Aplicación del pesaje de vehículos en movimiento al dimensionamiento de firmes. Influencia de la precisión de los pesajes

Abstract

Weigh-in-motion (WIM) techniques can provide data on vehicle and axle weights when they are travelling at full highway speeds. In this paper, the application of WIM data to the design of road pavements is described and the effect of WIM load data accuracy on the estimate of pavement service life is analysed. Thus, the main factors affecting WIM accuracy are explained, especially those related to vehicle-pavement interaction. Afterwards, a trial that has been conducted to evaluate the effect of WIM load data accuracy on pavement life prediction will be presented. The results obtained show that the errors in axle load measurements can lead to higher errors in pavement life estimates.
