The road pavement condition is a ected by various impacts such as trucks, deicing reagents, base erosion, etc. After some time on the road surface occur defects. Engineers are commonly used to collect pavement surface distress data, during periodic road surveys, but it takes a lot of time and manpower. In this paper, we present our automatic defects detection and classi cation on road pavement ...

Natural pavements are an important element of flights. Among other things, they allow the plane to be safely slowed down after it has exited runway. For this reason, load bearing capacity natural airfield and strength turf layer at a specified level required. Currently used testing methods, such as CBR (Californian Bearing Ratio) tests or probe test, separately do not give full image pavement t...
