We've been on the road for seven weeks now and have travelled about 8000kms. In that time we've been up through
Flinders Ranges,
Oodnadatta Track, Uluru, Tennant Ck, Mt Isa etc and have only had one stone hit the windscreen - no damage.
This morning on a good bitumen road north of
Cobar a small road train went past and we got a spray of rocks - there would have been at least a dozen hits on the windscreen/bonnet. It was like someone had got a handfull and threw them at us. Looking at the road there appeared to be no reason for what happened. And now the windscreen has got a chip in it.
So where did the rocks come from?
regards
John

caught up in the chassis etc under the road train and as they rattle along they vibrate out and drop to the road at 100km/h and skip merrily toward the oncoming car. Fun aint it.

howesy hit the nail on the head I would say... but
Another way is that the top layer of stone is beginning to dislodge from the seal. If this was the case the road is in urgent need of a reseal.
Or when the road was sealed they did not broom it off correctly and some loose stone is still around.
Then was the road train carting a load of gravel uncovered?
There are some options for you....not sure how it will help :-)
Cheers Tony

We've all gotta make a buck, can't forget about the windscreens installers!

We have just got back from a 10000 klm trip and have 5 chips in our windscreen, I think most if not all of those come off of the butumen. I think when you meet a car on a gravel road every one seems to slow down therefore avoiding the problem.

Could also happen if the left rear trailer tyres drop off the bitumen, had that happen even on straight road

G`day John,
The Road-Train wasn`t loaded with gravel ( rocks ) was it ??
You could possibly convert your windscreen to frosted glass by following a sand truck for a while.
Just a thought,
Scrubby.

Alloy c/t
For your info the bloke in front was with me & I took off after the b-stard,(broken windscreen) so I know. I drive Semi's / B Double's & have a good sense of speed which obviously you don't. You are probably one of the dumbells that do the same, but judging by your answer I doubt if you could handle a lawmower little alone a vehicle. Don't work for the Council do you ?

Actually Alloy you are assuming lots as
well.
I will assume, juging from your reply, that you are perhaps lazy, working for council too, not being able to read the speedo to determine your speed, not having the IQ to guess the speed of another vehicle travelling the same speed as you, and sadly I am assuming you don't know what knock-off time is

The road train was carrying large pipes on both trailers. We had passed quite a few of them on the road north of
Cobar and had no problems until this one.
I could understand one or
two rocks getting flicked up, but this was like a machine gun going off. Maybe it was just bad luck.

John

With the amount of rain around
Cobar and the road damage it has caused you may find that the RTA have sent the tarpatchers out whilst it is still wet and sprayed a fine coated gravel into the holes.
Sticks better to tyres than the road.
I travel in these areas and my car is covered in fine tar which when you run your hands over the paintwork it feels like sandpaper.
Lucky I have a black car.

Hi
Heard an interesting comment recently.
It is not the speed of the flying stones that causes the damage, but the speed of the vehicle that hits them!!.
As a suggestion slow down and get out of the way of approaching road trains. After all it is the oncoming vehicle that is most likely to receive the most damage.
common sense should apply again
I have met/ seen a lot of pipes being carried out there on the last trip, must be a major gas/oil reticulation coming on line somewhere.
Cheers
Russ

Russ- Put that down to an old wife's tail :-)
I have parked
well off the road when I see road trains coming in WA. So here I am not moving
well off the side of the road. Result smashed windscreen.
So I was doing zero rock much the same speed of the passing truck. It has happened twice to me.
Now what you will find it would be a combination of
the rock speed/size and vehicle speed with factors like trajectory angle that would all combine to result in the windscreen damage.

the rocks came from the road-train looking in his right-hand side-view mirror rather than his left-hand side-view mirror...
have you noticed how a oncoming double sometimes "flicks" it tail in and out as it makes it way towards you?
Driver does this so when the rear trailer is flicked onto the the fogline he has a nice full uninterupted view backwards from his right-hand side mirror.

Hi there, cant help you with where the rocks came from but we had a similar experience on the Golden Hwy. a couple of months ago which resulted in a chip ("star") in our windscreen.
O'Brien's Glass quoted $130 to fix the chip whilst Koala glass quoted a similar figure to do a repair job but advised us that they could whack a new screen in for $210 and suggested that at this point we do nothing as they said it was a 50/50 chance that the "star" would not progress further & that whilst it was our choice we just wait & see what transpired. So far so good, so we are still "waiting & seeing" LOL So hope that is of some help to you. Good Luck
