DESIGN
Road expansion joints resist sustained loads due to continuously increasing road traffic. They are also directly exposed to pollution, oil and dissolved road deicing salt.
The design of CIPEC road expansion joints and the nature of the materials used are optimised to resist all these aggressions, and they have a remarkably long life. The main elements of CIPEC expansion joints are: u metallic elements, u an anchor system, u a continuous elastomer sealing section.
Metallic elements
Metallic elements may be made either from treated aluminium or hard drawn steel, and their surface area exposed to traffic is limited, thus limiting the loads applied to them.
Metallic elements of joints with medium and large movements have triangular or straight teeth that aid the user during installation and mitigate road noise, regardless of the joint opening distance. These teeth may also be installed on skew bridges without introducing any stress on the expansion joints.
Anchor systems
CIPEC road expansion joints use one of the following two systems to anchor metallic elements to the structures to be equipped, depending on the model: u either prestressed attachments, u or a resin mortar bonding to the support (for the JEP) joint.
SPECIAL FEATURES
The JEP joint is installed within the thickness of the surface layer. It is quickly installed and because there are no recesses or drillings in the structure, the JEP joint is well suited for solving specific problems with the replacement of existing joints, work done lane by lane, renovations in which only short traffic interruptions can be accepted, and in which completion speed is all important. Traffic can be allowed over the joint after three hours. Since there are no teeth, JEP joints can accept small side movements without any change to their intrinsic qualities.
MOVEMENTS RANGE
The following table shows the capacity of JEP joints to accept movements as a function of the skew of the bridge:

WR EXPANSION JOINTS
DESIGN
These joints form part of the gap joints family. They are composed of two extruded aluminium alloy sections delivered in three-metre lengths and placed facing each other. These elements are anchored by a series of attachments slightly inclined in reinforced microconcrete beams and fixed to structures by continuity bars. A series of pairs of sections installed end-to-end forms the line of the joint.
SPECIAL FEATURES
The WR joint is installed within the thickness of the surface layer. It is installed quickly and the fact that there are no recesses in the structures makes the WR a particularly economic joint. It is suitable for new work or renovation work.

SPECIAL FEATURES
WOSd joints may easily be removed if necessary, since the anchor bolts are easily accessible and due to the method of fastening the elastomer section. The shape of the elastomer section and its position slightly below the surface enables systematic elimination of debris simply by suction caused by passing vehicles. It is easy to lift WOSd joints if resurfacing is carried out. WOSd joints can accept any amount of skew without any change to their intrinsic qualities, since there are no teeth.

Wd EXPANSION JOINTS
DESIGN
These joints form part of the cantilevered teeth expansion joints family. They are composed of pairs of independent elements with triangular teeth made of cast aluminium alloy, delivered in one-metre lengths and placed facing each other. A series of pairs of elements installed end-to-end forms the joint line. The metallic elements are anchored to the structures.
SPECIAL FEATURES
Wd joints are exceptionally robust as a result of the principle used to connect metallic elements to structures based on the choice of materials used, and a controlled method of installation. They are designed for heavy and frequent traffic. The triangular teeth of the metallic elements enable operation with no gap and thus enable perfect traffic continuity with a significant reduction in traffic noise over the joint, regardless of its opening dimension.
The easy access to anchor bolts and the short length of the elements facilitate maintenance and removal of the Wd joint without interrupting traffic, except on the lane being repaired. Wd joints accept a skew of 30 gr without any change to their intrinsic qualities.
MOVEMENTS RANGE
The following table shows the capacity of Wd joints to accept movements as a function of the skew of the bridge:

WP EXPANSION JOINTS
DESIGN
These joints form part of the cantilevered teeth expansion joints family. They are composed of pairs of independent elements with parallel teeth delivered in one-metre lengths and placed facing each other. These teeth are cut from a rolled steel plate, or cast from aluminium alloy. A series of pairs of elements installed end-to-end forms the joint line. Metallic elements are anchored to structures using controlled tightness fasteners.
The WP joint may be used with a system for recovering runoff water. This system is composed of a continuous elastomer looped membrane over the entire length of the joint line or two elastomer membranes with a gutter located under the joint.
SPECIAL FEATURES
WP joints are made on request and may be adapted to the direction of displacement of the structure, either straight (fig. 1) or skew (fig. 2). Their capacity may vary from 250 to 1000 mm depending on the model.
