Axle load control: why overloading matters and how systems help
By Vicky Ogola, Senior ICT Consultant 1 min read
Pavement damage rises steeply with axle load. Modern load control combines screening, weighing and data to protect roads without stopping all traffic.
Roads are designed for a certain number of passes by axles of a certain weight. Overloaded axles consume that design life disproportionately faster, which is why axle load limits exist and why they are enforced.
The limits
In East Africa, vehicle load limits — per axle group and for the whole vehicle — are set by the EAC Vehicle Load Control Act, 2016 and applied by national road agencies. Systems must be configured to the current limits and axle configurations.
Where traditional weighing struggles
Static weighbridges are accurate, but every vehicle must stop. Queues form, compliant vehicles are delayed, and in practice only a fraction of traffic can be checked.
How a modern system works
- **Screening:** weigh-in-motion sensors and cameras check vehicles at speed.
- **Selection:** only vehicles likely to be overloaded are directed to the static weighbridge.
- **Weighing:** the static weighbridge produces the measurement used for any decision.
- **Records:** software links weights, images, number plates and decisions in one auditable record across stations.
What the data adds
Load patterns by route, time and operator help agencies target enforcement and plan maintenance, and help operators manage their own compliance.
