Where barriers have been damaged, temporary barriers made from the robot can be installed. In theory, the entire section of the barrier that has been damaged could be replaced by a fractal machine as the functionality of the machines increase. Wet Road Repair Under severe wet weather conditions, road repairs can become somewhat a pointless exercise using conventional machines. However since a fractal robot shields the road surface while repairs are going on underneath, the weather is not such a big issue. Where water is likely to enter the road surface through leaks in the drainage system or flooding due to fords or other local features of the road, the machine can tile barriers to steer the bulk of the water away from the road.
Pumps placed strategically can remove the remainder.
Plants Plants continually sprout from areas of the road where rubbish has built up, or in areas where there is a lack of frequent use. Defoliants are used everywhere but they don't necessarily work all the time in every square inch of the road. Also in spring time, plants blossom and grow, infringing into the road space. Such growths have to be trimmed immediately to keep the roads clear. In forested areas, trees start to grow branches that can be hit by passing lorries - especially in severe wind conditions where the branches bend a great deal more than they otherwise might.
