Thanks, f-d and Richard. Fyi, the site slopes less than half a percent. I am concerned that the subgrade will probably saturate, since winters are pretty rainy here. I will spec the geotextile for sure. Thanks again.

Sorry for the skimpy info, I was in a hurry.
The site will be used for pipe storage, with alleyways for equipment access, and bunks for pipe to be stored on. The bunks will probably be railroad ties, to raise the pipe above ground enough for the forklifts to stack and retrieve it. It will not...
I have a client wanting to develop industrial storage on a site with groundwater less than 1.5' below the surface. Soils are sandy loam, AASHTO class A-4. Where do I find guidance on a minimum surfacing structural section?
AASHTO calls for 60% of the superelevation to be acheived at the PC or PT, thus by implication typically 40% of the super transition is within the curve. Thus super transitions for reverse curves are different only by amount acheived at that point.
I would use minimum transition length, and...
Depending on availability and cost, an option you might consider is using asphalt grindings rather than crushed rock for a section of the road. We obtained grindings at approximately the same cost as top rock, and the dust reduction was amazingly good.
