Styrelf® PMB

STYRELF® PMB comprises a range of elastomerically modified bitumen. It is developed to provide high performance over a range of different applications and different conditions. STYRELF® PMB meets specifications of IRC SP53:2010 having advanced properties of softening point & elastic recovery. Styrelf® PMB Bitumen is modified with elastomeric polymers using a TotalEnergies innovative cross-linking technology which gives them exceptional properties in terms of storage stability, cohesiveness, elongation capacity and resistance to aging. The Styrelf® PMB is homogenous and superior quality PMB; which enhances life of the pavement.

FAQs

Styrelf® PMB is a range of elastomerically modified polymer bitumen developed for high-performance road construction applications. It is manufactured using advanced elastomeric polymer technology that improves the strength, flexibility, and durability of pavements. Styrelf® PMB is commonly used in highways, flyovers, city roads, junctions, and heavy traffic areas to enhance overall pavement performance and longevity.

Styrelf® PMB offers several benefits, including better resistance to rutting, fatigue cracking, oxidation, and aging. It also provides improved adhesion with aggregates, enhanced elastic recovery, and superior performance under varying temperature conditions. These properties help reduce maintenance frequency and improve the lifespan of roads.

Styrelf® PMB improves pavement durability by increasing resistance to thermal cracking, rutting, and fatigue caused by heavy traffic loads and extreme weather conditions. Its viscoelastic properties provide better flexibility and cohesion, helping roads maintain structural integrity for a longer period and reducing the need for frequent repairs or overlays.

Unlike conventional bitumen, Styrelf® PMB is modified with elastomeric polymers using advanced cross-linking technology. This modification enhances storage stability, elastic recovery, elongation capacity, and resistance to aging. As a result, Styrelf® PMB delivers superior pavement performance, especially in areas exposed to high traffic and extreme climatic conditions.

The Styrelf® PMB product range includes multiple grades such as STYRELF® PMB 40, STYRELF® PMB 70, and STYRELF® PMB 40 Super. 

Benefits

  • Resistance at higher temperatures surface against rutting and ambient temperatures against fatigue.
  • Higher resistance at low temperatures against thermal cracking because of viscoelastic nature.
  • Better stripping resistance and ITSR (Indirect Tensile Strength Ratios).
  • Better resistance against aging and oxidation.
  • Proven record of longer life of pavement.
  • Saves natural resources and reduced pollution levels by deferring the frequency of overlays and period maintenance.
  • Suitable as per Indian geography of moderate to extreme temperatures with lower susceptibility to temperature variation.
  • For national/ state highway/ city roads/ flyovers/ roundabout etc. with overall improved mix performance.
