OXIDIZED ASPHALT

For Roofs

Description:

OXIDIZED ASPHALT is produced by air blowing of petroleum residues.

It is mixed in-place with other components like limestone aggregate, cement and hydrated lime to give a waterproofing material, solid or semi-solid under normal weather conditions. This mix produces a mastic that is waterproof.

It softens gradually when heated to 200°C, so it can be spread easily on the roofs.

OXIDIZED ASPHALT with the other components is mixed in-place to give Mastic Asphalt used in the construction of built-up roofing as waterproofing and adhesive layer.

Uses:

OXIDIZED ASPHALT with the other components is mixed in-place to give Mastic Asphalt used in the construction of built-up roofing as waterproofing and adhesive layer.

  • Type I asphalt is used for the bottom layer.
  • Type IV asphalt is used for the upper layer due to its higher softening point.

Standard:

  • Type I and Type IV asphalts comply with ASTM D 312.
  • Limestone aggregate with not less than 80% cal­cium carbonate complies with J.S 96/1982.
  • Cement complies with J.S 30/1981 or J.S 219/1981.
  • Hydrated lime complies with J.S 153/1982.

Containers:

Can be supplied in 180 kg steel drums.
