M
Mat
The material being placed by a paver/finisher.
O
On-Grade
When a surface is at the selected elevation or slope, it is referred
to as being on-grade.
Overlay
Paving over an existing mat.
P
Percent (%) Slope
The unit of measure used for cross slope.
S
Screed
The assembly behind the tractor. The screed strikes off, smooths
and compacts the paving material into a semi-finished mat.
Slope
The incline of a paving surface perpendicular to the direction of
travel expressed by stating the rise or fall of a percentage of
horizontal distance (that is, 2% slope = 2" of elevation change in
100" of lateral run).
Slope Control
A means for controlling the transverse elevation of the fresh laid
mat in relation to the grade.
Slope Sensor
An electrical device which detects positive and negative change
in lateral elevation using the grade controlled side of the machine
as a reference.
