This project tested eight commonly used mixtures in Switzerland: three surface courses, three binder courses and two base courses. Three types of test methods for stiffness modulus EN 12697–26 and fatigue resistance EN 12697-24 were used: Namely, four Point Bending with prismatic sample (4PB-PR), Indirect Tensile test on cylindrical samples with pulse load form (IT-CY) and cyclic load form (CIT-CY). A total of 303 prismatic and cylindrical samples were prepared and tested. It was shown that the test procedures do not deliver the same results, both in terms of value and ranking. This is on the one hand due to the loading mechanisms and on the other due to the type testing parameters of temperature and frequency defined in the European standards. Regarding stiffness, the trend and ranking of the materials for two of the three methods (4PB-PR and CIT-CY) are similar for a majority of tested mixtures, regardless of the temperatures and frequencies used. IT-CY tests performed on eight mixtures did not show sensitivity to the mixture type as much as the 4PB-PR and CIT-CY tests that use a sinusoidal continuous force application. The fatigue resistance data show that the ranking of the two types of tests (4PB-PR and CIT-CY) for the eight mixtures tested was not the same. 4PB-PR tests induce bending and therefore are a more realistic indication of fatigue induced in the samples.

该项目在瑞士测试了八种常用混合物：三种表面层、三种粘合剂层和两种基础层。使用了三种刚度模量 EN 12697-26 和抗疲劳性 EN 12697-24 的测试方法：即棱柱形样品的四点弯曲 (4PB-PR)，脉冲载荷形式的圆柱形样品的间接拉伸测试 (IT-CY ) 和循环载荷形式 (CIT-CY)。共制备和测试了 303 个棱柱形和圆柱形样品。结果表明，测试程序在价值和排名方面都没有提供相同的结果。这一方面是由于加载机制，另一方面是由于欧洲标准中定义的温度和频率的型式测试参数。关于刚度，三种方法中的两种方法（4PB-PR 和 CIT-CY）的材料趋势和排名对于大多数测试混合物是相似的，无论使用的温度和频率如何。对八种混合物进行的 IT-CY 测试对混合物类型的敏感性不如使用正弦连续力应用的 4PB-PR 和 CIT-CY 测试。疲劳抗力数据显示，对于所测试的八种混合物，两种类型的测试（4PB-PR 和 CIT-CY）的排名并不相同。4PB-PR 测试会引起弯曲，因此是样品中引起的疲劳的更真实的指示。对八种混合物进行的 IT-CY 测试对混合物类型的敏感性不如使用正弦连续力应用的 4PB-PR 和 CIT-CY 测试。疲劳抗力数据显示，对于所测试的八种混合物，两种类型的测试（4PB-PR 和 CIT-CY）的排名并不相同。4PB-PR 测试会引起弯曲，因此是样品中引起的疲劳的更真实的指示。对八种混合物进行的 IT-CY 测试对混合物类型的敏感性不如使用正弦连续力应用的 4PB-PR 和 CIT-CY 测试。疲劳抗力数据显示，对于所测试的八种混合物，两种类型的测试（4PB-PR 和 CIT-CY）的排名并不相同。4PB-PR 测试会引起弯曲，因此是样品中引起的疲劳的更真实的指示。
