My guess is their nemesis, the snowplow.
- gruez 9y agohow do normal speedbumps deal with snowplows?
- CydeWeys 9y ago"Raise Plow" road signs near the speed bump. This would work for non-Newtonian speed bumps as well, though the first time a plow driver doesn't see the sign, and there's always going to be one who doesn't see the sign, you end up wiping out the speed bump instead of just dinging it.
- taneq 9y agoMaybe you could have protective ridges at the side of the road which would act as hard stops for the plough while staying out of the regular path of traffic? I'd also be concerned about the effect that widely changing temperatures would have on the viscosity and hence critical speeds. It'd suck to install one in summer, get used to driving over it at 40km/h, then during the first cold snap find out it'd turned as hard as rock.
- will_hughes 9y agoIt's supposed to be like a rock at 40km/h anyway. You're supposed to slow down to 5-10km/h
- taneq 9y agoThe point was temperature dependence, not the specific made-up numbers.
- celticninja 9y agoThe difference though would be minimal at the recommended speeds which is why it probably is not a factor. If they were designed to keep speeds at 40mph then it probably would be.
- baldfat 9y agoWhat's the freezing point? Below the freezing point would be far from minimal?
- celticninja 9y agoDriving over it at 5 mph when it was frozen solid would probably be minimal.
- frankydp 9y agoUsually the thin small ones are removed in the season, and the asphalt ones have signs. This is the same reason the speed bands/rumble strips are concave not bumps. City plows also have shock absorbers systems that let them ride the bump, but you do get ice pockets after the obstacle.
- netsharc 9y agoit's a Spanish website, presumably an invention from a Spanish company. I wonder if a Norwegian customer said "What about snow?" and all the engineers thought "Oh...".
