Description
The Los Angeles Abrasion Machine, also called as the LA abrasion machine for short, is used to determine the abrasion and impact resistance of coarse aggregates and by means of weight loss percentage. The Los Angeles Abrasion test tests the degradation of standard gradings of aggregates subjected to abrasion and impact in a rotating steel drum. The Los Angeles abrasion test is a universal method for grading the coarse aggregates worldwide.
