Los Angeles Abrasion Test:

In which the aggregates are placed in a rotating drum in which a certain number of cast iron cylindrical balls are also placed, and the drum rotated at a given speed for 500-1000 revolutions. The weight of fine material that is generated is determined. A Los Angeles Abrasion value of 40 per cent is allowed for stone aggregate base courses and 30-35 per cent for bituminous courses. The apparatus is shown in Figure.
