Asphalt & Paving > Onyx & Axys Mastic Sealers


How can you extend the life of your pavement, combining the durability of a sealer with the frictional and environmental characteristics your roadways and parking lots need? Specialty sealants offer a fast and economical maintenance solution by returning traffic to projects within hours of the initial application. Additionally, they offer a very dark surface, providing great contrast to pavement markings.

Specialty sealants are a cost effective maintenance treatment intended to address the following issues before they become major road distressors:

  • Oxidation
  • Raveling
  • Loss of surface residue

Onyx, designed for roadways, is a mixture of asphalt emulsion, increased levels of aggregates, recycled materials, polymers and catalysts created to maximize frictional characteristics by improving micro texture on the pavement surface. Onyx is a cleaner asphalt technology that does not contain coal tar.

Axys, designed for parking lots, is a mixture of asphalt emulsion, fine aggregate, polymers and catalysts. It utilizes several formulas:

  • Axys C1 M3: for rapid dry times
  • Axys C2: for hot weather conditions
  • Axys eH: for easy handling without aggregate; for higher temperature pavements
  • Axys eC: for easy handling without aggregate; for cooler temperature pavements
