This methodology quantifies the GHG emission reductions achieved by substituting a sulphur product for a proportion of the bitumen binder used in conventional hot asphalt paving.

Using a sulphur product in place of a portion of bitumen binder reduces required quantities of aggregate and bitumen, reduces fuel usage due to lowered mix production temperatures and reduces emissions from the hot mix plant stack and paving. GHG emission reductions arise, primarily, from the avoided production of a proportion of the asphalt binder used in conventional asphalt paving mix and, secondarily, from reduced consumption of fossil fuels due to lower mix production temperatures. GHG emission reductions may also arise from avoided fugitive emissions of methane associated with the handling and storage of asphalt.
