Asphaltic Mastic

Asphaltic Mastic

Structure and Properties

  • An overfilled sand, filler and bitumen mix (typically, 3:1:1)

  • Naturally dense so no compaction needed.

  • Can be poured at working temperatures.

  • Cools to form a viscous, flexible quasi-static mass.

  • Impermeable.

  • Bulk can be increased by adding up to 40% stone
    (known as Mastic Grout).

Applications

  • Component of grouted stone.

  • Component of OSA.

  • Asphalt slabs for lining above and below water.

  • Reinforcing stone revetments.

  • Bed and toe protection.
