Asphalt Innovation With Duraclime™

Duraclime™ uses warm mix asphalt technology to produce asphalt mixes at reduced temperatures while incorporating higher levels of reclaimed asphalt pavement (RAP) and asphalt shingle modifier (ASM).

Low-Temperature Mixing

Mixed at lower temperatures, Duraclime™ reduces emissions, fuel consumption, smoke, and odours during the manufacturing process. This improves the comfort, safety, and environment of workers during construction operations. Residents in local communities and the travelling public notice the improved air quality near asphalt plants and paving sites.

Reduced Carbon Footprint

The use of Duraclime™ can reduce the carbon footprint of a plant by 10 to 20 percent. With widespread implementation at all asphalt plants in North America, this reduction would be equivalent to removing the emissions from 200,000 to 500,000 cars a year.

Technical Benefits
  • Reduced emissions
  • Lower consumption of fossil fuels
  • Reduced smoke and odours
  • Improved comfort, safety, and working environment
  • Improved workability
  • Extended compaction time, with more uniform compaction across the mat
  • Reduced thermal segregation
  • Proven performance in warm and cold climates
  • Ability to incorporate high levels of recycled materials
Product Performance

Duraclime™ exhibits exceptional performance characteristics, such as: 

  • Longer pavement life because the light oils stay in the binder, reducing aging hardening
  • Reduced thermal segregation
  • More uniform compaction
  • Longer compaction times.

The superior performance of Duraclime™ in North America has been demonstrated through extensive laboratory testing as well as on several in-service projects.

Enhanced Technical Specifications

The Duraclime™ production process does not affect the asphalt binder rheology or performance grade (PG) classification. Additionally, the lower mixing temperatures are a sign of reduced aging of the asphalt binder.

Asphalt pavement analyzer (APA) wheel rut testing and tensile strength ratio (TSR) moisture susceptibility testing on Duraclime™ indicates comparable performance to conventional HMA, with the TSR results showing that Duraclime has a high resistance to moisture-induced damage.
