BS EN 12697-23Bituminous mixtures. Test methods. Determination of the indirect tensile strength of bituminous specimens
This standard specifies a test method for determining the (splitting) indirect tensile strength of cylindrical specimens of bituminous mixtures.
The cylindrical specimen to be tested is brought to the specified test temperature, placed in the compression testing machine between the loading strips, and loaded diametrically along the direction of the cylinder axis with a constant speed of displacement until it breaks. The indirect tensile strength is the maximum tensile stress calculated from the peak load applied at break and the dimensions of the specimen.
Before conducting BS EN 12697-23, it is important to read the entire specification. Standards can be obtained from appropriate standard authorities.
