Asphalt 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® 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 asphalt 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
- Greater level of compaction
- Ability to pave at lower temperatures
- Decreased binder aging
- Sites are able to reopen to traffic much earlier.
Existing asphalt designs can be used without changing any physical properties of the asphalt produced, as well as achieving other benefits e.g., lower viscosity, less air voids.
