acceptable road gradients
acceptable road gradients
(OP)
I have a client who would like to build his house on a site with a very steep access. Looking at the topo-cadastral map the only possible route has a gradient in the region of about 1:3.5 Is this too steep for a driveway? the length of this section would be about 100m





RE: acceptable road gradients
(I assume from your ID that you are in Southern Africa/Swaziland so I don't suppose you'd otherwise have too much of a problem with ice/snow).
RE: acceptable road gradients
Yep, in Swaziland, so no ice or snow

but you'd certainly need some sort of flatter area (1:5 say) where the private road joins the public highway (and where nervous drivers can stop and let their brakes cool).
I can't see you getting any sort of service vehicles up there either (do you have tracked refuse lorries?), never mind constructing the thing (e.g. laying bitmac at 1:3).
