Travertine pavers driveway in cold climate
Can travertine pavers with 1-1/4" thickness be used for driveway in cold climate? The driveway also has a high slope with a rise of 7' over 120' length. Here are my thoughts:
1. Base: 8" compacted gravel and 1" sand. Should deeper base be used?
2. Choice of Travertine Pavers: Brick, cobblestone, granite pavers are no brainer, as they have been used for centuries. I am trying to explore travertine pavers for driveway in cold climate. The travertine pavers seem to be quite strong for the cold climate, but these pavers tend to have small holes, which may break the pavers through the freeze-thaw cycle. Should travertine pavers be considered for this project?
3. Size of Pavers: 6" X 12" with 1-1/4" thickness. This size should withstand the pressure of cars without breaking. Is this size OK?
4. Pavers Type, Tumbled or Chiseled: I am not sure on this. The tumbled pavers seem to be less slippery on the surface, so they will be better in snow and rain. The Chiseled pavers have better traction on the edge, but they are more polished on the surface, so they will be more slippery and will have less traction on the surface. Travertine Mart suggests chiseled pavers for driveway, but I am not sure if their recommendation includes driveways in cold climate. I am also concerned about the high slope. Which type of pavers should be used?
5. Paver Sealers: The tumbled pavers may require sealer so as not to get too dirty over time, but that may make them too slippery. Once again, there is additional concern for the high slope, especially during snow and rain. The sealer should also provide some protection from water, and may prevent or reduce breakage from freeze-thaw cycle. Should sealers be used for the tumbled pavers and/or for the chiseled pavers? What kind of sealers (also which brand) would be the most appropriate?
6. Polymeric sand: I do not think the polymeric sand will add any benefit, as the pavers fit quite tightly. In addition, the water may seep into the ground through the space between the pavers (this may be good and bad). Should polymeric sand be used?
I have lots of questions, but I want to make sure if this project can be done with travertine. I have not heard of any travertine driveway in cold climate. I will appreciate comments from the travertine pros with experience in cold climates. Thanks.
