The vialytics Road Management System detects a variety of different damage classes. Here you will find an overview.
Outbursts
|
Potholes are missing asphalt parts that usually occur in connection with cracks. Due to their depth and the associated risk of injury, immediate repair measures are necessary. The subsoil can be loose, stony, or earthy. |
|
|
|
Outbursts are asphalt parts that have broken out of the roadway. These can either affect only the asphalt surface, or also the underlying layers. The subsoil can be flat, stony and loose. |
|
 |
|
Grain break-outs are individual pieces of rock that have broken out of the asphalt. The damage is on the asphalt surface and has an uneven subsoil. |
|
 |
|
Flakings are missing pieces of asphalt. The underlying asphalt layer is intact and visible. The flaking has a clear, mostly roundish/oval shape. |
|
 |
|
Layer strippings are a detachment of the surface course. They result from high traffic volume, insufficient binder content or weathering. |
|
 |
|
Edge ruptures are broken-off pieces of asphalt that are located at the roadside. In this case, the edge piece has broken off down to the subsoil. |
|
 |
Cracks
|
Single cracks are individually occurring asphalt openings that usually extend in a jagged pattern along and across the roadway. |
|
|
|
Gaping cracks are single asphalt openings that usually occur in a lightning pattern along and across the roadway. The second asphalt layer or deeper layers are affected. |
|
 |
|
Cluster cracks are light asphalt openings that can extend over a small or a large part of the roadway. These are multiple cracks that may connect to or originate from each other. |
|
 |
|
Gaping crack clusters are asphalt openings that can extend over both a small and a large part of the roadway. The second asphalt layer or deeper layers are affected. They are multiple cracks that may connect to or originate from each other. |
|
 |
|
Alligator cracks are asphalt openings that extend in a mesh over part of the road. The characteristic feature of this type of crack is the regular meshes that form the alligator crack. |
|
 |
|
Filled cracks are cracks that have been sealed with bitumen. The shape of the cracks remains the same. The filled crack is usually darker than the road surface and shows a width of approx. 5 cm. |
|
 |
Joints and seams
|
Open joints are mechanically created asphalt openings. This straight-line gap is created during repair work, among other causes.
|
|
|
|
Open seams Open seams are straight asphalt openings located in the center of the road.
|
|
|
|
Gaping seams are straight asphalt openings located in the middle of the road. In this case, the second layer or deeper layers are visible. |
|
|
|
Open construction stops tend to run in a straight line and occur due to production stops and at road junctions. |
|
 |
Patches
|
Patches can be recognized by the straight-cut edges, usually different-looking surface structure and asphalt coloring. The edges are either untreated, i.e. open, or have been closed with bitumen compound or bitumen tape. |
|
 |
|
Surface patches have an irregular shape and lie on top of the asphalt. |
|
 |
|
Sprayed patches are usually darker than the roadway. The shape varies depending on the processing procedure. |
