New design codes of pavements and bridges tend to be less conservative than the older ones. Thus, infrastructure ageing and fatigue combined with traffic evolution result in reducing step by step the safety margins, with increased risks of severe accidents or costly road rehabilitation programs. Reversely, a more accurate knowledge of heavy traffic loads combined with advanced monitoring techniques allows better assessing the condition of the infrastructure. Higher performing calculation and extrapolation methods, incl. probabilistic approaches, are able to accurately quantify the deteriorations, to predict potential structural failures, and to take any preventive measures needed, to reduce the maintenance costs and the risks for the persons.
Papers shall present new development in tools and methods for the assessment and monitoring of road infrastructure condition in relation to heavy vehicles loads.
