Compaction to refusal

[KAMIKAZEE DIY]

Purely out of curiosity is to be expected/acceptable that a block paved driveway would show signs of tyre depressions after 25 years.

It's at my dad's house and he's not worried but it just got me thinking about the whole compaction to refusal theory I've read on here.

Too much time on my hands......

I think after 25 years any surface is going to show signs of age. Cracked concrete, mac degrading with loose aggregate and depressions etc.
If it's taken until 25 years to show any rutting I would say it's done very well.

How deep are the ruts. Lay a straight edge across and dip down with a measure.

The thing with block paving is that it can be reinstated by lifting and relaying the offending area. Realistically conc and mac cannot, certainly not without obvious patches.

My block paved driveway is now 21 years old and although the blocks are weathered to buggery and back, there's no ruts, depressions or hollows worth worrying over. A properly prepared sub-base should give at least 20 years of trouble free service beneath a typical residential driveweay. It's the surface layer (the paving) that usually lets it down - it weathers, it wears, it fades, it goes out of fashion - but the structure as a whole should remain serviceable.

I agree with Tony, I wouldn't want to see nor would I expect to see any of my jobs sinking after that time.
