 Drivers may notice more road buckles on concrete roads as the summer continues, but it's nothing to be afraid of if you're driving safely. Louisiana DOTD spokesperson Aaron Buchanan says road buckling is a normal thing that happens as debris and moisture fall into the joints of the concrete roads. Since concrete swells in heat, the roads can get pushed into a triangle shape at the joints. There's no real way on a day-to-day basis for our maintenance crews and their operations to really prevent this.
