"Double the life" is unrealistically pessimistic.
A cul-de-sac gets far, far less than double the traffic of a normal road, and vastly less traffic in the form of heavy vehicles. Road damage is proportional to the 4th power of axle load (according to the US GAO).
- Arnt 6y agoDon't you have weather-induced damage there? Potholes that appear when the weather thaws in spring, or when rain and sun take turns wiggling the materials?
- hguant 6y agoSure, but you need cracks and fissures for water to freeze and thaw into, and without heavy trucks compressing, stressing, and wearing away the road surface, those cracks take much much longer to develop.
- Arnt 6y agoI think that means "no, we don't really have that", because where I'm familiar with roads, the seasons and weather will do that quite unaided.
- dragonwriter 6y ago> Don’t you have weather-induced damage there? Weather-induced (largely water-induced) damage is driven largely by access to water provided by surface damage, which is driven by road weight and traffic volume similar to deeper damage, but also by traffic speed and resulting tire hydraulic action more than deeper damage is. Low-speed, low-traffic-volume roads than generally see personal passenger vehicles and smaller delivery vehicles without many heavy trucks will also see a lot less weather damage.

- timw4mail 6y agoI have never seen sidewalks replaced as a maintenence task.
- boomboomsubban 6y agoEven assuming none of them get replaced ever, it takes around a century for the current taxes to pay for what it cost. Skewing the replacement costs isn't changing the argument.
