Load Transfer Restoration LCPC Freyssinet Connector

Paper by ORSAT from ISCR 6th 1990

The LCPCIFREYSSINET slab connector is an innovating device allowing load transfer restauration of concrete roads submitted to pumping effects. It is constittïed by two synietrical half-shells in cast iron glued to a central elastomeric pad and contains an adjusted steel-pin which slides freely within housings machined in the shells, making possible an horizontal displacement while locking vertically. They are firmly inserted in blind holes preliminary drilled, a sealing resin, initially poured in the holes before insertion insures a proper bonding. A high output duty installing machine is able to treat 1 km of road per day. This paper describes a site (performed by night) of instalation of 6700 units with measurements carried out and results obtained.
