Dirt Road Speed Bumps

Product Description

Our Dirt Road Speed Bumps are an effective solution to the thorny problem of traffic calming on a dirt road. Traditional methods of anchoring speed bumps to traditional paved roads work poorly on dirt roads. But the RubberForm team worked with industry experts to carefully innovate an earth anchor screw system that makes our Dirt Road Speed Bumps as reliable as our paved road model.

They’re also just as easy to install, easy to relocate, and highly visible day or night. Our speed bump’s 100% American recycled rubber won’t crack, crumble, or corrode, no matter the heat, cold, rain, ice, or snow you throw at it.

Product Description

Dirt roads are a traffic calming nightmare. They’re unreliable, unpredictable, and have a huge range of surface variability. Our Dirt Road Speed Bumps solve all these problems.

They’re simple to install (even with the specialized earth anchor or our galvanized spike system) and just as easy to remove or relocate later. Which you probably will, given the unpredictability of dirt roads. They’re fully modular, dove-tail connection design, which means you can link them together to span any width needed. Their reflectors and safety reflective strips maintain high visibility at night, in fog, rain, or snow. They also come in two heights, 2.5” and 3” high which means you can slow your target traffic down to as little as 3-5 miles per hour, or select a height designed to slow larger work vehicles instead of personal vehicle traffic.

Our speed bumps are carefully innovated to withstand every possible environment you might want to install them in. They won’t melt in the searing summer sun or shatter in the frigid cold. They’re unaffected by rain, ice, or snow.  Our 100% American masticated recycled rubber won’t chip, warp, or spall either.

How are your speed bumps and speed humps anchored down?

We offer a lag bolt mounting system consisting of a lag bolt, anchor, and washer to anchor into pavement or concrete. There are 4 anchor holes for our MLSB product line in each speed bump. For temporary situations, you can just lay them down or moor them in place with our GRK’s RSS™ Rugged Structural Screw. For our RK Series speed bump and speed humps, there are 2 anchor holes for each 24” long section.

Can your speed bumps and humps be installed on a gravel road?

Yes, our MLSB traffic calming product line, with a 24” rebar spike or gravel earth screw can be purchased from RubberForm. These rebar spikes and earth screws should be checked periodically to make sure they have not crept up to create a hazard.

What is the reflective material on your speed bumps and speed humps?

For our MLSB2.5 we use 2 embedded AASHTO approved yellow reflectors. On our MLSB3 and MLSB4, we use a high visibility reflective yellow tape. For our RK series speed bumps and speed humps we use a special-formulated safety yellow paint with reflective glass beads.

Are these speed bumps removable, i.e., can they be moved to a new location or taken up for snowplows during the winter season?

Yes, if you need to remove them for the winter, just unbolt or unscrew the bolts/screws and store for the season. Seal the holes with Eco-Bond so water, dirt and rocks do not get lodged in the holes.

How long are your speed bump/speed hump sections?

Our line of MLSB speed bumps come in 36” long pieces that connect with a dovetail, allowing you to create the length you need. Our RK series speed bump and speed humps come in 24” sections that link together with a special dual-flange connector which also allows you to create any length you need.

What is the rubber material your speed bumps and speed humps are made of?

We have custom-formulated the right material for hard traffic over many years of use. We use masticated recycled rubber, which is harder and more durable than virgin clay-filled rubber or crumb rubber and poly compounds.

What is the turnaround time for your speed bumps and speed humps?

Our speed bumps and speed humps are in stock and can usually be shipped out the following day. Larger orders (greater than 100 units) may take a little longer - please provide us enough time to manufacture and let us know when you will need delivery.

Are your speed bumps and humps truly made in the USA?

RubberForm is one of the only true U.S. manufacturers of rubber speed bumps and speed humps. They are made from domestically sourced scrap tire rubber, manufactured, and assembled in the U.S. We believe that this is the only way to maintain our high standard of quality control.
