Joint-Design on Concrete Motorways in Austria

A recently finished study at the Research Institute of the Association of the Austrian Cement Industry and the Institute for Road Construction and Maintenance, Technical University Vienna focuses on the improvement of the joint design on concrete roads. The main issues of this study are presented in this paper. Special attention is paid to the construction of the joint, especially to the sealing of the transverse and longitudinal joints and to selective measures to drain the pavement underneath the joint. Recommendations for the optimization of the construction of concrete pavements are given.
