Abstract
The characteristic values determined with the cyclic indirect tensile test in accordance with the Technical Test Specifications TP Asphalt-StB, Part 24 "Resistance to fatigue" and Part 26 "Determination of stiffness", form the input variables for the calculated dimensioning in accordance with the RDO Asphalt 09.
Knowledge of the precision of these two test methods is thus a basic prerequisite for the use of computational dimensioning in the context of construction contracts. The aim of the research project is thus to determine the comparative and repeatability precision of the cyclic indirect tensile test within the framework of an interlaboratory test in accordance with the "Code of Practice on the Statistical Evaluation of Test Results".
