DOI: 10.1016/j.conbuildmat.2017.04.130
Abstract: Abstract Cracking is one of the main reasons for asphalt pavement damage. Because of the anisotropism of asphalt mixtures, traditional experimental methods cannot analyze displacement and strain fields accurately. A full-field, noncontact measurement technology—the digital… read more here.
