Longitudinal Joint Sealant (LJS), or Void Reducing Asphalt Membrane (VRAM) is a product applied before paving using a distributor truck with a patented parallel spray bar to mitigate HMA voids and other longitudinal joint issues. This process is a long-lasting longitudinal joint solution complete with non-tracking rapid cure times so as to not slow down paving projects. Call Henderson Construction Fabrics for more details.
