Many specifications for coarse aggregates, that are to be used in highway construction, limit the percentage of wear when tested by AASHO T-96 "Resistance to Abrasion of Coarse Aggregate by use of the Los Angeles Machine". This test consists of placing a 5000 gram sample of the aggregate in a "hollow steel cylinder, closed at both ends, having an inside diameter of 28 inches and an inside length of 20 inches. The cylinder - - - shall be mounted in such a manner that it may be rotated with the axis in a horizontal position. - A removable steel shelf, projecting radially 3-1/2 inches into the cylinder and extending its full length, shall be mounted along one element of the interior surface of the cylinder."
