Brief: Want to know how rock wool boards provide superior thermal insulation for bridge and road construction? This video walks you through their exceptional performance in protecting infrastructure from temperature extremes, fire hazards, and chemical corrosion. You'll see real-world applications in tunnels and bridge pavements, demonstrating how these inorganic materials extend service life and enhance safety.
Related Product Features:
  • Exceptional thermal insulation protects structures from winter frost heave and summer asphalt softening.
  • Class A non-combustible material with a softening point around 700°C, ensuring critical fire safety.
  • Inorganic silicate composition provides chemical stability against acids, alkalis, and aging.
  • Sound absorption reduces traffic noise by 5-10dB in tunnel applications.
  • Lightweight with a dry density of 100-180kg/m³, reducing structural load on bridges.
  • Compressive strength of 80-150kPa resists permanent deformation from heavy traffic.
  • Acts as a moisture buffer when paired with waterproof membranes in tunnels.
  • Extends pavement service life by 2-3 years by minimizing temperature stress.
FAQs:
  • What makes rock wool boards suitable for bridge and road construction?
    Rock wool boards are ideal due to their excellent thermal insulation, which prevents frost heave in winter and asphalt softening in summer, along with fire resistance, chemical stability, and durability that extend infrastructure service life.
  • How do rock wool boards enhance fire safety in tunnels and bridges?
    As Class A non-combustible materials, rock wool boards resist fire with a softening point around 700°C, delay damage to concrete and steel during fires, and prevent fire spread, providing critical evacuation time and structural protection.
  • What are the key benefits of using rock wool boards in tunnel applications?
    In tunnels, rock wool boards offer sound absorption to reduce traffic noise by 5-10dB, act as moisture buffers with waterproof membranes to protect linings, and maintain concrete surface temperatures below cracking thresholds during fires.
  • How do rock wool boards contribute to cost-efficiency in bridge pavements?
    Their lightweight nature reduces structural load, saving on reinforcement costs, while their thermal insulation minimizes temperature stress and rutting, extending pavement life by 2-3 years and lowering long-term maintenance needs.
