Why Mac Mix?

All metropolitan areas have a vast network of highway infrastructure with different traffic loading. They’re designed completely differently from one another, yet they all have one thing in common: they all require the same old scripted dense-graded hot mix asphalt. It’s not a bad mix, but certainly not intended for every roadway.

MAC Mix (Multi-Purpose Asphaltic Concrete) is an asphalt pavement mixture that is designed for superior performance and a longer lasting service life. Its unique design characteristics allow it to be used in a variety of different applications. It utilizes the Balanced Mix Design approach, making it rut-resistant to traffic loading yet crack-resistant to reflective and fatigue cracking.

Design Characteristics

  • Engineered UV-resistant asphalt binder modified with tire rubber
  • 15% to 25% tire rubber with a solubility rate greater than 99.0%
  • ΔTc requirement less than 6°C for crack resistance
  • Approximately 0.5% more liquid asphalt than traditional mixtures
  • Mixture based on Balanced Mix Design approach
  • RAP and/or RAS added for sustainability and cost effectiveness
  • Can be placed at thinner (3/4″ – 1 ¼”) as well as regular paving thicknesses

In summary, MAC Mix is an asphalt mixture that can be tailored to fit the customer’s specific needs.

Learn in Person

Our Lunch and Learn presentations with local municipalities allow us the opportunity for open dialogue to help educate city engineers and planners about MAC Mix and offer unique solutions to existing problems they have with their normally specified mixes. We also offer a set of specification addendums that cities can implement into future projects.
