Areas of application
BORNIT® Crack Compound H is a crack sealing compound for repairing network cracks (also known as overseal banding) in asphalt and concrete pavements, and improves the grip of worn road surfaces. Product complies with TL Fug-StB 01.
Type and properties
BORNIT® Crack Compound H is a polymer bitumen-based crack repair compound with
Surface
The substrate must be solid, clean (blow out any cracks with compressed air beforehand) and free of release agents (oil, grease, dust, etc.).
Processing
Melting the casting compounds
BORNIT® Crack Compound H must be melted slowly to the processing temperature in melting kettles equipped with a stirrer and thermometer. Simple bitumen melting pots without stirrers and thermometers pose a risk of local overheating of the compound, with the result that the fillers and plastics added to stabilise and temper the products settle and/or are irreversibly destroyed.
The casting compounds must only be melted in clean cookers that are free of residues of any kind. Different types of grouting compounds must not be mixed together.
Preparation for crack sealing:
The following conditions must be met to ensure that joint/crack sealing work is carried out properly.
• Joint/crack sealing must be carried out in dry weather.
• The surface temperature of the components must be at least +5 °C.
• The area to be treated must be kept free of traffic.
Filling cracks/oversee banding
When using BORNIT® Hot Compound Primer, it must be dry (finger test).
The compound must be at the specified temperature when filling. If the processing temperature is significantly below the specified temperature, the flowability suffers and the compound does not completely fill the cracks/joints to be filled. There is then a risk of cavity formation and poorer adhesion, which results in the filled compound sagging under rolling road traffic (water penetration into the substructure). The casting work must be carried out with suitable equipment, e.g. casting pots or lances. When casting the cracks, the compound is applied generously with a pulling shoe, following the course of the crack. This allows the compound to run into the crack and fill it. The overlap on both sides prevents the compound from detaching in the flank area of the crack.
In the Overseal Banding process (surface renovation), the still-hot mixture is sprinkled with either dry or pre-coated, bituminous high-grade chippings in order to achieve the desired grip and visual match with the existing surface. Once the mixture has cooled, the unbound chippings are swept away.
Since all casting compounds shrink in volume after cooling, the casting should be carried out in two stages. Immediately after the first casting has cooled, the second casting must be carried out, whereby the work sequence must be arranged so that the second casting is applied to the still shiny, clean surface of the first casting. During the second casting, care must also be taken to ensure that the processing temperature is not exceeded in order to guarantee homogeneous fusion.
