You can technically go up to 8.33% on a ramp run but Caltrans and SB County and many other agencies have now changed to 7.5% max. You should really design a ramp, if all possible, no steeper than 7.5%. With a simple little field change it does not take much to be over 8.3% and if this happens, it gets very costly with removal and reconstruction.

This video is spot on, I'll be watching it a few more times. I've stayed very busy replacing ramps that are non compliant because contractors attempted to build them at or very near the maximum slopes. With inspectors and civilians hungry for lawsuit money all inspecting with a 2' smart level, no one will ever design and execute a ramp at 8.33 and a crosslope of 2 that will pass. So smart to designate "design parameters at 7.5 and 1.5. I typically set up my ramps at 6 percent and 1% crossslope just to give room for finishers that might need to move more quickly on a busy pour. Of course that's if the situation allows.. These days if I'm asked to build a ramp with only room for 7.9% I'll refuse.. it's a recipe for failure. Looking foward to more videos. And digging deeper into this one here, it's very inclusive to a variety of ramps! Thanks!

You are welcome. I wanted to start off with a good foundation and move onto doing the design using Civil 3d. Ramps can sometime be challenging.
