Tensar International is rolling out a line of new products to address specific needs of pavement surfaces in several areas.

Tensar has been working since 2009 to develop Endurablend Systems, a family of advanced polymer cement slurry surfacing (PCSS) products that provide a flexible yet durable barrier over asphalt and concrete pavements. By addressing specific pavement needs before the onset of serious damage, Endurablend Systems can extend service life and defer more expensive remedies.

New products, which include Endurablend Deckset, Endurablend Crackfill and Endurablend Preserve, have been newly formulated to combat common surfacing problems experienced by roadway, airport and bridge deck pavements and to enhance crack filling and color surfacing applications.

“Industry consensus finds that every dollar invested in pavement preservation yields six to 10 times that value in extended service life,” said Nicholas Reck, director of technology — Pavements with Tensar. “This concept is also true for maintenance and rehabilitation using new Tensar Endurablend products. Pavement surfacing solutions like Endurablend Systems minimize traffic disruption, restore surface quality and optimize pavement performance at the lowest possible cost.”

Endurablend Preserve
New Jersey-based Statewide Striping Corp. recently covered worn asphalt crosswalks with a terra cotta-tinted Endurablend Preserve surfacing for a public school in Jersey City.

“The asphalt walks featured only border striping prior to treatment,” said Bob Wilson, CFO of Statewide Striping Corp. “The installations took place in late fall 2010. The area was salted and plowed numerous times over that winter, with the crosswalks remaining intact.”

Endurablend Preserve is applied cold to provide a safe and quick installation and is also highly flowable to ensure ease of penetration into cracks, voids and surface irregularities. The surfacing offers abrasion resistance to traffic, protects the substrate from exposure to fuels due to its low air voids, is effectively resistant to freeze/thaw cycles and resistant to de-icing salts.

Its 1/8th inch application is thermally compatible with asphalt and concrete, ensuring short and long-term bond with the substrate in the event of extreme thermal activity – unlike epoxies or thermal plastics.
