Road Construction
|
|

There are a number of important issues to remember as roads
are constructed. Some of these are illustrated in the drawing below.
|
|
- The angle of the cut slope should be kept as low as practical to reduce
the possibility of sloughing or slipping.
- As the road base is being formed, the fill material should be compacted
as construction occurs. Keep stumps and woody debris out of the road
base. This type of material will deteriorate and leave voids in the
fill which will subsequently collapse and damage the road.
- The roadbed should be formed for the appropriate design as the cut
or fill is being made. Inslope, outslope or crown will allow the road
surface to shed water. Remember, standing water causes most maintenance
problems with road surfaces.
- Trees and shrubs should be maintained at the base of the slope. This
vegetation acts as a filter to absorb the sediments from storm runoff.
The vegetation also serves to stabililze the bottom of a fill slope.
- Drainage features include ditches, cross culverts and rolling dips.
These features abate the problem of excess runoff on the uphill side
of a road.
