Influence of nanoparticles on age-associated mechanical properties of cement asphalt mortar

The early-age mechanical properties of cement asphalt mortar (CAM) directly influence the process and quality of non-ballasted track during construction. In order to shorten the long curing period of CAM during the construction of non-ballasted track and accelerate the procedure, nano-SiO2 (NS) and nano-TiO2 (NT) were added to CAM in this study; this also improved the age-related mechanical properties of CAM, especially at early ages....
