recycle spanish roof tiles for drive/walkway
i have an opportunity to obtain a large number of used "s" shaped spanish roof tiles for free! hence i write my question here.
my idea is to bury them all lined up so that only the "s" shape is visible next to my driveway paths which are made of turfstone- concrete pavers with grass in the holes.
right now i have pea gravel as a walkway beside the driveway paths and those little stones go all over the place.
my concern is would the tiles be able to withstand the weight of a car should a wheel go over the pathway.
the tiles seem to be about 10 inches long and 6 or so wide and so would be buried nearly the whole 10 inches deep. i can't seem to find any information to determind either yes or no.
would an thin layer of morter or cement help provide strength?
what do you think my frugal gardeners?
