EVs causing potholes ?

You realize you're talking to his arse? (His head is deep in the sand)

[Chris Hogg]

Of course they won't. It's not in their interests to do otherwise. Their jobs depend in part on there being a climate emergency.

Around my way proper road resurfacing appears to be to remove the surface almost down to the underlying MOT and then replace with a single layer of thick tarmac. The half arsed way of resurfacing is to spray a layer of tar, sprinkle with some stone chips and maybe use a roller to bed them in. Wait a few days for vehicles to wear this new road surface back to the original (with a 10mph speed limit) and then come along with a mechanised road sweeper and collect 90% of the the new road chippings :(

A properly installed tarmac domestic driveways or public pavements may be two tarmac layers. MOT then a layer of tarmac with larger aggregate (smaller than the MOT) then a tarmac layer with smaller aggregate? When subject to loading they probably act as a single bonded entity rather than two separate layers. If they acted as two separate layers one could float on top of the other with water ingress.

Well no, because the department would have no reason to exist if they did.

Money trumps truth these days

I wonder if that was the original road surface? In many areas where concrete road slabs cracked up with heavy loads they bit the bullet and covered concrete roads with tarmac.

When "just stop oil" win there there will only be wooden wheels* on cars so we can go back to having road surfaces of 200+ years ago.

*Or maybe not if the "stop cutting down trees" green brigade win :)

At one time the road was the last thing to be be built on a housing estate. These days, by legislation, it is the first thing to be built.

I was thinking of the access roads to the site, not those on site.

[The Natural Philosopher]

An article on the M1 which was concrete said 'no one had built a road that cheaply before and no one ever would again'.

[The Natural Philosopher]

What a developer will do first is to lay down MOT Type 1 so the heavy plant and delivery trucks can get in and out and not bog down.

What a developer will do LAST is put the finished road and driveway surfaces down *once the heavy plant has finished*.

[Colin Bignell]

[Colin Bignell]

It still is. There is no wearing layer over the concrete and, apart from a little spalling, it is still in good condition.

I have seen a road where holes in the wearing layer revealed granite setts.

Its not the first thing to be built here. Now the first thing is the storm water pipes, followed by the sewer, because those are much bigger than anything else underground, then the water gas, electricity and fiber. Then the concrete curbing and then the road itself. Quite a bit of the time houses have started to be built before the road itself has been finished and a few have been completed before the final tarmac layer has been applied.

It makes no sense to do the roads before the underground services.

When they mill a road surface, 80% of the surface is recycled.

It is stored as aggregate-with-asphalt-coating, and is stored in piles out back of the asphalt plant.

We've been reducing the new petrol input to roads for a while.

When the material comes out of the crusher, it has to be checked for adequacy. Some loads won't be good enough for application to a road again.

This tells you that asphalt liquor can't be all that cheap, if they're going to that much trouble.

Or landfill charges and trucking charges for dumping commercial waste is not that cheap.

In some cases the cost of recycling is more expensive than creating from fresh raw materials and if there were not various legislation requiring recycling and additional taxes on dumping then perhaps certain recycling activities wouldn't happen.

[alan_m]

Asphalt containing coal tar could be considered to be hazardous waste for the purpose of landfill.

[Tim Lamb]

Road planings are available for purchase. Track/yard/driveway surfacing.

Lorry load or big bag.

I would think in nearly all cases, otherwise we'd have been doing it already.

There was always recycling of metals, particularly non-ferrous. When milk and soft drinks came in glass, the bottles were recycled. It's fairly safe to assume that anything that wasn't recycled wasn't economic to recycle.

The same with 'renewable' energy: if it really was cheaper, and fit for purpose, we'd have already been doing it. As indeed we were, on a small scale, here and there, when it made sense.

By the way, what happens when large-scale reductions of wind energy in some areas causes climate change? Who wins?

It's what you pay the devil with.
