Storage & Handling

The storage of bituminous binders for prolonged periods at elevated temperatures should be avoided as quality may be adversely affected. Bituminous binders should be stored at the lowest temperature that enables practical use. 

Maximum Storage Temperature Recommendations

  • Storage for up to 48 hours - 160°C - 175°C
  • Storage for up to 7 days 140°C
  • Storage for up to 14 days 140°C
  • Asphalt mixing 160°C - 175°C
  • Asphalt compaction 140°C - 160°C
