Rigid pavement for helicopter parking
Rigid pavement for helicopter parking
(OP)
I have to design a concrete pavement for parking five bell 412 helicopters, approximately 350ft x 90ft. I'm considering 3500psi concrete (cyl), 6" thk, two layers of rft, upper #3 @ 12"BW, lower #4 @ 12"BW. The aft skid tube load is 4772lbs over a contact area 2"x14" i.e. imposed stress 199psi. The pressure to subbase material assuming 45 degree dispersion is 2045psf + concrete 75psf, total 2120psf < 3000 psf (safe assumption for the existing compacted subbase material). Any comments?
Fuel leakage needs to be giving consideration as present asphaltic surface is damaged. Also looking for guidance with respect to joint details and surface finish.
Any assistance will be appreciated.
Thanks

The FAA also has design guidance for aircraft - including helicopters. See http://www
