PROLAY & Warm Mix Asphalt

ProLay comes with a variety of aggregate size options (depending on location and application) and are available either as hot mix or as Warm Mix Asphalt. Warm mix asphalt brings the following benefits:

  • Require less energy to manufacture than conventional asphalt
  • Reduced carbon emissions in the mixing and laying process (a lower carbon footprint)
  • Lower temperatures during production resulting in: reduced binder ageing; enhanced in-service life expectancy; and whole lifecycle cost benefits
  • Earlier trafficking enabling: earlier re-opening of carriageways; reduced traffic disruption; and reduced risk of early life deformation on thick lift pavements
  • Safer application
  • Gives reduced fuming throughout paving operation
