Abrasion Tests for Railroad Ballast | Environmental XPRT

Mechanical abrasion tests are an important basis for evaluating the suitability of rock for use as railroad ballast. This paper considers three such tests: Los Angeles abrasion, the test primarily used by North American railroads; Deval abrasion, the test primarily used by British Rail; and mill abrasion, a relatively new test being proposed for use in North America.
