Ha, I assume you meant agree since that was exactly my point.
Loads of roads around here full of potholes, uneven with road base collapsing, edges crumbling away and it just gets sprayed with surface dressing over the lot. By next winter it’s back to being worse than ever.
What i meant was, surface dressing is an excellent way of maintaining the integrity of the road surface, unfortunately due to lack of funding, by the time roads are dressed they are no longer structurally sound, hence my analogy with wooden window frames, doesn’t matter how much surface treatment is applied once the structure is shot, it isn’t of much use.
I appreciate no one likes surface dressing but done correctly at the right time the cost is more that 10x less per m2 than planing off and resurfacing with fresh asphalt and can then extend the life of a road by 10 years or more.
