Road crossing damaged by rubbish trucks _ WWYD?

Michele Neighbourly Lead from Onerahi

We live at the end of Raumati Crescent, Onerahi. Our street doesn't have a turning circle, it dead-ends at a tin gate that leads into Dragonfly Springs.
Over the last 5 years our road crossing has been damaged by trucks using our driveway, and our neighbours across the road, as a turning area.
I have contacted the council as it is getting to the point where we need to repair it. I don't want to spend money on it, to have the following week trucks drive on it and start destroying it again.
I spoke to someone at the WDC, and was told that the trucks are not allowed to drive up on driveways or over the kerb. Also, even though road crossings are on council land, the landowner using it is responsible for maintenance. This I already knew.
I only started driving again about 6 months ago. I knew the crossing was damaged but not how badly. Water is now starting to undermine it even more, and the trucks still nudge the edge with their tyres as they try to turn, causing it to break more.
If you break it you pay for it. Council won't even consider repairing the damage their contractors have done, the buck was passed from Roading to Waste, who said "we will remind the drivers to not use driveways". Attached are two photos. First one is from Google Streetview from 2012. You can see the damage starting. Driveway has been there since 1984. It was in perfect condition when I moved here in 1995. In the last 5 years we have had 3 heavy rubbish trucks every week. It has been destroyed.
Second photo is from today, April 2017.
I have talked to someone about putting a steel plate across the entrance, but really why should I pay for something I didn't break?
Sorry for the long winded rant. Just wondering what would you do?
Would you pester the council?
Would you talk to your local councillor?
Would you just repair it, hoping the trucks stop using it?
Would you leave it?
Or would you put in a steel plate and still hope the trucks quit using your driveway?
Looking forward to your comments ☺

UPDATE: 11/05/17. Have had a visit from council and Northwaste reps this week to look at damage. Lots of talk talk. Now waiting to see what happens.
