Speed Humps

What are Speed Humps?

The purpose of installing speed humps on roads, driveways and in car parks is to physically force vehicles to slow down to a safe speed. At a reduced speed, vehicles can stop more quickly within a shorter distance to protect pedestrians from injury or death.

There are many different types of speed bumps which are all designed to suit different situations. Regarding weight capacity, all fixed Area Safe Speed Humps can easily exceed more than 20 tonne pressure, but this is only part of the performance story. Correct installation method also contributes to the long term durability of a speed hump.

Clean & green – the use of recycled materials and an understanding of Australian Standards (AS2890.1-2004), make Area Safe speed humps the best choice you can make.

Speed Hump Positioning

• The best position of your speed hump is subject to the particular needs of your site
• It is recommended to position a speed hump approximately 1-2m from a danger point such as pedestrian crossings, security gate house, toll point, boom gate, cross over
• The recommended spacing on a long driveway is no more than 10-20m apart otherwise vehicles can build up speed between them
• Leave approximately 3m between a speed hump and the edge of a side road/driveway to avoid vehicles turning their wheel on the speed hump which puts undue pressure on the fasteners
• Consider leaving a small gap for drainage between the end of the speed hump and the curb (if adjacent to a curbed shoulder)
• Consider leaving space at the end of the speed hump if the edge of the roadway is also to be used by bikes, pedestrians, wheelchairs etc
• Minimize the gap at the end of the speed hump as a large gap can be tempting for vehicles to swerve around the speed hump. When this happens the risk of collision with pedestrians or property increases dramatically

Recommended Installation of Rubber Speed Hump onto Bitumen

• Clean area
• Position speed hump or template according to the site requirements and customers own risk analysis (see above). A laser, string line or chalk line can assist with accurate alignment
• Drill Ø12mm pilot holes through the fixing holes in the speed hump (or template) just penetrating through the bitumen layer
• Move speed hump or template aside and test that the plastic plugs will insert firmly. Enlarge hole slightly if the plug will not go in – try Ø14mm drill bit (TAKE CARE: if the plugs end up loose, the fasteners will not hold)
• Clean the area and apply sealant adhesive to each hole, bearing in mind the number of plugs that can be fitted before the sealant dries
• Gently hammer in M14 x 75mm nylon plugs until flush with surface
• Add sealant adhesive to underside of speed hump (optional)*
• Position the speed hump accurately and fasten with washers and M12 x 75mm coach screws into the nylon plugs. To avoid a tripping hazard, ensure that the top of the fastener is seated correctly in the recessed area below the top of the speed hump

Recommended Installation of Rubber Speed Hump onto Concrete

• Clean area
• Position speed hump or template according to the site requirements and customers own risk analysis (see above). A laser, string line or chalk line can assist with accurate alignment
• Drill pilot holes Ø12mm x ±10mm deep through the fixing holes in the speed hump (or template)
• Move speed hump or template aside and finish drilling holes Ø12mm x ±70mm deep
• Extract dust from holes and clean area
• Add sealant adhesive to underside of speed hump (optional)*
• Position speed hump accurately and fasten with washers and M12 x 65mm flush-head D-Bolts. To avoid a tripping hazard, ensure that the top of the fastener is seated correctly in the recessed area below the top of the speed hump

*HANDY TIP!*

Flexible sealant adhesive also used on the underside of the speed hump helps to reduce forward / backward pressure and therefore reduces the stress on the rubber around the fasteners

Please note - It is the customer’s responsibility to ensure that the product is suitable for the application and that it is installed in a safe manner based on customers risk analysis.
