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)
