The axle load of a wheeled vehicle is the total weight bearing on the roadway for all wheels connected to a given axle.Axle load is an important design consideration in the engineering of roadways and railways, as both are designed to tolerate a maximum weight-per-axle (axle load); exceeding the maximum rated axle load will cause damage to the roadway or railway tracks.
Strength depends upon material properties. The strength of a material depends on its capacity to withstand axial stress, shear stress, bending, and torsion.The strength of a material is measured in force per unit area (newtons per square millimetre or N/mm², or the equivalent megapascals or MPa in the SI system and often pounds per square inch psi in the United States Customary Units system).
When evaluating the series of tests, it was found that there is a connection between the thickness of the pavement, the number of load transfers and the axle load, and that these have a direct effect on the service life and condition of a road. The service life of the road is thereby reduced with approximately the fourth power of the axle load. [1]
The wheel and axle assembly can be considered one of the six simple machines. Wheel and axle – a machine consisting of a wheel attached to a smaller axle so that these two parts rotate together in which a force is transferred from one to the other. The wheel and axle can be viewed as a version of the lever, with a drive force applied ...
A super dump is a straight dump truck equipped with a trailing axle, a liftable, load-bearing axle rated as high as 13,000 pounds (5,897 kg). Trailing 11 to 13 feet (3.35 to 3.96 m) behind the rear tandem, the trailing axle stretches the outer "bridge" measurement—the distance between the first and last axles—to the maximum overall length ...
A tandem axle is defined as two or more consecutive axles whose centers are spaced more than 40 inches (102 cm) but not more than 96 inches (244 cm) apart. [10] Axles spaced less than 40 inches (102 cm) apart are considered a single axle. [11] In effect, the formula reduces the legal weight limit for shorter trucks with fewer axles (see table below

A weighbridge is very robust and durable due to its construction like a static track scale. Disadvantages: No determination of wheel load and axle loads, however, the design can be expanded to include integrated axle load and wheel load measurement with force sensors in the track.
