$this->bbcode_second_pass_quote('Russian_Cowboy', 'I') wonder why one can't build roads out of steel mesh. Same thing as sections of certain bridges that are not susceptible to icing that i have seen in the US, especially in New England, and Canada. This will make road construction about seven times more expensive per mile, but the roads will be virtually maintenance-free, ice-free, and oil-free. There is lots more iron ore underground than there is oil needed for asphalt. The only thing is it will have to be protected from looting plus the car tires will be worn out much quicker.
I can't see the grip being very good in all honesty, especially during rain. There's a motorway in the north of England, the M6, which runs up through the mountains. I've come off onto the slip road in heavy rain and at the top of this junction there's a metal cattle grid. As you go onto it when braking, the wheels have a tendency to loose grip and lock.
Steel grids won't last very long with trucks. You would need a lot of steel as well.
Of course the other alternative material is concrete, usually in slab form. It tends to be a lot more noisy though and probably more expensive.
