MOTO-NZ finally come up with something for all our money

[Ocean1]

I road over them this afternoon at 100kph and yes they do act a little like judder bars and I would imagine if you have a bike with firm sports suspension then you might get fractionally air born going over these.

Took the 1125 in for a new tyre this morning, made a mental note as I left to see what they felt like.

I was half way back up the Hutt motorway before I remembered. Can't have made much of an impression, eh?

LOL. Well it took me several weeks to notice they had even been done. It wasn't until I road them in the rain I though - hey I'm not moving sideways any more. Constant cars driving over them are flatting them out.

At speed in the wet I think that might cause a few unnecessary heart palpitations if you get momentarily, albeit fractionally, air born while in the middle of a corner.

How these behaved in the wet initially was in my view very dangerous and should never have been done like this. It created an unnecessarily dangerous situation for motorbikes. Careless in the extreme on behalf of the road owner. The current judder bar phenomena might reduce over time, but in the wet may still be hazardous, which is the point I think Bald Eagle is making.

I think what comes to mind here is 'suitable vehicles' for the road? If you buy a sprotbike with what is almost semi race suspension? Then dont expect it to absorb bumbs etc in the same way 'standard' suspension does. Sorry Mr. Kiwi, there may well be some issue with how the repair has been executed, but even my MT with Ohlins and modified front suspension doesnt seem have a problem with it either. Yes I know the sprotbike is the 'big seller' but it's suspension isnt really a road friendly set up.

It's a challenging area to apply to the road, but one we should examine to see if something practical (and useful) might come of it.

Here you are: theory and practise:

Thanks, yes have seen these links before in this thread...

Funny you mention it, but the truck that does the skid testing was parked in Mosgiel on Monday night.

Big yellow truck.

I passed the truck (I am almost sure it was the one in question) yesterday riding back from the Wairoa White Ribbon event to Napier at 5'ish pm. There was water spraying from the truck as it was doing it's work testing the roads. As the road yesterday was all day in direct sunlight there was quite a lot of soft tarseal and tar seeping up to the surface, I would be interested to find out what the readings were while going over the sun-affected bits of the road.

So would I. I lost my front end a couple of years ago around a tight corner hitting melting tar. Left hand blind corner with a steepish downhill gradient carrying normal speed for my adventure bike (just less than 30km/hr around the bend) when bang the front end went! Melting tar!

Can't find it, but I think it was in this thread(??) there was a comment re that issue having been solved in Oz. If that is correct, why have we not just copied what they are doing??

[caseye]

What'd they do over there then Con?

[Conquiztador]

Not sure. Only thing I got from the post was, that as Oz has hotter temperatures than we have here they have come up with a solution. But at the same time I would assume that we have that technology (or similar) here as I have never seen an airport melt under the sun? I do not know enuf about bitumen/tar seal/asphalt to know what is best and why.

Like you I don't know what was done over there. You are right about airport runways. Whats wrong with NZ Roads is simple. The tar seal guys are raping us! Our Emulsion contains upwards of 25% turpentine,simply, it's so fucking watered down that it melts at the drop of a hat.
I defy anyone who works in that industry to prove me wrong.
Fulton Hogan owns pretty much every tar sealing outfit in NZ, don't think I'm right? go take a look at who actually owns all the other names in road sealing, ultimately they all come under the Chinese owners of Fulton Hogan.
Roads made with the correct amount of everything, base metal, matting,lime where needed and of course either chip or hot mix are bloody near perfect.
Economics rules the making of our roads, not public safety, not an idealistic notion that our roads should be the best and safest in the world just money, it stinks.

I can't verify this but I had heard we cut our tar so that it remains more viscous so they can transport it further in trucks from the plant when making roads. The only problem being the tar permanently has a lower pour point (melting point) as a consequence.

So based on your comments, it seems that drivers/riders lives are exchanged for Chinese profit... and nobody is making any noise re this??

why would they? the Govt gets it's "cheapest tender" (or at-least biggest backhanders), the Chinese make profit & cut corners to improve this, & the general public is left ignorant.
Until it's cut enough to have a real effect on cars, no ones gonna investigate further

The first thing would then be to find a specialist on this subject of asphalt/tar seal who would be able to inform how it all works, and then to provide information re what is done in NZ, so that there would be some credibility to this. Any one have any idea where we could find such a expert who would be prepared to give this info?
