Frequently Asked Questions
Styrelf® PMB 40 (Hyma) is a modified polymer bitumen developed using elastomeric SBS polymers and advanced cross-linking technology by TotalEnergies. It is manufactured using a high-shear process to ensure uniform polymer dispersion and strong adhesion between aggregates and binder. In road construction, it is mainly used for high-performance pavements, airport runways, flyovers, junctions, roundabouts, and roads exposed to heavy traffic and extreme temperatures.
- Styrelf® PMB 40 (Hyma) offers several performance advantages, including improved resistance to rutting and fatigue cracking, enhanced flexibility, better adhesion, and reduced oxidation. It also helps extend pavement life, improves stability under heavy loads, and can reduce pavement crust thickness by up to 20%, making it suitable for perpetual pavement applications.
- Styrelf® PMB 40 (Hyma) improves pavement durability through its viscoelastic properties, which help the pavement withstand both high and low temperature conditions. It minimizes thermal cracking, rutting, and fatigue damage caused by repeated traffic loading. The strong polymer-aggregate bonding also enhances pavement flexibility and structural stability, resulting in longer-lasting roads with lower maintenance requirements.
- Unlike conventional bitumen, Styrelf® PMB 40 (Hyma) is modified with advanced SBS elastomeric polymers that significantly improve elasticity, temperature resistance, and aging performance. Conventional bitumen may soften under high temperatures or crack under low temperatures, whereas Styrelf® PMB 40 (Hyma) maintains better performance across a wider temperature range and under heavy traffic conditions.
- Styrelf® PMB 40 (Hyma) is best suited for demanding infrastructure projects such as airport runways, highways, urban intersections, flyovers, roundabouts, industrial roads, and other high-stress pavement areas. It is particularly effective in locations experiencing extreme weather conditions and continuous heavy traffic loading.
