D41 41
First method:
1. When laying the first layer,
lay the asphalt until the
screed almost touches the
manhole. Then raise the
screed and drive over the
manhole.
2. Lower the screed on the
other side of the manhole.
3. Spread the material left by
the raised screed around
the manhole and level it off.
Alternative:
1. Use a piece of timber or
make a flat ramp of asphalt
on both sides of the
manhole.
2. When the wear course
is laid, the screed rides
up on the ramp and passes
over the manhole.
3. This process should be
carried out with the paver
finisher moving at slow speed to give the screed and the levelling system time
to react.
