Scope
SCOPE This Standard sets out a method based on the accelerated aging of bitumen to determine the time required for bitumen to reach a viscosity level associated with distress in pavement surfacings.
NOTES:
1 The results of the test may be used to predict likely resistance to hardening of a bitumen in sprayed surfacings and in thin asphalt surfacings which are permeable to air.
2 The method takes too long to be used for 'day-to-day' quality control and is intended for occasional checking of quality, particularly where there has been a change in refinery crude feedstock or processing.
