RR

Trim the edges of a defect (hole) vertically and level the bottom. The defect should be in a shape of a simple geometric figure, e.g. a cuboid. The substrate under NEXLER RR, should be thoroughly cleaned of loose pavement fragments, aggregate, debris and other contaminants. Do not apply the product to frozen/frosty surfaces. Dry the substrate to bring it to an air-dry state before applying the mineral-asphalt mix. Prime the bottom and sides of the defect with NEXLER Penetrator G7 or NEXLER BITFLEX Primer.

Check the production date on the packaging before use. Bear in mind that, once the mix has been poured out of the bag, it is necessary to break down all the clumped pieces so as to obtain a homogeneous (loose) product structure.
The temperature of the mix must not be below 5°C in order to obtain the proper workability. During periods of reduced temperatures, store the product in a heated space for at least 24 hours before use.

NEXLER RR is a mix ready to be cold-applied to the cavity. Breaking down of any clumped pieces can be done with a rake. Slight movement of loose aggregate fractions during mechanical breakup is characteristic of a properly prepared mix. This phenomenon, which can be referred to as particle shifting, is desirable and indicative of a correct structure of the material.

Once applied, the product should fill the substrate defect and not detach from the created pavement. The surface of the last compacted layer should extend 1 to 3 mm above the surface level of the pavement.
The repair done using NEXLER RR mix is temporary with a durability of up to 6 months. The durability of the repair is mainly influenced by the quality of substrate preparation and the quality of compaction.

Depending on the depth of the defect, NEXLER RR should be incorporated in stages. During compaction, the thickness of a single layer decreases; therefore, the thickness of the layer before compaction should be approximately 20% greater. Thickness of a single incorporated layer after compaction should range between 2,5 and 4 cm. The maximum thickness of all layers jointly may not exceed 15 cm. If the pavement defect exceeds this depth, use a material similar in performance to the structure to be filled in at the bottom of the defect. The last incorporated layer, after compaction, should extend 1 mm to 3 mm above the surface of the existing pavement.
Depending on the size of the defects, NEXLER RR should be compacted with a vibrating plate or hand tamp until a stable layer is obtained.
The incorporated final layer of the mineral-asphalt mix should be sprinkled with sand of 0 - 2 mm grain size or crushed gravel of  2 - 4 mm grain size in order to prevent the mix from sticking to car wheels.
Vehicular traffic is permitted immediately after the pavement repair.

Before use, please read the application details in the product's Technical Data Sheet.
