Asphalt Mix Options that offer increased sustainability and reduced carbon output

Standard Asphalt Mixes

ASCO Asphalt includes recycled materials in all asphalt mixes – reclaimed asphalt products (RAP), Slag, Glass and MacRebur (link to Recycle, Reuse, Reduce web page) waste plastics and Pearl Global waste tyres

Warm mix asphalt

ASCO Asphalt does manufacture asphalt with a warm mix additive to reduce the viscosity (thickness) of the asphalt binder so asphalt aggregates can be mixed with the binder at lower temperatures to manufacture asphalt.

Reducing the viscosity also makes the mixture easier to lay and compact at lower temperatures.

By lowering the temperature at which the asphalt is produced:

  • Less energy is required in production
  • There are reduced emissions
  • Better compaction rates
  • Ability to pave at lower temperatures
  • Decreased binder aging
  • Roadworks sites are able to reopen much earlier.

Existing mix designs can be used without changing any physical properties of the mix and lower air voids lead.
