BS EN 12697-20:2020 PDF Download

BS EN 12697-20:2020 is a standard that outlines the test methods for measuring the indentation of bituminous mixtures using cube or Marshall specimens. The purpose of this standard is to determine the depth of indentation in asphalt when a cylindrical indentor pin with a flat-ended base is applied to it under force. The standard is applicable to mastic asphalt and other types of asphalt with aggregates of maximum nominal size of 16 mm or less.

The test method described in this standard provides a means to assess the resistance of bituminous mixtures to indentation. This information is valuable in evaluating the performance and durability of asphalt materials. By measuring the depth of indentation, engineers and researchers can determine how well the asphalt can withstand external forces and loads. This is particularly important in applications such as road construction or pavement engineering, where the ability of the asphalt to resist deformation and maintain its structural integrity is crucial.

The standard provides detailed instructions on the testing procedure, including the preparation of the specimens, the equipment requirements, and the specific measurements to be taken. It ensures that consistent and reliable results are obtained across different laboratories and testing facilities. Compliance with this standard enables accurate and comparable assessments of bituminous mixtures, aiding in quality control, product development, and performance evaluation in the asphalt industry.
