A dynamic weighbridge provides information on the spectrum of axle loads on a given road. Throughout the last decade, there has been increasing awareness in many countries of the need for this kind of information, against a background in which existing road networks were being tested to the limit by a steady increase in road transportation of goods. The point is that, as is well known, a greatly disproportionate amount of the damage to road structure is due to heavier axle loads. It is particularly true in Ireland that, in recent years, the road network is approaching a critical state. Axle load spectra are important as input to overlay and new road design schemes and also for bridge design. Dynamic weighbridges may also be used as preselectors in an enforcement scheme, if placed upstream from a static weighbridge installation. They may also give traffic flow information and vehicle speed data. The Saskatchewan model in fact can do all of these things.
