Failed chip seal

[slofox]

SH 23, from The Tron to Raglan, has recently been resealed in places. Some chip seal and some hotmix.

The hotmix is great. It's on the Western side of the hill section - it's 2km of tight twisty stuff and is really nice to ride now on the new hotmix.

The chip seal is mostly on the Eastern side of the hill. This is less steep and less tight but sweeps nicely and can be pretty fast if you are a loony (notmecoughcough!:innocent:). There are a few bits on other sections of the road as well.

The resealed chip seal bits have been down about a month. All the loose blue is gone and the road should be good to ride.

But this morning I noticed that large patches of the new chip have "fallen off". There are great bald patches in the so-called "repaired" sections. All within a month.

What's with this then? Did the contractor use flour and water paste to stick it down with? Seems like a crap job to me but then I know nothing about road sealing.

Some members on here have spoken with knowledge of sealing practices before. Anyone care to offer informed info?

Thanks.

Pfft! Try a straight section on SH2, south end of Dannevegas, 50kph zone. Resealed about 1 month ago. 30kph signs are still out and the entire length of it is shiny black no-chip in both wheel tracks in both directions.
We travel this way frequently, and in fact went through in one direction as the other side was being resealed...2 days later, as we returned, the chip was already gone in places.

Its usually water, wet road or wet chip that stops the tar sticking.

I have seen crews trying to put chip down after the tar has cooled and flashed off with the same result.

Call the local Transit engineer not the council and let him know his nice new SHW road has turned to shit. If he knows he might be able to stop the payment to the contracting company and get it fixed.

[unstuck]

As flip said, water probably the main culprit. Could also be dirty chips, Too much gritty shit on the stones and it will not stick. It,s not those Blacktop fellas doing it is it? They seem to be stuffing up a lot of sealing jobs around the country.:shifty:

You're wrong.
They didn't fall off in a month.
It took less than a WEEK.

And the useless cunts have done the same stretches about 10 times in the five years I've lived out here.

[Woodman]

You wanna read last nights letters to the editor in the Nelson Mail about dodgy resealing. Someone up here doesn't know what they are doing, its diabolical.

Hopefully the taxpayer doesn't have to pay to fix it. (TUI)

[Oscar]

...and while I'm in the mood for a rant - when the seal does become worn and shiny and fuckin' dangerous in the wet, what do they do?
They put up one of those slippery fucking road signs...cahnts.

[Damantis]

Just enjoy the smooth part while you can. Every summer, that peice of road melts and ripples up. Maybe we should all pay more tax and raise the required quality and standard work on our roads. It's all awarded by tender, and usually the cheapest wins. :no:

[\m/]

The new chipseal is fucking pathetic, most of the road they have resealed was better before the resealing. And Oscar is right, it fell apart in a few days.

[Smifffy]

Contractor wouldn't be EDI Downer by any chance? Those pricks have fucked up more roads around here than anyone else, including the logging trucks.

From what I remember while working in the roading industry, chip seal repairs (for Open Graded Porous Ashalt) came under TNZ P/11 which is a strict set of rules governing preparation, laying and monitoring afterwards.

Things do go wrong of course in some of the 6 stages however all work has to be signed off by a roading engineer and is guaranteed for 12 months. If the seal loss is greater than 10% the entire work must be redone unless it can be proved patching will be be sufficient.

Phone your council and complain because they have to address the problem.

[Flip]

P11 is a farking expensive open porous seal, its only used in Christchurch that I know. Its a specialist Fulton Hogan seal so I don't think Downers can get their hands on any.

Coarse chip is the cheapest and most often fucked up seal. The problem is they pay fuck all for road workers and they get monkeys.

If you find a bit of bad seal and its a hazard simply *555 and report it as a road hazard, the fucking contractors hate getting a call from the Rozza because they have to do some thing about it.

I had a tankslapper on that road that I will never ever ever forget.

P/11 is the specification for the process of laying chip seal not an open porous seal itself. Chip for roads (and all aggregates for that matter) must be of the approved standard under NZ Transport Agency (but still called TNZ) specifications.

I've made several complaints to a local authority responsible for the road in question. Problem was never fixed. In fact, I've had the roading engineer wallah effectively tell me to fuck off, I don't know what I'm talking about.

There is quite a bit of that happening in the King Country/Waitomo/Waikato regions...noticed alot of what you speak of yesterday coming back from the Naki.

[awa355]

While we're on about road surface's, I've noticed a lot of bends/corners in the Waikato/BoP, have been re laid with a brown chip. Runs from the entrance to the exit of most corners.

