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.

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.
