Surface-EXT™

FORTA® Surface-EXT™ is an alkali and acid resistant glass fiber specifically designed to extend the life of slurry surfacing pavement applications.

Surface-EXT improves pavement flexibility and long-term durability. Surface-EXT is extremely easy to use and has a specific gravity similar to that of the aggregate, which allows it to disperse completely and evenly into the slurry mix. The glass fiber can be used at any dosage to suit the end user’s project needs. Surface-EXT does not increase the water demand of the mix and may reduce the setup and cure time of the mix thus reducing overall road closure time, all without negatively impacting workability.

Features & Benefits:

  • Alkali and acid resistant glass
  • High split efficiency
  • Excellent dispersion
  • No increase in water demand
  • Excellent workability
  • Excellent mechanical performance
  • Increases pavement flexibility
  • Mitigates reflective cracking
  • Improved long-term durability
  • Suitable for all Slurry Surfacing applications
  • Available as pre-chopped fibers for ease of use*

Applications

FORTA Surface-EXT is used in slurry seal and micro surfacing paving applications. Surface-EXT has been designed to arrange into a matrix in the mixture which helps link the asphalt to the aggregate giving the cured mixture additional durability. It assures excellent workability and reliable long-term performance. Use of Surface-EXT typically does not require a change to the mix design, but in some cases may allow a reduction in the mineral requirement for the mix.

 

* Also available as roving which can be easily chopped on-site/on-demand with special equipment available from FORTA®. If purchased as roving, the rovings are protected by a shrink-wrap polythene film, open at the top which should not be removed when the product is in use. Rovings are packed on pallets.

FIBER EXPERTS ON STAFF Ready to Answer Questions & Aid in Technical Support

FORTA® Surface-EXT™ fibers are incorporated directly into the slurry surfacing mixing system with the specially designed FORTA Ranger dispensing system. Use of the Ranger system assures trouble-free and equal dispersion of the fiber in the mix. The recommended dosage is 0.15% to .4% of the dry aggregate weight; however, other dosing amounts have been used for specific mix designs

FORTA Corporation has spent years on engineering research and conducted scores of test projects to develop our unique fiber system. Not only do we manufacture the fibers, but also have created a proven comprehensive process to ensure successful product performance.

FORTA® Surface-EXT™ fibers are supplied in convenient 40 pound bags.*
