The influence of loading rate on the mechanical properties of two typical cement asphalt mortars(CAMs) with varied asphalt to cement ratio(m_A/m_C) was studied.Uniaxial compressive stress-strain curves of the two CAMs were tested by the MTS(material testing system) at different displacement rates ranging from 0.3 mm/min to 30.0 mm/min.The correlation between peak strength or elastic modulus and loading rate was acquired and experimental data were fitted to the presumed mathematical formula that is proven ap...
