1 EXPANSION JOINTS

2 The EXPANSION JOINTS are structural components that perform a continuity function on the rolling surface and enable movements between the decks. Indeed, the structural joints are necessary to compensate the displacements, generally due to: Hygrometric removal of the concrete; Thermo dilatation of the deck; Wind actions; Slowing down actions; Seismic actions. The expansion joints of SOMMA have a range of movement FROM 20 TO 1200 MM, their external agents. provide maximum comfort for passengers in transit.

The value of the joint s displacement depends on the quantity of rubber modules in the joint. The elements are disposed to make sure that, if the joint is vertically cut, a reinforcing element is always found. The materials are according to CNR10018/98 standard.

21 RAILWEJ RAILWAY JOINT The railway joints are designed with special care to be suitable for railway structures and meet the requirements imposed by RFI. In particular, dielectric rubber is used and a stainless steel plate is provided on the upper surface of the joint, to prevent the ballast from getting inside.

22 INSTALLATION The installation of the joint must take place after a occur near the joint, because the high strength mortars used prevent every lowering. Therefore It is advisable to install the joints after at least 6 Alternatively we invite you to increase the vibro-rolling near the joint, in order to reduce the the gaps and to limit as much as possible the subsequent settling of the pavement. PRELIMINARY PHASE 1) Cut of asphalt. 2) Removal of the paving and bush-hammering. 3) Placing of the drainage system. 4) Preparation of the site of the joint. 5) Casting of mortar or shrinkage compensating grout to create the support surface of the joint. 6) Tracing holes. POSITIONING OF THE JOINT 1) Positioning of the panels of the joint (in the case of loads over 30 kg, use a lifting tool). 2) Drilling and grouting of anchors. 3) Tightening of the anchor nuts with torque indicated on the project. 5) Sealing of the housing slots for the anchors until
