Hi,
I posted this thread in AASHTO forum & hope to get some feedback here.
I'm planning to build a short span ramp to allow a 40 foot trailer to climb 10 feet.
Initially, I suggested 2:1 H:V or 50% climb & the reaponse was no. What if I lower the gradient to 3:1 or 4:1 ? The climb would be 33% & 25%. Both gradients exceed the maximum gradient allowed in AASHTO green book of 15 % climb.
Any thoughts?
I just need a ramp short enough for the climb. There will be sufficient distance before approaching the ramp.
thanx
