Polymer-modified bitumen (PMB)

SBS reinforcement for rut resistance on key routes

SBS-based polymer-modified bitumen with an optimized polymer content, delivering high thermal stability and outstanding elastic recovery. The mandatory choice for expressways, major bridges and hot, humid climates — extending pavement life and cutting maintenance costs.

Key advantages

  • Resists wheel tracking and deep rutting at high temperatures — the solution for Vietnam's hot, humid climate
  • Elastic recovery above 70%, handling repeated heavy loads far better than penetration-grade bitumen
  • Extends pavement life and significantly reduces maintenance costs over the project life cycle
  • Standards-compliant storage stability — no polymer separation during transport and heating
