Is there any kind of legislation preventing new layer of road being laid upon new layer of road upon etc, etc to the point that there is hardly any depth of kerb left?

A local, residential 30mph through route has once again been resurfaced.
There are well used pedestrian paths with dropped kerbs along each side of the 2 mile stretch.

With the last lot of re-surfacing the road surface was brought above the dropped kerb level - requiring the surface to be continued a little way up the run ups/pavements to prevent large puddles and manholes/drains/iron works have been raised over the years.

It's just been re-surfaced again. Obviously they had to go further up the run-ups/pavements again.
This isn't however my main concern.

I always thought that kerbs were in place to deter vehicles from mounting the kerb in order to protect pedestrians.
The difference in height between the road and (fully) kerbed pavement height is now less than 25mm in most places and at best only 50mm

So back to the original question:
Is there any kind of legislation preventing new layer of road being laid upon new layer of road, upon .. etc, etc to the point that there is hardly any depth of kerb left?

I wish.

They built my road 8 years ago, with kerb stones to mark where the pavement should be, but no difference in height between pavement and road.

The objection raised by residents was exactly the same as yours - the kerb is designed to help prevent cars straying onto the pavement - and with no height difference, cars not only park on the pavement, I've also seen them cut the corner outside my house, driving on the pavement too.

...but nobody is going to do anything about it.

Yes I've seen on new build estates - not so bad when the road is narrow, twisty and the average speed is probably lower than 10mph.

The road in question is at least 70 years old, 2 miles long and more or less straight. Although it's 30mph I would guess most traffic travels between 40 and 50 (I remember my brothers and mates in their boy racing years trying to reach 80 along it!). So to have such little kerb height just seems wrong when the pavements are also a well used pedestrian route.

See you're in Essex - they've been doing this in Chelmsford a lot lately. Terrible job of the resurfacing.

It's Chignal Road I'm talking about.

Most Local Authorities Highways Departments will publish their own design guides for residential and commercial estate roads. This will provide guidance on the required kerb face height in different locations.

Some residential streets are designed to be 'shared' so the kerb is less (or non-existent) than where the highway is designed to be separate from the footpath for example, so there is no specific 'one size fits all' height.

If you are concerned, check with the LA's highways department and ask for a copy of their design guide (usually available as a free down-load) so you can see what would be expected regarding kerb heights in that location and that could form the basis of a challenge. However if there's no direct safety issue I wouldn't expect a positive outcome given councils budget restraints.

Cheers .... that's the kind of info I was after.
