PMB 40-100/50

Hot poured elastomeric joint sealant

PMB 40-100/50 is a hot poured elastomeric joint sealant designed for the treatment of reinstatements and asphalt overlays meeting the requirements of the TII Specification for Roadworks Series 900 Section 10.1.8.


PMB 40-100/50

Why Use PMB 40-100/50?

  • Effective: Specially formulated to seal the vertical faces of horizontal pavement joints.
  • Convenient: PMB 40-100/50 is supplied in 20kg siliconized, easy strip cartons. These are leak proof when kept upright.

  • Ensure the joints to be sealed are thoroughly cleaned and free from dust, fuel and oil spillage.
  • The face of the joints should be dry with surface temperature ideally at least 12°C. Do not apply to icy surfaces or in rain. (NB if joint has to be treated in damp conditions, use COLAS RS Bitukold – a pourable, cold applied edge sealant).

  • PMB 40-100/50 must be heated before use. For best results, use heating kettle with an indirect heating system such as hot oil. Ensure that H4 Polymer does not exceed 180°C and that the oil does not exceed 240°C.
  • When hot, pour either from a can or direct from the melting kettle via a pressure fed heated hose with a special nozzle.
  • Do not allow water to come into contact with the hot molten bitumen

  • For a 40mm vertical joint face, and a 2mm coated thickness of PMB 40-100/50: 0.08kg of PMB 40-100/50 seals one linear metre of joint or a 20kg pack seals 300 linear metres of joint.
  • Note: these spread rates do not include wastage or allowance for overbanding.

Keep free from frost and extremes of heat. In the summer, store cartons in a shaded area to avoid leakage. Do not stack.

PMB 40-100/50 bitumen is suitable for jointing as required in TII Specification for Roadworks Series 900 Section 10.1.8 and complies with EN 14023.
