Abstract:

The majority of the bridges in Kansas are in rural areas. Many of these are ; becoming structurally deficient, and are in need of replacement. Due to the location of ; these bridges, cost of transporting prestressed girders to these areas often makes use of ; cast-in-place bridges more economical. Use of lightweight aggregate in these bridge ; girders would reduce the total weight and could allow multiple girders to be shipped on ; one semi-truck. This would reduce transportation costs and allow the more economical ; prestressed girders to be used in rural areas. Lightweight prestressed girders could be ; put in place using a lower capacity crane due to the lower self-weight of the beam. The ; construction process would be quicker without the need of form work associated with ; cast-in-place girders. The lighter self-weight would also increase allowable live loads ; the bridges would be able to carry.
