Bituminous mixtures - Test methods - Part 21: Indentation using plate specimens
Also Known As:
The DIN EN 12697-21 standard describes a test method for measuring the indentation of mastic asphalt. The test involves penetrating the asphalt with a cylindrical indentor pin with a circular flat-ended base at a specific temperature, load, and duration. This standard is applicable to mastic asphalt with aggregates that have a maximum nominal size of 16 mm or less.
The purpose of this test method is to assess the deformability and resistance of the mastic asphalt under specified conditions. By measuring the depth of indentation, it provides a means of evaluating the functional characteristics and performance of the asphalt mixture. This information is vital for determining the suitability of the material for various applications, such as road construction and maintenance.
The standard provides guidance on the testing procedure, including the preparation of the plate specimens and the selection of the appropriate indentor pin for testing. It also specifies the testing conditions, such as the temperature and load to be applied during the test. The measurement apparatus and methodology are detailed to ensure accuracy and consistency in obtaining indentation data.
