Bituminous mixtures - Test methods for hot mix asphalt - Part 26: Stiffness
 N EN 12697-26

Annotation

This European Standard specifies the methods for characterising the stiffness of bituminous mixtures by alternative tests, including bending tests and direct and indirect tensile tests. The tests are performed on compacted bituminous material under a sinusoidal loading or other controlled loading, using different types of specimens and supports.

The procedure is used to rank bituminous mixtures on the basis of stiffness, as a guide to relative performance in the pavement, to obtain data for estimating the structural behaviour in the road and to judge test data according to specifications for bituminous mixtures.

As this standard does not impose a particular type of testing device the precise choice of the test conditions depends on the possibilities and the working range of the used device.

For the choice of specific test conditions, the requirements of the product standards for bituminous mixtures should be respected.

The applicability of this document is described in the product standards for bituminous mixtures.

Битумные смеси - Методы тестирования для асфальта горячей смеси - Часть 26: Жесткость

Этот европейский стандарт определяет методы для характеристики жесткости битумных смесей альтернативными тестами, включая испытания на изгиб и прямые и косвенные испытания на растяжение. Тесты выполняются на уплотненном битумном материале при синусоидальной загрузке или другой управляемой загрузке, с помощью различных типов экземпляров и поддержек.
