Each layer of loose paving thickness should be 30cm, paving the last degree should be uniform, the surface should be smooth after compaction.

The concrete are pre-mixed concrete, delivered to site with mixer car and then pumped into forms. The paving thickness shall be 15~20% higher than the designed value.

The important parameters that influence the mechanical property of the paving layer on an orthotropic steel bridge deck are the paving layer thickness and modulus of the asphalt concrete surfacing.
