improper substrate prep before paving, lack of proper drainage...etc.
My pet peeve is the fact that often times, when they repair a road by laying a new layer of asphalt, they don't actually scrape the previous layers off but rather just pour the new asphalt on top of the old one. Result is that the surface of the road is on a higher and higher level and on intersections or going from the road to the sidewalk, there's a huge drop. One such case was in POP in the intersection of Manolo Tavarez Justo at the entrance of Torre Alta. Normal cars with a regular ground clearance would need to carefully maneuver through that, otherwise they would be left wheels hanging in the air... Pure incompetence...
On the road that passed our house, you could actually see the various layers, there were 4-5 of those, going from newest on the top to the most faded one in the bottom from years and years ago... This is another reason why I personally would never want a sedan in the DR, only SUV with proper ground clearance...
