Die aktuell in Deutschland genutzten Verfahren zur Beurteilung der Substanz basieren vorwiegend auf der Analyse des Zustands der Oberfläche. Die Zielsetzung des vom Bundesministerium für Verkehr und digitale Infrastruktur beauftragten Forschungsprojekts „In‐Motion“ aus dem nationalen Innovationsprogramm Straße bestand darin, mithilfe verschiedener zerstörungsfreier Verfahren die strukturelle Substanz...
To determine a feasible strategy for maintenance and rehabilitation of in-service asphalt pavements, the precise in-situ determination of pavement deterioration is of significant importance. Conventional methods such as fatigue tests on core specimens in the laboratory or stationary deflection measurements in-situ exhibit their own disadvantages. This study proposes an innovative system to measure...
A specific computational program SAFEM was developed based on semi-analytical finite element (FE) method for analysis of asphalt pavement structural responses under static loads. The reliability and efficiency of this FE program was proved by comparison with the general commercial FE software ABAQUS. In order to further reduce the computational time without decrease of the accuracy, the infinite element...
