OKABit-6545

Introduction:

OKABit-6545 is a versatile product with enhanced properties, especially formulated to be used as asphalt modifier for wearing and binder course applications under severe weather and traffic conditions. OKABit-6545 is an engineered alternative to Polymer Modified Bitumen (PMB) currently produced by expensive blending plants for paving applications. SBS is digested and completely dissolved in the OKABit-6545 matrix, reducing the time and equipment needed to prepare polymer modified asphalts. OKABit-6545 granules are ready to be used in asphalt plants, introducing them into the pugmill or asphalt mixer to produce high performance polymer modified asphalt mixes. It is ideal for small to large-scale paving projects.

Industry :

Asphalt Industry

Application :

- Pavement Layers: wearing and binder course, SAMI layer

- Mix Types: Asphalt Concrete (HMA), Stone Mastic Asphalt (SMA), Open Graded Friction Course (OGFC), Porous Asphalt, Thin and UltraThin Layer Asphalts

- Areas of Use: heavily trafficked highways, airports, parking areas,

ports, bridges, Industrial roads, large slopes and roundabouts. It is ideal for small to large-scale paving projects

Advantages:

* No refinery dependency – you produce modified asphalt on demand, at your plant.

* No storage instability – wet-process PMB is prone to phase separation during transport

and storage; dry addition eliminates this risk entirely.

* Full quality control – you know exactly how much polymer is added in every batch.

* Simpler logistics – no heated storage tanks, no high-shear mills, no minimum order constraints.

* Long shelf life – the granules store stably in bags or silos without caking.

* Increased softening point and elastic recovery of bitumen

* Lower susceptibility of asphalt to daily temperature variations

* Reduced thermal and fatigue cracking of asphalt

* High rutting resistance at elevated temperatures

* Moisture resistance with increased bitumen adhesion

* No bitumen oxidation during PMB production at blending plant

* No long-term storage stability problem of PMBs

* Easy usage of OKABit-6545 in the asphalt plant

* No need for expensive PMB plants and heated tanks

* Less time and energy needed in PMB blending plants

* High compatibility with any local bitumen

* High flexibility of polymer dosage, 3-6% SBS is possible on-site

* Possibility of producing polymer modified asphalt for small projects"
