VIBRAFLEX® AREMA
Bridge Deck Protection Course

DESCRIPTION
VIBRAFLEX Bridge Deck Protection Course is a multi-ply, semi-rigid asphaltic panel composed of a mineral-fortified asphalt core between one liner of asphalt-saturated felt and one layer of fibreglass. One liner is weather-coated and has a polyethylene film facing.  It may be used in conjunction with most types of built-up dampproofing and waterproofing membranes, including liquid membranes, sheet membranes of EPDM, butyl, neoprene rubber, polyvinylchloride, as well as built-up systems. It is equally adaptable to concrete, wood, steel and pre-stressed or pre-cast concrete structures that require waterproofing. VIBRAFLEX Bridge Deck Protection Course is ideal for both new and remedial waterproofing applications. The American Railway Engineering & Maintenance of Way Association (A.R.E.M.A.) has approved VIBRAFLEX Bridge Deck Protection Course as a component within the waterproofing system, having passed five million cycles of vibratory load testing.

USES
Developed by W. R. MEADOWS in conjunction with some of the U.S.A.’s leading railroads, VIBRAFLEX Bridge Deck Protection Course provides a top-quality protection course that can be dry installed and is fully compatible with butyl sheeting and most advanced waterproofing membranes. VIBRAFLEX AREMA will withstand forces that would otherwise injure or deteriorate the membrane waterproofing material and destroy the integrity of the waterproofing system.

SPECIFICATIONS
A.R.E.M.A. Specification; Chapter 29 for Membrane Waterproofing.

FEATURES AND BENEFITS
    • Large 1.22 m x 2.44 m (4’ x 8’) panels can be installed dry, permitting faster, easier installation and a savings of 40 - 60% in total installed costs
    • Panel size results in fewer joints (90% less) which eliminates infiltration of fines and resulting damage to the waterproofing membrane
    • Flexible dual-layer installation complies with the current A.R.E.M.A. Specification in Chapter 29. E
    • Eliminates messy hot-mopping and cold-bitumen adhesives
    • The factory-applied, weather-coated surface permits controlled ballast penetration for a secure seating position which locks the panel to the ballast for effective base stabilization
    • Backed by more than three decades of outstanding field performance and service

APPLICATION
To reduce the possible ingress and infiltration of fines and provide maximum membrane protection. VIBRAFLEX Bridge Deck Protection Course panels are installed in two layers. The first layer is laid dry directly on the waterproofing membrane, with each sheet butted tightly to the next. The second layer is then laid with the butt joints staggered on a half sheet module to avoid coincidental matching with the joints of the first layer. No adhesives are required when the sheets are applied in this dual-layer technique. The longitudinal dimension of the panels should be parallel to the composite slabs and structural members. VIBRAFLEX Bridge Deck Protection Course is shipped with anti-stick polyethylene sheets between each panel, making handling and installation fast and easy. Panels may be cut to size using a sharp roofer’s knife.

DUAL LAYOUT APPLICATION THEORY
This theory, shared by many railroad engineers, states that the longer the ballast is in place, the greater the degree of build up or concentration of fines at the lowest possible level; in this case the point at which the ballast is in direct contact with VIBRAFLEX Bridge Deck Protection Course. Normal gravitational movement, vibration movement of the ballast and liquid flowing in the direction of the membrane concentrates these fines, and gradually, a crust-like surface develops on the top of the VIBRAFLEX Bridge Deck Protection Course. Because of the staggered joint system, the fines do not work their way through the full material thickness since only one half of the total joint area is present at any one point, keeping the integrity of the waterproofing membrane preserved.

PRECAUTIONS
Keep VIBRAFLEX Bridge Deck Protection Course stacked on pallets or on a smooth surface to prevent deformation before application.  Do not apply VIBRAFLEX Bridge Deck Protection Course over liquid waterproofing membranes containing volatile solvents until all of the solvent has completely evaporated.

NOTE: WHERE VIBRAFLEX BRIDGE DECK PROTECTION COURSE WILL BE LEFT EXPOSED TO SUNLIGHT, IT MUST BE PROTECTED WITH AN APPLICATION OF ALUMINUM FIBRED ROOF COATING. SPECIFIER AND USER SHALL DETERMINE SUITABILITY OF PRODUCT FOR SPECIFIC APPLICATIONS AND ASSUME ALL RESPONSIBILITIES IN CONNECTION THEREWITH.  Read and follow application information, precautions and Material Safety Data Sheet.
