Static and dynamic mechanical properties of cement-asphalt composites with various contents of asphalt incorporated were studied. Uniaxial compressive stress-strain curves of different cement-asphalt mortars (CAMs) with cement mass ratio (A/C) in the range of 0.2 to 1.0 were obtained by the Materials Testing System (MTS) under different testing temperatures ranging from −40 to 80°C. Two typical CAMs, one with A/C of 0.2 denoted by LAC and the other with A/C of 0.9 denoted by HAC, were chosen to be tested at varied deformation rates over a range of 0.3 to 30 mm/min at room temperature. The correlation between mechanical properties, e.g., peak stress or elastic modulus, and temperature or loading rate was, respectively, acquired. As a result, temperature sensitivity and loading rate dependence for mechanical behavior of different CAMs were analyzed. Dynamic mechanical analysis (DMA) on three cement-asphalt binders (CABs) with A/Cs from 0.2 to 1.0 was carried out, and temperature spectra and frequenc...
