Axle Load Survey
An Axle Load Survey measures the weight per axle of vehicles to evaluate pavement loading and structural adequacy. It informs pavement design, maintenance planning and enforcement of legal load limits.
Weigh-in-Motion (WIM): Portable or fixed WIM sensors record axle weights and spacing at highway speeds.
Static Weighbridges: Calibration and spot checks using portable weighbridges for enforcement and validation.
Load Spectrum Analysis: Distribution of axle loads by class and time, used for fatigue life estimation of pavement layers.
Overload Detection & Reporting: Identification of overloaded vehicles to support regulation compliance.
Reporting: Comprehensive axle-load histograms, classification summaries and recommendations for pavement strengthening or load restrictions.
