Application

Processing of the walls of the chambers of expansion joints of asphalt concrete and cement concrete pavements of airfields and highways, as well as structural elements of expansion joints of the bridge deck before sealing with bitumen-polymer mastics.

Advantages

  • High quality adhesive contact of the sealing bitumen-polymer mastic with the walls of the chambers of expansion joints.
  • Reliable strengthening of the surface and filling the pores of the base.
  • Increased sealing time of the expansion joint.
  • Simple unified application technology.

Composition

Composition of polymeric materials in an organic solvent (STO 77310225.007-2015).

Specifications

Mass fraction of non-volatile substances, %, not less than: 35
Density at (+20 ± 0.5) ºС, g/cm3: 0.9±0.05
Adhesion strength with asphalt concrete and cement concrete base, MPa, not less than: 4
Adhesion strength with bitumen-polymer mastic, MPa, not less than: 0.5
Drying time to degree 3 at (+20 ± 0.5) ºС, h, not more than: 0.3

Technology

  • Processing of the walls of the chambers of expansion joints with a polymer primer "Brit" is carried out using a spray gun. The primer must completely cover the surface of the walls of the joint chamber without the formation of puddles.
  • The joint is filled with bitumen-polymer mastic after the polymer primer has completely dried.

Package

Plastic canister 30 kg.
