OLEXOBIT® SAM

OLEXOBIT® SAM is designed for use in sprayed seal to achieve excellent long-term aggregate retention under high traffic-induced stress, to improve the resistance to reflection cracking where there is a slow to medium rate of crack movement and as a holding treatment on low to medium traffic roads.

PDF-Download-or-print.pngKey Benefits

Performance Benefits

  • Superior early life adhesion
  • Excellent long-term aggregate retention
  • Improved resistance to reflection cracking

Application Benefits

  • Less loose stone during construction reduces the need to broom
  • Lower application rates than alternative PMBs
  • Easy and safe to handle
  • Low fuming compared to SBS PMBs – no more fumes than conventional Class 170
  • Compatible with conventional spray equipment and cutters
  • Excellent storage and travel stability

Application

OLEXOBIT® SAM is recommended for use where typical field conditions include:

  • Heavy traffic loading (> 500 HV/lane/day)
  • Steep grades (> 5%)
  • Tight curves (< 50m radius)
  • Intersections, T-junctions and heavy traffic entrances involving severe degrees of braking, acceleration or turning motions
  • Cracks with widths of > 2mm* and slow rate of crack movement

For further advice on the appropriate application of OLEXOBIT® SAM, please contact Puma Bitumen. *Where large cracks are present and crack movement is > 0.5mm, a PMB alone will not provide a long-term solution and should be used in conjunction with a geotextile.

Specification

OLEXOBIT® SAM is manufactured to comply with Austroads AG:PT/T190 S35E 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 - 160°C
  • Storage for up to 4 days - 170°C
  • Storage for up to 24 hours - 180°C
  • Maximum temperature - 190°C

Application Temperature Recommendations

  • Minimum pumping temperature - 150°C
  • Temperature for spraying - 180°C - 190°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.
