• Số trang / Page: 11

Phạm vi áp dụng / Scope of standard

This method applies to bituminous sealants used in the construction and maintenance of roadways.

The method is used to determine the bituminous sealant flexural stiffness. It can be used on unaged material or on material aged using TP 86. The test apparatus is designed for testing within the temperature range from -4° to -40°C.

The values stated in SI units are to be regarded as the standard.

This standard covers the determination of flexural stiffness in bituminous sealants using the bending beam rheometer and by conducting the creep test.
