Measurement of Deflections and Determination of Jointed Plain Concrete Pavements Stiffness by Falling Weight Deflectometer

Within the the National Sustainability Programme I, project of Transport R&D Centre (LO1610), the determination of measured jointed plain concrete pavements deflections to load was monitored. Impacts of climate and other effects upon resulting concrete pavement deflections were studied in the first place. The main issue for FWD measurements is the selection of suitable climatic conditions.In addition, loading transfer efficiency (LTE) at slab joints, which is a specific feature of concrete road pavements, was studied.
