VOID REDUCING ASPHALT MEMBRANE 2017-12-01T20:59:07+00:00

A Void Reducing Asphalt Membrane (VRAM) is placed in the form of a heavy membrane under the intended area for an overlay construction joint, either 12” or 18” wide and with thickness up to 5/32”. The VRAM then migrates into the high air voids in the HMA overlay in the area of the longitudinal construction joint and reduces voids to more typical HMA range

The VRAM is suitable for construction traffic to drive on without pick up or tracking within 30 minutes of placement.

Features and Benefits:

During construction:

  • Upward migration
  • Non-tracking
  • Resist Flow
  • Crack resistance
  • Reduces water and air permeability
  • Bonds to existing pavement
  • Longitudinal joint issues
