Composite Advantage picks new wear surface option for its bridges

Matacryl, which combines quartz aggregate in a methyl methacrylate polymer, is said to offer the durability and toughness Composite Advantage requires for its composite bridges and other structures.

Composite Advantage (CA, Dayton, OH, US) has introduced a new wear surface option for its FiberSPAN pedestrian bridge deck and rail platform products. After evaluation and testing, CA selected the Matacryl system, which combines quartz aggregate in a methyl methacrylate polymer for greater durability, less roughness and higher elongation than conventional non-slip wear surfaces. The product is similar to the polymer concrete surfaces used on vehicle bridges.

“FRP decking is continuing to gain ground in pedestrian bridge and rail platform projects,” says Scott Reeve, president of Composite Advantage, “especially in larger cities where these types of structures endure the wear and tear of daily foot traffic and seasonal activity like snow removal. The demanding requirements of these rugged environments prompted adaptation of Matacryl to these types of applications.”

Matacryl has been used in Europe extensively, but was just recently introduced to North America. Its 0.25-inch wear surface has been UL tested for fire resistance. The product weighs 2 lb/ft2 and costs just a few dollars more per square foot than a traditional wear surface product, while lasting up to five times longer. High elongation (more than 100%) allows the surface to withstand high impact at cold temperatures. Matacryl comes in a variety of colors and is immune to UV radiation and fading.
