Many research on mechanistic testing have come to likely conclusion that different test setup results in different performance. The aim of this paper is to analyse the stiffness modulus resulting from three different test setups, namely; Monotonic Uniaxial Tension Test (MUTT), Monotonic Uniaxial Compression Test (MUCT), and Indirect Tensile Test (ITT). They are monotonic tests. This paper will elaborate if there is any significant difference among the result of the first three tests. Master curves of stiffness modulus as a function of strain rate at reference temperature of 15°C were developed. The results show that there is no significance difference between the modulus resulting from the three tests performed at high strain rates. It’s also shown that at low strain rate, the elastic modulus resulting from compression tests is in between indirect and uniaxial tension test’s elastic modulus.
