Joints and seams in
asphalt and concrete
Diverse solutions for rolling trafficThere are multiple causes for damage to asphalt and concrete roads: Roads that are designed improperly, excessive use and damaging environmental influences are a drain on public finances.
The weakest points in roads are joints, seams and connections in asphalt and concrete.
- Joints are spaces between two asphalt or concrete layers, or between their layers or components, such as kerbs, manhole covers etc. These joints are either intentional or necessary for the working situation in question.
- Seams are contact surfaces that are created when asphalt mix is laid in lanes, alongside or near to breaks in the application of the asphalt (longitudinal or lateral seams).
- Connections are contact surfaces between different asphalt mix types (e.g. rolled asphalt & poured asphalt) or around components, e.g. near kerbs, plaster etc.
