Product List of
Bridge
Compression Seals
Preformed
Elastomeric Joint Seals shall be specified on the contract documents
when applicable to projects. Each seal shall be specified by a Movement
Rating, which shall be the design movement of the bridge, (30 mm/30
m). At fixed joints a Movement Rating of 13 mm is specified unless
an engineering evaluation of the joint geometry indicates the need
for a larger value. Listed below is a table of Compression Seals
prequalified for the Movement Ratings and Maximum Skew Angles indicated.

*Use
for retrofitting of existing joints only!
- Notes:The
Movement Rating shown is to be used as the actual movement of
the joint Parallel to the direction of expansion. Although the
Standard Details show a Movement Rating at 7° C to
be normal to the centerline of bearings, no reduction in the Movement
Rating will be made for skewed structures. This will compensate
for movements in the transverse direction.
- Seals
of 102 mm nominal width at skew over 15° and all seals
wider than 102 mm will exceed the 89 mm max. joint opening allowed
and should only be used in combination with plates or other means
that will reduce the joint opening at the pavement surface to
89 mm or less.
- Special
design consideration is required for skew between 30°
and 50° back on the right (skewed either way on the
Interstate) because of the danger of a snowplow blade catching
in the joint.
