1 CIPECE xpansion Jointsexpansion jointsCIPECCIPEC expansion joints are designed to enable continuoustraffic between two structures, accommodating structuralmovements due to creep, shrinkage effects, temperaturevariations and deformations under live are suitable for all reinforced concrete, prestressedconcrete, composite and steel structures,and particularly for bridge expansion joints are also designed to allow sufficientvertical movement so that bearings can be replaced withoutneeding to disassemble the expansion enable drainage of runoff water and theyare designed to minimize traffic movement expansion jointsMedium movement expansion jointsLarge movement expansion jointspage 3: JEP jointspage 5: WR jointspage 7: WOSd jointspage 9: Wd jointspage 13.

They are also directly exposed to pollution, oil and dissolved roaddeicing design of CIPEC road expansion joints and the nature of the materialsused are optimised to resist all these aggressions, and they have a remark-ably long main elements of CIPEC expansion joints are:umetallic elements, uan anchor system, ua continuous elastomer sealing elementsMetallic elements may be made either from treated aluminium or hard drawnsteel, and their surface area exposed to traffic is limited, thus limiting the loadsapplied to them.

4 Depending on the model:ueither prestressed attachments, uor a resin mortar bonding to the support (for the JEP) elastomer sectionA continuous elastomer section over the entire length of the road surfaceexpansion joint is inserted between metallic elements. It prevents the pene-tration of foreign bodies and provides waterproofing against runoff section is installed underneath the surface layer and does not resist traf-fic of the elastomer section at the ends of the joint line also contributeto the leak tightness of the joint. A drain installed on the upstream side of thejoint line also helps by collecting any water that infiltrates through the road sur-face OF CIPEC EXPANSION JOINTSA badly designed expansion joint, or simply a wrong choice of an expansionjoint, can cause severe and irreversible disorders for itself and for the struc-tures on which it is joints are designed for quality, and are very much appreciated for thebenefits that they provide as has been demonstrated on many structural pro-jects for more than 30 years:uexcellent traffic comfort;ulong life;ulow noise;uhigh resistance to corrosion;uno horizontal reaction.

5 Ve rtical movements of stru c t u res are possible (for jack-ing, etc.) without the need to disassemble the joint;uprotection of surfaces under the joint;ugood resistance to heavy duty and frequent traffic loads;uadaptability to all surface structure types;ueasy installation on new or old structures;ulow servicing and Expansion Joints / Small Movements 3 JEP EXPANSION JOINTSDESIGNT hese joints form part of the gap joints family. They are composed of two sec-tions of drawn steel delivered in three-metre lengths and placed facing eachother. These elements are equipped with two sinusoidal anchor parts cast intoa resin-based mortar beam bonded to the joint line is formed by a sequence of pairs of sections welded end to FEATURESThe JEP joint is installed within the thickness of the surface layer.

6 It is quicklyinstalled and because there are no recesses or drillings in the structure, theJEP joint is well suited for solving specific problems with the replacement ofexisting joints, work done lane by lane, renovations in which only short trafficinterruptions can be accepted, and in which completion speed is all can be allowed over the joint after three there are no teeth, JEP joints can accept small side movements with-out any change to their intrinsic in (100 gr) gr37629960 gr518513640 grMOVEMENTS RANGEThe following table shows the capacity of JEP joints to accept movements asa function of the skew of the bridge:4 CIPEC Expansion Joints / Small MovementsACCESSORIESThe following accessories are available to make the surface layer completelywatertight at the joint and to make the action of the joint effective over thefootpath (and other areas not carrying traffic): upavement joints - ;uend section upstands - fig.
