1. GENERAL DESCRIPTION:
Maxi-Crete® BR F20 and BR F40 is a BBA HAPAS approved material that uses a unique blend of resins, polymers, rubbers and bitumen formulated to repair cracks, spalls, holes, failed joints and most types of defects in asphalt and concrete pavements to depths in excess of 20mm.
Maxi-Crete® BR is black in colour making it highly suitable for all asphalt pavements but can also be used to repair concrete pavements when suitable coloured high PSV aggregate is used as a final surface coating.
Maxi-Crete® BR has been specially designed to extend and compress with the expansion and contraction of pavements therefore there is no need reform joints through the finished repair. Maxi-Crete®BR is approximately 20% more flexible than the standard Maxi-Crete® F40 and F20 formulation.
Due to the unique design blend, Maxi-Crete® BR produces an impervious, impact resistant, load bearing, highly flexible repair that, once installed, withstands vehicle traffic, aircraft movement and varying climatic conditions. Maxi-Crete® BR can accept vehicle and aircraft traffic within 60 minutes of application.
2. BENEFITS:
• Prolongs the life of cracked pavements
• Prevents the ingress of water and de-icing salts
• Enhances ride quality
• Simply heat and apply
• Minimal traffic disruption
• Flexible repair will not crack
• Highly resistant to plastic flow and de-icing chemicals
3. APPLICATION:
• Road and highways
• All airfield pavements
• Industrial hard standings
• Surface car parks
• Asphalt and concrete surfaces
4. INSTALLATION:
Weather Conditions: Installation of the material shall only be carried out on a surface temperature > -5ºc. Below freezing temperatures warrant extra care with preparation and when applying Dantex Crete Primer to the concrete surfaces.
5. INSTALLATION PROCEDURE:
5.1 A mixer with an agitator must be used.
5.2 Place the material carefully in the mixer. The material is heated and melted to the correct working temperature and must be kept mixing at this temperature for a minimum of 40 minutes prior to use. The molten material is then poured into the prepared repair section and levelled. The finished repair is left to cool and solidify prior to opening to traffic.
5.3 Prior to use the user must ensure that the Material Safety Data Sheet, BBA HAPAS certificate, Installation Method Statement and the Safe Systems of Work Sheets are read and followed, copies available upon request.
Dantex Crete Primer must be used with all Maxi-Crete® BR when used on concrete surfaces.
