Applicability |
|
Porous paving is a replacement
for conventional hard paving surfaces provided that slope, infiltration
rate, ground water table conditions and subsoil drainage characteristics
are suitable. This alternative method of paving is most successful
in pedestrian and bicycle areas, light traffic areas such as overflow
parking, and road shoulder areas. The slope should be less than 5%,
and the infiltration rate should be at least .25 inches per hour.
The minimum depth to bedrock and seasonally high water table should
be at 3 feet. |
