• The Wabo®BusTuff system absorbs impact and carries axle loads up to and including 40,000 pounds

• Handles 30% horizontal impact forces created by large vehicles traveling at high speeds across the system

• Accommodates slab movements in all directions while eliminating failure modes most often associ-ated with plate-type systems

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.

Designed and proven to accommodate high load, high speed, high daily traffic count parking deck challenges.

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.

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 ten-sion 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.

For Best ResultsTips 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 compo-nents 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
