Paving City Streets with Cross Slope

P-32+ and P-32 Operator’s Manual P/ N: 1001547-01
A cross section design of a 36 feet wide street with a 2.0% slope produces a 36 feet rise at centerline
(Figure 136).

If the curbs are at different elevations, a 36 feet rise at centerline produces incorrect slopes (Figure 137).
Figure 137: Curbs with Different Elevations
When using your Topcon P-32+ or P-32 System to pave a true 2.0% slope, the crown of the street will not be
at the centerline (Figure 138).
