Driveway angle or pitch.

CAB,

Here in vegas, the max driveway slope is 12%. Grwanted this does not include the slope of the sidewalk (2%) or the 5' landing in front of the garage door (also 2 %). Maybe that will help some.

CAB,
This question has been discussed a few times at eng-tips, although you guys have hit on the main points. One thread is at http://www.eng-tips.com/viewthread.cfm?SQID=72147&SPID=158&newpid=158&page=1

Thanks for the info rug.

Carl, the site is down so I'll try again later.

On the ramp to an undergroud car park we designed a few years back we used transition curves at the top and bottom of the ramp. The slope was 16.6% or approx. 1 in 6 and the radius of the arc for the transition curve was 15m. This suited our european size cars but may not be enough for the leviathans you guys drive!!

Thats great.. :)
I drive a one ton dually myself.

I think the transition curves you mentioned is the way to go.

I did find more info on driveways, see the link to pdf file.

kate,
where is that photo from? Is it a real driveway?

I actually saw another photo, different view of the same driveway

Pieter,

I got it (and two others, maybe one of them is the same as yours) from a friend of mine, who got it from a co-worker, who got it from...I also got it from my boss, under different file names... :-) I think they've just been floating around.

That's about the story on this end as well.
We were debating if it was indeed a true driveway that was built
and not photo-edited to look that way.
Some people are very creative with photoshop type programs
and it is hard to tell sometimes...

Yes, those are real pictures.  I got a confirmation from the design group involved, out of Ventura, California.  I don't think they would want me to give their name.  The designer's defense was it was the developer's fault.... They told us they didn't care what it took ( I think the quote was "even if we need to build a funicular") the earthwork had to balance.

California huh? Is the name DMB? We've bought a nightmare of a piece of land recently that has alley loading back-of-house driveway/garages. The driveways aren't so bad, but the land was developed in such a way the at about halfway down the lot, the land drops straight down or up 2'. That's a nightmare to design for.
