OLEXOBIT® A35P
OLEXOBIT® A35P is a polymer modified binder (PMB) that is designed for use in dense-graded asphalt where increased asphalt modulus is required to enhance pavement stiffness, or to provide resistance to high surface shear forces.
Key Benefits
Performance Benefits
- Increased modulus and strength
- Increased shear resistance
Application Benefits
- Excellent workability
Application
OLEXOBIT® A35P is recommended for use:
- In high modulus asphalt
- Where asphalt is subjected to high surface shear forces, such as race tracks
For further advice on the appropriate application of OLEXOBIT® A35P, please contact Puma Bitumen.
Specification
OLEXOBIT® A35P is manufactured to comply with Austroads AG:PT/T190 A35P grade.

Storage & Handling
The storage of bituminous binders for prolonged periods at elevated temperatures should be avoided as quality may be adversely affected. As a general rule, bituminous binders should be stored at the lowest temperature that enables practical use.
Maximum Storage Temperature Recommendations
- Storage for up to 90 days 120°C
- Storage for up to 7 days 150°C
- Storage for up to 4 days 170°C
- Storage for up to 24 hours 180°C
- Maximum storage temperature 190°C
Application Temperature Recommendations
- Maximum pumping temperature 150°C
- Asphalt mixing 160°C - 175°C
- Asphalt compaction 150°C - 165°C
Health & Safety
To ensure hot bitumen is used in a safe and efficient manner the following safety precautions must be followed:
- Wear suitable personal protective equipment (PPE) at all times. Full skin protection is required to avoid accidental burns when transferring or handling hot bitumen.
- Always prevent contact between water and hot bitumen by checking the contents of the previous load before loading bituminous products into tankers and by following procedures to avoid violent boil-over of tanks.
- Avoid exposure to fumes by standing back on the gantry or upwind until the vapours have dispersed.
- Minimise bitumen fume by heating bitumen and asphalt products to the recommended temperatures.
- Minimise the use of diesel when cleaning equipment as this contributes to the bitumen fume.
For a full description of hazards associated with the use of bituminous binders, please refer to the appropriate material safety data sheet (MSDS) available on the Puma Bitumen website.
