Interesting point

[Jaws]

If there is enough time, money and tarmac for hundreds of speed bumps, why is there no time, money or tarmac to repair potholes properly ?

 

[pappajohn]

Because all the time, money and tarmac was used filling 'negative' potholes... AKA... speed bumbs.

 

[DBK]

It's down to the Conservation of Mass law. Each speed bump installed creates a corresponding pothole somewhere else.

 

[pappajohn]

Why do Australia's outback dirt roads always have corrugations going across the road and never along it.

 

[TheBig1]

I can't find it right now, but there is a demo video of a pothole repairing machine on a lorry. 2 man crew and it takes 5or 6 minutes to complete

pull up
suction pipe empties the hole
flame jet heats, dries and melts the bottom and sides of the hole
a chute deposits the tarmac and stone
a foot is swung out and compresses the new tarmac
pothole filled and sealed

onto the next one

if each county invested in buying or leasing one, then the issue could be quickly and reasonably cheaply solved

There was a gang of blokes fixing potholes in the road outside my house a couple of weeks ago - at midnight!!

In which alternate reality?
A machine like that would need to run continuously with a rotating crew on shift to fill ALL the potholes in any but the most underpopulated counties.
6 mins per hole plus travelling and positioning time to the next hole.... 4 or 5 an hour at best.

we are not talking country lanes here in the first instance, more like a town road per day at worst. more likely it will be 3 or 4 roads in an 8 hour shift

All toads do it.No idea why ? we used to use one in essex that was exactly the same . the Rambla's in spain corrugate the same direction also.

A bit like ying and yang then.

Sounds about right.... 4 or 5 holes an hour... 3 or 4 roads a shift.
But here they won't close bus routes for one thing unless it's burst mains etc and the council post parking prohibition notices up to a month previous for maintenance work and are, on the whole, ignored on the day.
Yes, the cars get a ticket...... But the cars still there with its ticket on preventing the work continuing.
Manually filling is quicker but the council don't have money for it.

Forget cars, let's all buy a tractor and bugger the road condition.

Those in the know say its wheel bounce.
Once it starts bouncing it lands and starts another ridge and consecutive wheel bounce continues it.
Can't see it myself..... A car wheel is going to bounce different to a 600hp truck wheel and every bounce of every wheel will land in a different place and the gravel displaced will be thrown back into the ruts behind filling them. yet these ruts are uniform and straight across in one line.

I watched pothole fillers outside our house. Lorry pulled up, man shovelled tarmac off back, into hole then whacked with shovel. That was job done!!

Turning a pothole into a pothump and then hoping the cars will squish it flat with the rest of the road.
Pathetic really isn't it!

They did that locally.. Old lady tripped over the ( quite big ) lump they left and broke her wrist..
The resulting costs of the court case was enough to lay a whole new road.
Rest assured they do not use that method around here any more

Ain’t life like one big pot hole

I came across an unusual "reverse speed-bump" in France recently. It was a concrete depression or trough across the road, that is it didn't stick up but was below the road surface either side.

It was very effective because you really had to slow right down. The 10kph limit was about right

They were probably stealing the tarmac ? ?

 

[Flook]

I was under the understanding that the speed bumps were over filled pot holes. . . Mmmm.

I wonder who came up with the clever idea of the smaller speed bumps.

You know the ones where you can straddle it with the car and not slow down ?

 

[Sheddy]

The murram / dirt roads in Kenya always corrugated as you were approaching a bridge or culvert, and were different on both sides of the road, so we always attributed it to the braking areas. They caused absolute havok with our mobile Radar systems causing no end of damage shearing plate steel and aluminium box sections for fun.

If laid down correctly a car should still hit it but wide track emergency service vehicles should clear, well that was the theory. Also means white van man can still go flat out.

That doesn't explain the triple hump.... One in each lane and one the same size just after (or before depending on direction) straddling the white line and overlapping, width wise, the other two.

Effects of suspension over time I believe

Sooooo pointless then ?

 

[mitzimad]

logic tells me if they left the pot holes they dont need speed bumps so win win
