ABSTRACT
Abstract This contribution describes the rehabilitation of old cement concrete roads. Before deciding how to repair the roads, different solutions were tested on short test sections. Depending on bedding o f slabs and heavy-duty traffic volume different types of unbounded and bituminous courses were used. The development o f reflective cracks over the transverse joints was observed and recorded. The evaluations o f the tests showed relevant information for the future work. Keywords: Concrete pavement, deflection measurement, rehabilitation, test section
In Carinthia, the southern region o f Austria, about 70 km of the federal roads were constructed with concrete pavements in the fifties. The pavement consists o f following two courses.
