Multigrade bitumen is engineered to offer superior performance across a wide temperature range, making it an ideal binder for medium to high traffic roads and areas prone to rutting and deformation. These binders combine the low-temperature flexibility of conventional bitumen with the high-temperature stiffness needed to resist heavy loads and slow-moving traffic.

Puma Bitumen supplies two key multigrade binders tailored to different applications:

• M500 – Designed for spray sealing, M500 offers enhanced cohesion and stability in high-stress sealing environments such as tight curves, turning lanes, or rising temperatures.

• M1000 – Formulated for asphalt applications, M1000 delivers increased stiffness and load resistance, particularly useful in urban arterials, freight corridors, and intersections.

Multigrade binders help reduce rutting without the need for polymer modification, offering a cost-effective and spec-compliant option for road managers looking to extend pavement life.

Benefits:

• 🚛 Improved high-temperature stiffness for rut resistance

• ❄️ Maintains flexibility at low temperatures to resist cracking

• 🛣️ Suitable for high-stress or slow-moving traffic locations

EME2 (Enrobé à Module Élevé Class 2) is a high-modulus binder specifically designed for use in deep-lift structural asphalt layers. Originating in France and now adopted in Australia under Austroads and TMR specifications, EME2 enables thinner, stronger pavements capable of handling high traffic and loading.

By significantly increasing asphalt stiffness, EME2 allows pavement thickness reductions of approximately 25–33%, delivering long-term cost savings without compromising structural integrity.

EME2 mixes are produced with a high binder content (around 6%), providing excellent rut resistance and stability. Due to their increased stiffness and brittleness, EME2 binders are used exclusively in base or sub-base layers, where tensile strains are low and fatigue is not the controlling design factor.

Key Features of EME2:

• 📏 Reduces pavement thickness by 25–33% compared to conventional asphalt

• 🔩 High modulus for superior stiffness and structural support

• 🚛 Exceptional rut resistance, ideal for heavy traffic and freight routes

• 🧱 Used only in structural layers (not surfacing) due to its brittle nature

• 🧪 Designed for high binder content (~6%) in accordance with Austroads mix design protocols

EME2 is a specialised solution for projects seeking efficient structural design, especially where long-haul traffic, freight demands, or axle loading make deformation resistance a priority.
