In the last years, according to the EC Directive 96/53/EC, in several European countries Long and Heavy Vehicles (LHV), weighing up 60 t, are adopted instead of usual Heavy Good Vehicles (HGV), weighing up 44 t. Despite of their effectiveness in terms of decrease of pollutant emissions and cost reduction, LHVs could result too much demanding for existing infrastructures, in particular for bridges. In order to evaluate the impact of LHVs on EC1-2 static and fatigue load models, in the paper the effects of the Auxerre (F) traffic, on which the EC1-2 models are based, are compared with those induced by the Moerdijk (NL) traffic, containing a relevant number of LHVs. The obtained results demonstrate that EC1-2 models cover satis-factorily also these new traffic trends.

Abstract
In the last years, according to the EC Directive 96/53/EC, in several European countries Long and Heavy Vehicles (LHV), weighing up 60 t, are adopted instead of usual Heavy Good Vehicles (HGV), weighing up 44 t. Despite of their effectiveness in terms of decrease of pollutant emissions and cost reduction, LHVs could result too much demanding for existing infrastructures, in particular for bridges. In order to evaluate the impact of LHVs on EC1-2 static and fatigue load models, in the paper the effects of the Auxerre (F) traffic, on which the EC1-2 models are based, are compared with those induced by the Moerdijk (NL) traffic, containing a relevant number of LHVs. The obtained results demonstrate that EC1-2 models cover satis-factorily also these new traffic trends.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
