How is highway loading addressed in the Eurocodes?
Normal highway loading is specified in Eurocode 1 Part 2 and supplemented by provisions in the National Annex. This load model comprises a tandem axle system acting in conjunction with a uniformly distributed load. Abnormal loading is specified in the National Annex to Eurocode 1 Part 2. The forthcoming Interim Advice Note will specify which special vehicle load model is appropriate depending on the type of highway.
