Speed Bumps And Speed Humps

There is a dramatic difference between “speed bumps” and “speed humps” but many people mistakenly use the terms interchangeably.

The simple difference between the two can basically be measured by the traffic calming affect of each device.

Speed bumps were designed to slow traffic from 0 to 15 mph.   Whereas speed humps slow traffic from 10 to 20 mph.

The way they fulfill their particular purpose is based on the cross section or the profile and the transition between the roadway surface and the device itself.

The speed bump profile is a more abrupt profile.  There is little distance between the roadway surface and the full height of the speed bump.  It can be compared to running over an object like a two by four rock in the middle of your tire.  This abruptness causes traffic to slow down to almost a stop before crossing over it.

On the other hand the transition between the Speed humps profile and the roadway surface is tapered and makes for a less abrupt transition between roadway surface and speed hump.   This is similar to running over a two by ten board with tapered edges. It causes you to slow down but not necessarily to stop.

Installing Rubber Speed Bumps on Asphalt surfaces is literally as easy as 1-2-3.

And it does not require any special machinery or equipment either.

The only equipment you’ll need to install rubber speed bumps on asphalt surfaces are:

1. Mallet

2.  1/2 inch diameter x 14 inch long rebar spikes

3.  Hammer Drill with 1/2 inch diameter drill bit.

4. Broom

5. Rubber Speed Bump

Once you’ve assembled all the tools and equipment, installing speed bumps is very simple and can be done by one person in less than 10 minutes .

Step 1 - Position the rubber speed bump in the location you desire.

Step 2 - With at least one foot on the rubber speed bump at all times,  to keep the speed bump from moving,  use the hammer drill to drill a 1/2 inch diameter hole, 3 to 4 inches in depth, in each of the speed bumps recessed installation holes.

Step 3 - Remove the Speed Bump from the desired location after pre-drilling all holes.

Step 4 - Redrill each hole if necessary and sweep clean the asphalt surface before resetting the speed bump.

Step 5 - Use the mallet to pound the 1/2 inch diameter rebar spikes down into the recessed pocket provided on the speed bump.  Always keep weight on the speed bump while pounding to ensure the bump does not move prior to completion.

That’s it.  That’s all there is too installing a rubber speed bump!
