I have a sloping garden path on which I run a wheelchair. The path is 100mm deep composed of 40mm and smaller base aggregate (but no fines) with a blinding of 3mm sand, compacted with a wacker. The result is reasonably good for a wheelchair, but when it rains hard the sand washes downhill. Can I stop this happening? Perhaps by mixing the sand with a weak cement mixture? Or is that a waste of time? Would it be better to remove the top 50 mm and lay paving slabs? Thanks

Hard pave it, yes.

how long is the ramp and at what gradient?
i am pretty sure the latest regs suggest a 1:20 gradient with flat rest areas every 4.5 M
also tactile slabs and a hand rail are a must
(these are the pressed concrete slabs with ridges on them)

For personal use, a few cheap flags would be the lowest cost option, but a concrete surface (100mm deep) would be easier to install. However, with concrete, you really do need to stay off it for at least 5 days, whereas you can traffic flags within 24 hours, if not sooner.
Gravel is not considered to be a suitable surfacing material for disabled access paths, and for ramps, it would be a definite no-no!

Thanks for all comments. The path is for personal use, not very long, so I guess I'll replace the top with slabs.
