New Standard from Last Update.

1. Scope

This standard prescribes the method of test for measurement of apparent viscosity of modified and unmodified bituminous binders using a rotational viscometer and a temperature controlled thermal chamber for maintaining the test temperature.

NOTES:

1. In general, standard application temperatures are reported, although the dynamic viscosity can be measured at other temperatures, if required. Similarly, viscosity is generally reported at standard rates of shear, although additionalmeasures can be taken at varying shear rates if required.

2. In this standard, the phrase “bituminous binders” represents unmodified and modified bitumen, bituminous emulsions and cutbacks
