Non-Destructive Testing of an Experimental Pavement

摘要

The present article relates to the non-destructive testing of a flexible pavement. Anrnexperimental pavement is designed for studying the behavior of different types ofrnflexible pavements, monitoring their evolution over time and locate artificial defectsrnbuilt during the construction such as compacting defects of unbounded granular material,rnbond defects between bituminous layers and transverse cracks. This pavementrnwas instrumented with various sensors that allow measuring: temperature and moisturernin the individual layers and at their interfaces. The diagnosis tools presented herernare based on the mechanical waves (IE and FWD) and electromagnetic wave (GPR)rnpropagation and were tested on the experimental pavement.
