Concrete Pavement on Slope
Concrete Pavement on Slope
(OP)
Hi guys,
I have a concrete pavement on a 1:3 grade and I'm a little concerned about the slab sliding, similiar to a retaining wall sliding due to active earth pressure.
Has anyone designed a concrete pavement on such a steep slope and did they use any general design principles such as providing a shear key or other form of mechanical resistance.
Also, is this sliding the only failure mechanism that can be developed or should I be looking at a global failure surface as well.
The slab is a residential driveway but I have been requested to make allowances for heavy traffic.
If anyone can point me towards any reference material than that would be greatly appreciated.

(down around UFC 3-250).
i've used a detail before for thickened edge/construction joint that worked well but i can't recall the exact manual it came out of. basically, it was a thickened edge that acted as a key.

The slope is 1:4, I wanted to dramatize this in the hope of recieving a wider response.
I've done some statical equilibrium numbers to satisfy myself this pavement won't slide because of the friction at the concrete-soil interface. I haven't had much experience with pavement design so I wanted to know what are the commonly used techniques when constructing pavements on steep grades.
I'll research into soil nailing, slope stability, re-grading and texturing the wearing surface.
Thanks all for your replies.
