Characterizing Ballast Degradation Through Los Angeles Abrasion Test ...

Commonly, LA abrasion tests are believed to measure aggregate toughness, not hardness. Use of only the LA abrasion value may not be sufficient to predict ballast aggregate degradation characteristics in the field (6). Raymond and Diyaljee suggested additional tests to measure the hardness of aggre- gates, such as the mill abrasion test ().
