Trucking Ramp

[SuperRoe]

I am sarting a deep foundation project and I need to design a ramp for the entry and egress. Is there a standard slope used on ramps? I have a deep hole and not a lot of wiggle room. I need to know the max slope I can go and still have these trucks drive out with 23tons of ex.

My guess would be not to exceed the static coefficient of friction between rubber and concrete if you use concrete as the base material.

Not sure on trucks,
But I was just dealing with this issue for a tracked crane
and the answer was 1V:7H

chicopee,
Good guess, but don't forget about rain, the insitu soil that will be deposited on the surface, some oil seepage from the vehicles, and a comfortable factor of safety.

Or...ask an articulate truck driver with gray hair (LOL).

Typically 0.5% to 4% range is specified, but I agree with Michael. As an engineer, I would put much more stock in the advise of a trucker or trucking firm than that of an engineer.

If your firm has good relationships with any earthwork contractors and/or suppliers, give some of them a call. I would bet someone would be happy to advise for free, or over a complimentary lunch.
