Standard detail size for a highway kerb cut? - Highway kerbs

[Rawfella]

I'm looking to find a Standard detail size for a highway kerb/edging cut.

I'm confident it is no less than half or 450mm should be accepted but cannot find any British standard detail on this. Can anyone help?

I have only ever gone 450, anything more looks shite and i don't think could take impact.

[Rawfella]

Thanks that my understanding too, but can't find a standard detail

[seanandruby]

I think as long as they are not overly to small they are ok. If you have to cut then try and even it out by cutting two kerbs. I've seen guys do a 200 cut and it looks shite. It's just laziness really, so they just do one cut.

I thought the min was 300mm

[Rawfella]

It's a bit of a tricky one I think it's down to engineers discretion because I can't find a British standard on it 😕

I think it's 600mm.

Apologies, it's a half kerb, 450mm........duh

It's covered in SHW ... somwhere. 1100 series? Minimum kerb cut size = half a full kerb, which gets confsuting because some kerbs are much less than 900/915 mm

[seanandruby]

... I thought that. But what throws me is the corner units are 300ml, would of thought if 450 minimum then surely that's what size corner kerbs, cheeses etc; should be :;):

That's where I thought I'd find it in 1100 but nope not there 🤔

Not sure if this is much help anymore, its pretty much been answered! Have a standard detail I use that might be of use?

See note 7 - link below.

BS 7533:6 - 4.1 "Units conforming to BS 7263-1 (now superceded but it means road kerbs) should not be cut to lengths of less than 300mm"
