High strength medium and low temperature asphalt

Low carbon asphalt


· Low-carbon Asphalt is a energy-saving ashpalt pavement method which is produced and constructed about 40~60℃(110±10℃) lower than the existing hot mix asphalt.


· High strength and medium-low temperature asphalt pavement method that improves the mechanical and construction properties of asphalt mixtures by applying a medium-low temperature asphalt modifier(Zero-M)

Low carbon asphalt application

  • Roads with heavy vehicles
  • Industrial areas
  • Highways and motorways
  • Bridges, overpasses and underpasses 
  • Residential areas
  • Densely populated areas

Low carbon asphalt modifier (Zero-M)

  • Zero-M is used as an medium-low temperature asphalt modifier for low carbon asphalt.
  • Zero-M is an eco-friendly additive for the properties of medium-low temperature asphalt modifiers and the removal of odors from asphalt mixtures during production and construction of asphalt mixtures.

Properties of Zero-M

Styrene-Butadiene-StyreneAdhesive additives
  • Improved binder PG
  • Increased softening points 
  • and penetration
  • Increased elongation and 
  • tensile strength
  • Increased cold crack resistance
  • Ductile properties
  • Improvement of adhesive properties

Construction

  • Application of the same construction equipment and construction method as for general asphalt pavement
  • The paving temperature of the asphalt mixture is 110±10°C and the compaction temperature(macadam) is 100±10°C
  • Opening to traffic is carried out when the surface temperature is below 40℃
