Why drive to the northwestern corner of South Carolina? Freightliner, owned by Daimler, built our 2004 Winnebago motorhome chassis. The Techs at the Factory Service Center are trained and certified in chassis service. The maintenance checklist is very thorough and the service is excellent.
Our drive starts on Interstate 85 North toward Greenville, South Carolina.
Another day, another Road Construction Zone
He tells me about their function in Concrete Road Construction while I take more pictures of the "Cages."
Dowel Bars or "Concrete Cages" are placed before concrete is poured to make a new road. When two concrete slabs are next to each other, half of the cage is covered by one concrete slab. The other half of the cage is covered by the neighboring slab. The hidden rebar "Cages" keep the concrete road's slabs from moving up and down when a car or truck drives on the road.
Building a concrete road has many steps. Concrete roads have cracks between the slabs that are sealed with some sort of caulking to keep water and road salt from breaking down the concrete and the rebar "Cages."
When you drive on a concrete road and your car is going ka-thunk, ka-thunk as you cross the concrete slabs, the "Concrete Cages" that anchor the joints between the slabs are moving up and down. This happens when a concrete road ages and the slab joints have not been resealed regularly. (Thank you, Eric, for writing this for me.)
