1. GENERAL DESCRIPTION:
Ultra-Band® BR is a flexible fill and overband repair system for cracks and joints in asphalt and concrete. It provides a flexible, impermeable and extremely durable repair that will prolong the service life of non-porous bituminous and concrete surfaces. Cracks and joints are treated up to a width of 50mm and the overband seal can be applied up to a width of 500mm. Inlaid on airfield runways and taxiways it effectively prevents FOD issues. Ultra-Band® BR is perfect for repairs to lane joints in asphalt surfaces.
Ultra-Band® BR is a unique, single component, hot-applied, bitumen and resin compound incorporating a mixture of fillers and aggregates. It has superior crack filling and sealing properties along with very effective adhesion. Formulated to have excellent load bearing and anti-oxidationproperties, in its molten state the material flows and penetrates deep into cracks and joints setting to a resilient finish. A curing time of less than 30 minutes means minimal disruption to road and airfield users.
2. APPLICATION:
•Roads and Highways
•All Airfield Pavements
•Industrial Hardstandings
•Surface Car Parks
3.BENEFITS:
•Prevents foreign object damage (FOD)
•No waste
•Single step process
•Highly Flexible
•Optimal Adhesion
•Seals and covers defects around repair area
•High friction wearing surface
•Apply any time of year
•Prevents ingress of water and salts
•High performance
4.INSTALLATION:
Weather Conditions: Installation shall only be carried out at a road surface temperature > 0°c.
Preparation of the Surface: All repairs must be thoroughly dried using hot compressed air before and during the installation of the material.
Any excavation in concrete must be primed with Crete-Prime. Allow the primed area to cure (approximately 15 minutes).
5.SYSTEM INSTALLATION PROCEDURE:
5.1 The material can be applied in two stages if the depth of the repair is > 20mm. Bags of Ultra-Band® BR are melted down in horizontal continuously agitated dedicated mixers with full thermostatic temperature control.
5.2 Ultra-Band® BR is then poured into the prepared recess and screeded with a suitable sized screed box, to finish flush with the adjacent surface and allowed to set.
5.3 The second application of Ultra-Band® BR can be carried out at any time after the first application has cured and is applied at an application temperature of 190°c ± 10°c. It is applied evenly over the previous application by screed box between 50mm – 500mm width as required.
5.4 Once cured, approximately 10 – 25 minutes dependent on ambient temperature, the work area should be swept and then re-opened to traffic.
