 · Previous works. The LA abrasion test was originally developed in the 1920s to provide a quantitative method for evaluating the quality of pavement materials (Prowell et al., 2005, Kahraman and Fener, 2007).Over time, as the LA abrasion test was incorporated into various global standards, several attempts were made to investigate the relationship of the LAV to alternate methods.
