Lidl report

So a trip to Lidl about 7pm where my mother picked up 6 bottles of white and 4 small bottles of white and 15 associated bars of chocolate, which she got a £5 off with some coupon from the Express. She's running a tombola or as Word insisted a Tom Bola when my father made up the notices "But it didn't like it and suggested that" as I'm sure you're aware tombola isn't split or hypenated as it comes from the same source as tumble it's not derived from Tom's Bola or whatever.

Anyway mum wasn't as agitated as normal, perhaps because to distract her we played the tha-dump game on the way (and on the way back too); like the best games it's simple in theory but requires finesse to perfect.

Essentially it's an attempt to predict potholes, bumps, dips etc. i.e. when the car goes tha-dump. The person who calls tha-dump closest to when the car goes tha-dump gets that point. Obviously works better on oft-travelled roads, and while shotgun gets an advantage it still varies depending on the speed and sometimes placement of a car.

Playing this reminded me of the depression in York Street that I discovered on Monday - where the hell did that come from? It's as if a section of the ground underneath the road has just disappeared; it's a true dimple rather than a crack or tear as if the road has been sucked down at that point. It's quite deep too, at least feels that way if you run over it and of course it's right at a point you're likely to run over it. How long has it been since they resurfaced it? Not that long.

When you get that kind of depression, it's because the surface tarmac is fine, but the bedding has been damaged. I think it's usually caused by HGVs - the vibration and weight penetrate the surface and break up the bedding. Simply resurfacing doesn't prevent or repair it - you need to dig the whole lot right down to the soil and re-lay the road from scratch.

Yeah that fits with observation, the tarmac is unbroken, it's as if someone's just pushed a finger into cellophane. So betting is now open - will they just dig it out as a square and fill it in, or just stamp some tar over the top of it?

If Cambridgeshire is anything to go by, they will first add a patch on top of the existing surface, which will come off within a month, probably taking some of the existing surface with it to make a pothole. Six months later they will notice the pothole and fix it by cutting a square out of the surface and filling it in. That might last for three or four months before it sinks again, after which they'll probably do the same thing a few more times. Eventually they'll notice and do the whole stretch of road.

Cynical, me? Nah, I just go on experience.
