Is there any plausible reason such arrows would be broken up on purpose? In my mind, I would want more things like this to exist; large physical failsafe markers seem like a great idea.
- Sanddancer 13y agoThese arrows, probably not so much, as they are pretty much all in the middle of nowhere. However, general concrete recycling is useful because breaking up existing, unused concrete for works projects tends to be cheaper than, and is more environmentally friendly than, quarrying.
- HCIdivision17 13y agoAh, I did not know that. Thanks!
- javert 13y agoI don't get it. Doesn't concrete crack and break in a messy way? How could it be re-used?
- 286c8cb04bda 13y ago> How could it be re-used? To somewhat over-simplify, concrete is made from three things: Cement, large aggregate (big rocks), and small aggregate (little rocks). Broken up concrete works pretty well as large aggregate.
- javert 13y agoAwesome, thanks!