Is this a new type of seal? being trialled? . If it is an improved surface, re gripping, why not do the braking zones before the corners?.

[5150]

Has anyone ridden the new Pukete Bridge fourlane? Especially from The Base to the Bridge? Road just opened, and it is worse then a grovel road. All pack chip and already lines are marked. But you can see and feel cracks and holes. The road has only been opened for less then 2 weeks since new. WTF???

The guy that does this work is a customer of mine. He told me all about it.

It is a better grip surface and it is glued down with some fancy-arse bond. But I suspect the placement is designed to stop cars sliding into each other, not for bikes in braking zones. Oh and it's expensive too so the application is not that generous. How surprising.

That's not the top coat yet. They'll redo it once all the work is finished. Or so I am told...

[ducatilover]

Poor quality NZ roads? Oh surely ye jest... :bleh:

They'd better

You're right slofox, it is about stopping cars sliding although not into each other but sliding off the road. The "aggregate" is artificial and
has a higher PSV (Polished Stone Value) than natural aggregate and so retains its sharp edges longer after weathering etc. This gives a better skid resistance value.

As far as the Pukete road goes, the top coat will be applied after all the other work has been done, normal traffic volumes have settled the road in and engineers are sure there's not going to be a problem.

The got run over repeatedly and died. They are now ghost chip seal :confused:

Ahhhh! No wonder dey's gone den...

I think a lot of it comes back to money, NZ is not big enough economically to put the money into getting a good base for most of our roads. A few of the road workers that I know, know a piece of road is not going to be fixed properly because the base and surrounding drainage issues just will not get done, to a level where any surface will stay where you put it. The terrain and geology of this country have a big part to play also in my opinion, hard to build roads over old swamps and river beds that are moving all the time. I know I would be frustrated doing a job that is only a temporary fix, but the guys laying the stuff do not hold the purse strings and can only do what they are payed to do. I do acknowledge that there are some pretty slack sealing crews getting around though.:shifty:

I noticed that yesterday as well.

We were coming back from Whangamomona and the stretch from the turn off to Taumaranui/National Park through to Te Kuiti had some of the slipperiest surfaces I have come across

It got quite sphincter clenching on some of the bends with patches on them

[nosebleed]

I see what you did there. I think you're very witty, but Monique thinks you're dumb.

Just text "dung". Seems to be the only roading advisory initiative that has gained any credence.

[Bald Eagle]

least we can blame our shit roads when tourists throw their van s down the road

I come up to Hamilton about 4 times a year and each time I come up I think your roads are getting worse. When will your contractors learn to make a seal that stays longer than two weeks, joins to the previous road surface so it doesn't feel like a speed bump and doesn't bunch up when a truck goes over it.

I swear after the quakes we had some of your roadies down here, roads stopped being joined properly, pot holes started forming where new seal had just been put down and the roads were going shiny almost immediately after being put down. Thankfully it seems to have stopped.

[BOGAR]

There are quite a lot of factors that can cause the road to lose chip. Some have been mentioned and others are the temperature during the day or night. If it was too cold to seal which can happen on some shaded corners the road will fail. Some of the roads that looked great and then get a reseal (which then scabs) were done because they did not meet the new SCRIM intervention levels. Basically how much grip the road has in certain locations. Corners and areas of high stress breaking need more grip. The amount of cutter and if the bitumen has been modified to the local conditions are part of a formula that goes into the sealing information. It isn't always right or the factors on the day change too much for it to work successfully. By then however they are committed to sealing the road and they can only hope it holds. I'm not a sealing manager but I do look after all the data about the roads so I have been trying to teach myself about all the different factors of sealing. It is actually quite an art to getting it right.
Some more bad news for you though:
Funding has been cut by NZTA for up to the next 10 years and 1 of the possible changes may be lowering the speed limits on some roads to help them last longer or to build the roads to a lower level (less up front costs) to try and stretch the budget. This means they don't last as long but can be afforded now. There are a lot of projects that will not be done any time soon and only committed projects or ones of national significance will be built.
If we didn't allow the really bad cars with worn mismatched tyres ect we could stop wasting money trying to stop them crashing.

Thanks for noticing... could you keep them please?

Oh... and send yours here. Thanks.

Income insurance is what we used to call it.
Also means that you don't have to travel the country fixing roads.......when the one down from your house is repaired every 2 months.
Ever wonder why every town has a roading contractor?
But you didn't hear that from me :msn-wink:
