This method of fixing potholes is the most retarded thing ever. They just fill the holes with concrete(or whatever they grey shit is) and gravel. It may fill the holes, but instead of being a hole, its now a bump. The filler wont last long either, so they have to fill it quite often. It would be much easier for the local government to get the shitty soviet age road dug up and replaced with actual asphalt. Not only would it look better and be smoother, it would last a lot longer, saving money in the long run.
