Speed bumps are permitted on public roads, unlike the trapezoidal type, and speed bump type speed bumps designed by some manufacturers. It is prohibited to install speed humps on roads. At least 6,000 vehicles are required to travel daily on roads with a steep gradient and at the entrance to built-up areas. Its implementation is, therefore, limited:
- to agglomerations
- parking areas
- subdivisions outside built-up areas
- on the roads of road and motorway service and rest areas
The speed cushion is imposed in particular in zones 30; these are zones where the speed of circulation is limited to 30 km/h because of the possible dangers that road traffic could cause for pedestrians and cyclists passing through the zone. Some places, in particular, require the installation of speed humps: schools, hospitals, entrances to city centers, and commercial areas.
If a slowing device is needed on private roads, speed bumps Tucson for example offers five models of speed bumps and trapezoidal-type speed bumps that will meet the specific needs of the layout.
The speed bump type speed bump materializes an elevation of the roadway in a rectangular shape. Unlike trapezoidal-type and speed bump-type speed bumps, the speed hump does not span the entire roadway width. Its location does not therefore constitute a hindrance to the passage of public transport vehicles, heavy goods vehicles and two-wheelers: the raising effect is attenuated.
Like all other speed bumps, the speed bump is made from 90% recycled and 10% pure rubber. This rubber is strong while being flexible: these characteristics are obtained thanks to the rubber’s vulcanization process. The quality of the material used to make these speed cushions justifies the latter’s price. The unit price of speed humps may decrease if ordered in large quantities.
To ensure the safe passage of vehicles, the speed hump has a textured, sanded surface with non-slip properties to prevent slipping. The coefficient of friction measured is more significant than 0.65, knowing that the standard requires a coefficient of friction for a road surface of at least 0.45.
In terms of packaging, all speed bumps are packed piece by piece and are stored in custom-made crates for maximum protection during transport. Once the product has been duly received, the customer only has to install it: it is quick and easy thanks to an integrated fastening system.
