NOTICE
Temperature problems may occur will before the
time the material is loaded into the trucks, or
during the trip to the paver. They can be the
result of temperature variations at the plant. If
this is not addressed prior to delivery of material
to the paver, waviness in the he mat will be the
result.
Weight of Screed (“W”)
For the weight of screed force “W” to remain constant, the
weight of the screed or the downward pressure exerted by the
screed on the paving material should not change (Figure 2-13).
The weight of the screed is measured in pounds per square inch.
Figure 2-13. Weight of Screed
Members of the paving crew climbing on and off the screed
will also have some affect on the weight of screed force.
