This working paper summarises the current state of knowledge and research on the application of sensors in road pavements, designed to record input quantities and characteristics for structural assessment. In this working paper, sensors generally refer to technical equipment that can used to record the values of physical quantities and display them for interpretation.
The working paper deals with every type of sensor that is permanently connected to the road, i.e. sensors that are installed – in the bound and unbound courses of the superstructure as well as in the sub-base/sub-structure, – next to or above the road (for example on masts) and can contribute to structural recording and its subsequent assessment. This can also include sensors that are primarily used for a different purpose (e.g. traffic control). However, this working paper only describes the application of sensors that are installed primarily for other purposes for the sake of completeness; special publications (e.g. Notes on detection technologies in road traffic) are available for the respective installation situations.
Das vorliegende Arbeitspapier stellt den Stand des Wissens und der Forschung zum Einsatz von Sensorik in Straßenbefestigungen zur Erfassung von Eingangsgrößen und Merkmalen für die Substanzbewertung zusammenfassend dar. Unter Sensorik versteht dieses Arbeitspapier ganz allgemein technische Einrichtungen, mit denen man die Werte von physikalischen Größen erfassen und zur Interpretation darstellen kann.
