I've got a curb ramp at bottom of my driveway that I want to fill so I can drive up it without slowing. picture of ramp The usual fixes are to fill the dip with concrete, asphalt, lumber, a rubber ramp, metal ramp, or rubber/adhesive product (like curbramp.us). My town doesn't allow curb ramps, but rarely enforces the rule. The curbramp.us product is removable and is reasonably priced (about $155 for 14' long), but its rubber so probably needs maintenance. But that got me thinking -- could I just use a "road base" product (mix of gravel & crushed rock aka fines). I have no water running down my curb, it all drains away from driveway, so erosion from water not really a problem. As it wears away I suspect adding some road base then packing would fix. And if city made me remove the road base it would be easy. Anyone seen info on this?

    I would think the city would have problems with crushed rock as it will block the drainage and some will get washed away during heavy rains, also crushed rock will require maintenance it moves when you drive over it . – Ed Beal Jan 25 '18 at 20:22

    But aren't I looking at a drainage route here (from top to bottom or bottom to top)? Go out there during a rainstorm and study what happens in that area. It's important. – Harper - Reinstate Monica Jan 26 '18 at 3:33

    The other thing is that bump serves a public safety purpose, to slow you so you don't kill a kid -- oh wait, you wouldn't do that, and in any case you back out. So try backing in. Going in, you'll be switching to reverse right there, so moving very slowly. Coming out, you'll be doing your safety-stop/near-stop anyway. A genuine stop is required when coming off a driveway to a highway. – Harper - Reinstate Monica Jan 26 '18 at 3:38

If you use crushed rock or asphalt road mix, I would like to see you put a piece of perforated 2" Sch-80 PVC pipe at the bottom of the 'V' to catch and provide a conduit for run-off. The road mix is designed to react to pressure and heat. It would help if you could bring in a roller.

I like the rubber 'curb ramp' idea. I think it would be the most stable; and result in fewer down sides. A good engineering project would be to design and build a bridge. Build a interlocking trestle.
