Cross laminated timber (CLT) is a new type of engineered wood panel consist of several layers of structural lumber boards stacked crosswise at 90° angles and glued together on their faces. It is possible to produce CLT panels of 3 m wide, 12 m long, and 270 mm thick. CLT is light-weight material which the unit weight of CLT made of Japanese cedar is about 1/6 of reinforced concrete, therefore it's has advantage in terms of the transport and construction works. The authors consider using CLT elements for bridge deck replacement instead of a concrete deck slab. The overview of the design and construction of the bridge deck replacement of an existing bridge using CLT srlabs is reported herein.
