The dowel bars embedded in concrete pavements transfer the load across the development joints. When aligned adequately, they assist cut down faulting and Enhance the pavement’s effectiveness.
They may be presented for transferring the load from just one member to your adjacent member for instance a person slab adjacent to the closest.
