Wabo®BusTuff (BTS)
Heavy duty expansion joint system
US Patent No. 8,267,617
Designed and proven to accommodate high load, high speed,
high daily traffic count parking deck challenges.
This system has also been designed and tested to withstand the most demanding seismic events, resulting
in the most fully functional expansion joint system in the marketplace.
Successful seismic testing of the BusTuff system was conducted in 2012 at the Pacific Earthquake
Engineering Research (PEER) Center, University of California, Berkeley. This system will effectively handle up
to a Magnitude 8 seismic event, allowing for continuous use during and following significant seismic activity.

Technical System Data
Each Wabo®BusTuff expansion control system is specifically designed to
suit individual project conditions.
Considerations for use are high loads (vehicles higher in weight than
passenger vehicles and pickup trucks i.e. oscillating buses), vehicles
traveling at speeds in excess of 20 miles per hour, transitions in elevation
across opposing decks, and locations where large vehicle count-per-day
exists.
Tips to do it right.
•• Install when concrete substrate is clean, sound, dry, and cured
•• Do not allow any of the Wabo®Crete II elastomeric concrete components to freeze prior to installation. Store all components out of direct
sunlight in a clean, dry location between 50˚F (10˚C) and 90˚F (32˚C)
•• Shelf life of chemical components is 1 year
•• Periodically inspect bolt hole filler and edge void sealant and repair
localized areas as needed
•• For water management, minimize drain trough (optional) splice points
by installing it in longest possible continuous lengths
Our technical staff can provide the highly skilled engineering services
required to transform design considerations, joint opening(s), and thermal
and/or seismic movements into a maintenance-free system built to last.
In fact, each BusTuff system developed is analyzed with Finite Element
Analysis (FEA) as part of the standard engineering process.
Preassembly and shorter sized panels allow for quick lane-by-lane
installation on retrofit applications.
Physical System Properties
QuietRideTM Technology – ensures no “plate slap” of metal to substrate due to repeated heavy
loading. Factory poured high density polyurethane pads are kept in constant contact to the
adjacent structure by “pre-tensioning” the system’s hardware which are installed to a specified
torque. Specially designed non-metallic compression springs maintain specified hardware tension throughout the expansion joint’s service life.
Wabo®Crete II Elastomeric Header – a key component to QuietRideTM Technology, this
elastomeric header absorbs traffic impact loads and evenly disperses them into the deck slab,
while allowing the system to flex with deck loads.
Steel Edge Members – all steel members and cover plates are manufactured from structural
steel, and are designed by WBA Engineering staff to properly carry loads, limit deflection, and
account for infinite fatigue life.
Slip Resistant Coating – high coefficient of friction slip resistant epoxy coating factory applied
to ensure years of service under the most aggressive environments.
