The full definition of wheel load on road?  how many types and how to calculate wheel load?

Wheel load on a road refers to the amount of weight that is supported by a single wheel or group of wheels on a vehicle. It is an important factor to consider in the design and maintenance of roads, as excessive wheel loads can cause damage to the road surface and shorten its lifespan.

There are two main types of wheel loads:

Static Wheel Load: This is the weight of the vehicle and its cargo that is supported by a stationary wheel.

Dynamic Wheel Load: This is the additional force that is exerted on the road surface by a moving wheel. It is influenced by factors such as the speed of the vehicle, the suspension system of the vehicle, and the characteristics of the road surface.

To calculate the wheel load, the weight of the vehicle and its cargo is divided by the number of wheels that are in contact with the road surface.

 For example, if a vehicle weighs 4,000 pounds and has four wheels, each wheel would be supporting a static wheel load of 1,000 pounds.

However, for dynamic wheel load calculations, additional factors such as the tire pressure, the speed of the vehicle, and the number of axles also need to be taken into account.

It is important to note that the maximum allowable wheel load will vary depending on the type of road and its design specifications. Road engineers and designers use a range of formulas and standards to calculate the maximum allowable wheel load for a given road surface, taking into account factors such as the thickness of the road surface, the materials used, and the expected traffic volume.
