• Số trang / Page: 11

Phạm vi áp dụng / Scope of standard

This method applies to hot-poured asphalt crack sealant used in the construction and maintenance of roadways as specified by MP 25 and PP 85.

The method is used to determine the hot-poured asphalt crack sealant flexural stiffness. It can be used on unaged material or on material aged using T 367. 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 hot-poured asphalt crack sealant using the bending beam rheometer and by conducting the creep test.
