Carboncor Infrastructure
Carboncor Repair & Maintenances
Carboncor Repair and Maintenance is used for patching and to repair potholes. The key patented process involves the mixing of carbonaceous shale with our specially formulated concentrate which, through a combination of chemically activated carbons, allows for a superior bonding strength that effectively 'binds' the aggregates tightly together to produce a strong, trafficable, long lasting and skid resistant waterproof surface.

The product can be mixed on site, with local aggregates, or it can be supplied ready made.

  • No heat is required to prepare the product or to apply it.

  • Does not require a conventional primer or tack coat before application.

  • Water is used as a primer.

  • Does not bleed in hot weather as can typical asphalt.

  • There is no lateral movement.

  • Is not sensitive to climatic conditions; successful installations were carried out at temperatures well below freezing as well as temperatures above 50 degrees Celsius.

  • Traffic may be accommodated immediately after compaction, but for very high traffic flow and heavier loads, or at intersections open to traffic after 1 - 2 hours, depending on weather or wetness of mix.

  • Exceptional binding properties. It binds to existing asphalt or any surface surrounding pothole.

  • 25% more volume or surface coverage per ton is achieved as compared to conventional premix due to the lighter kg per m3 of the product.

  • There is zero wastage.

  • The product is non-hazardous and environmentally friendly.
  • Prepare pothole by squaring it off using a pick and a spade.
  • Eradicate all grasses and weeds chemically; remove all stones and loose debris.
  • If pothole is deeper than 30mm then, preferable fill with crusher run or equivalent, leaving a maximum of 30mm in depth to reduce costs and material usage.
  • Use a small bomag, hand or vibrating stamper to compact the base well.
  • Surface should have no loose material.
  • Slightly dampen surface and edges of pothole.
  • Empty contents of Carbon Asphalt Repair and Maintenance into the pothole and work through with a rake.
  • Be certain that the material is spread evenly to ensure a smooth, level finish.
  • Allow for about 20mm of material to overlap edges of pothole and a thickness of 5mm to 10mm above the surface of the surrounding road.
  • Sprinkle with a little water using a watering can and compact with a hand stamper, or a pedestrian roller (keep wheels wet during use). The combination of water and compaction brings the fines to the surface to completely seal the pothole.
  • Pothole may be opened to traffic immediately. If the product is applied at intersections or where vehicles are turning, allow 1-2 hours to set.
  • If crusher run is not available our Asphalt may be used to fill the entire hole by applying it at a maximum of 40mm compacted to 30mm at a time. The next layer of Asphalt is then applied accordingly. The procedure remains the same. If the entire pothole is filled all at once and the pothole depresses, simply top up the pothole after a 24 hour period. Alternatively, deep potholes should be filled 15mm to 20mm above the surface of the surrounding road in order to prevent it from depressing.

Texture Tacky when wet
Colour Black
Storage life 12 months (sealed), 2 weeks (opened, but covered)
Environmental Statistic Environmentally friendly, Non-hazardous
One 25kg bag will yield +/-1m2@ a compacted thickness of 15mm.

When fresh, Carboncor Repair and Maintenance can be removed from equipment, tools and hands, with water; otherwise they should be cleaned with a solvent as for ordinary bitumen.

Carboncor Repair and Maintenance is available in 25kg bags or in bulk, ready for application in potholes or for patching and repair work. Carboncor Repair and Maintenance can also be mixed on site where volume is required.

Product can be stored for up to 12 months if stored in a cool place. If opened, it is reusable for up to 14 days so long as the unused material is covered and then remixed before application, adding a little water to reactivate the concentrate, ensure no exposure to direct sunlight. If excess product is resealed within a few hours after use, it is again reusable for up to 12 months. Therefore there is no wastage.
