Why Bridges Freeze Before Roads Do

Written by Leonard D'Orlando, November 29, 2018

We should pay special attention to bridges and overpasses when driving in temperatures around the freezing point. Over the years we have heard that bridges may be icy while the road is not. We have also seen signs posted before bridges and overpasses which state this for safety reasons. This condition however is an important one that should be given some consideration. So how could the bridge be icy when the road is not? Here’s why.

Solutions for other slippery conditions

Written by Ulrik Andersson, November 1, 2018

The automatic snow chains are genius when you encounter adverse road conditions in the colder seasons. With just a flip of a switch you have instant traction added so that you can get up in speed or if you need to stop, you get improved breaking power.

 

But what about the rest of the year, when you are not in the winter season? In the middle of the summer or in the autumn?

4x4 vs. Onspot

Written by Leonard D'Orlando, October 12, 2018

There are times while working the booth at a trade show that people will tell me they are considering the Onspot automatic tire chain system, but are also considering 4X4 as well. When purchasing a new vehicle, 4x4 is a common option to consider. No wonder, since it’s a familiar and well-tried solution with good features for safer driving, but it is also easy to ignore its weaknesses and believe that there is no better alternative.

What is road friction?

Written by Maritza Hernandez, September 17, 2018

Friction and traction are key to avoid sliding vehicles and spinning wheels.

Friction is defined as the rubbing of one object or surface against another. The friction between your vehicles’ tires and the road will determine maximum acceleration and minimum stopping distance. The force of friction depends on the force pushing the objects or surfaces together and the coefficient of friction. The coefficient of friction is the relationship between the force required to move the surfaces against each other and the pressure to stay in contact while in motion.

Surface Treatments

Written by Leonard D'Orlando, February 22, 2018

Which is the perfect road surface treatment to increase traction?

To keep transportation – and society – running, authorities have different strategies for keeping roads open and driveable in harsh winter conditions. Snowplows keep the snow masses away from the road, and often some kind of surface treatment is used to increase traction when roads are icy and unsafe. But, which is the perfect road surface treatment? The simple answer is... None! Every method of surface treatment is a compromise between effectiveness, cost, handling and side effects. Let's have a look at some methods.
