Investigations of resilient moduli of selected hydraulically bound mixtures (HBM) under cyclic load

This paper presents the results of resilient moduli tests carried out on selected hydraulically bound mixtures (HBM). Both static and dynamic loading procedures were used. In total, thirteen hydraulically bound mixtures designed for construction of road base and subgrade improvement were tested. The mixtures were composed of crushed granite, dolomite or recycled concrete mixed with a hydraulic road binder, cement and two types of fly ash. The specimens were subjected to cyclic loading with 0.248 s and 50 s load times. Moreover, the specimens were subjected to compressive and tensile strength tests. The tests showed that the load duration had no significant effect on the obtained resilient modulus. This resulted from good linear correlation between the values obtained with the two load times, namely 0.248 s and 50 s. Non-linear relationships were established between the values of compressive and tensile strength and the resilient modulus. Some differences were noted in the shape of curves drawn for the respective granular materials and binders. This indicates that some physical ingredients may have an impact on the above-mentioned relationships.
