BS EN 12697-23
The BS EN 12697-23:2017 is a method of test for indirect tensile strength of cylindrical specimens of bituminous mixtures and updates the 2003 version. The test specimen is of cylindrical shape and is heated to the required test temperature and set in the compression test machine between the loading strips for examination of its splitting tensile resistance. Presto's precision compression testing machines meet the requirements of BS EN 12697-23 to provide road construction laboratories and material manufacturers with consistent and standardized tensile strength testing data for the qualification of bituminous and asphalt products.
Significance
Indirect tensile strength is an important parameter for the evaluation of the bituminous pavement material response to stresses applied to the pavement, such as the ability to resist cracking and fatigue. The indirect tensile strength method used in this standard is also the method used for determination of water sensitivity of bituminous specimens in accordance with EN 12697-12 and is thus the foundation for many other pavement durability assessments. The use of accurate tensile data has a direct impact on the long-term performance and safety of pavements and is essential to pavement design, to material acceptance testing, and to quality control in road construction. This is a test method defined in BS EN 12697-23 to determine the splitting indirect tensile strength of cylindrical specimens of bituminous mixtures. It is a standard for bituminous materials and products used in road and pavement construction and is categorized as road construction materials. It covers specimen conditioning, test temperature, loading procedure, calculation, and reporting requirements. Presto Stantest's instruments provide the controlled, repeatable loading conditions this standard demands for dependable mix characterization.Scope
