Why should the bridge be strengthened?

1) During the use of the bridge, any bridge will become an old bridge.

People have limited knowledge of pavement function of early built bridge, , so there are diseases, for example small reinforcing bars, small diameter steel, pavement and the bearing component interface continuous uncertainty problems. Therefore, the reinforcement and retrofitting of the old bridge has become inevitable.

2) From the economic analysis, the bridge reinforcement can save a lot of investment and receive good social and economic benefits.

Using appropriate technology and broaden the reinforcement measures can not dismantle the old bridge and built a new bridge, so as to reduce the engineering cost a lot; and some can be done without interrupting traffic conditions, but also to restore and improve the bearing capacity of old bridge and traffic capacity, prolong the service life of the bridge, to meet the modern transportation demand.

3) The retrofitting and reinforcement of the bridge can not only improve the capacity and service level of highway bridges, but also eliminate the hidden dangers of traffic safety to a certain extent.
