The Semi-rigid Wearing Courses in Austria (HSD)

Concrete wearing courses with their high deformation stability could be an alternative to asphalt wearing courses here, but these have other disadvantages besides their high production price. The gap between these two different types of wearing course is being bridged by the relatively new construction method of semi-rigid wearing courses. This construction method uses the technological properties and advantages of the flexible asphalt construction method and combines them with those of the rigid concrete construction method.
