What Is the Digital Los Angles Abrasion Testing Machine Used For?
The Los Angeles method breaks down a graded aggregate sample by tumbling it with steel balls in a rotating drum, and the proportion of fine material produced shows how resistant the aggregate is to fragmentation and wear. The operator locks the drum with the interlock while loading the sample and charge, enters the number of revolutions on the control unit and starts the run; the counter halts the drum automatically at the set count, after which the material is sieved and the loss worked out. The standards listed are EN 1097-2, EN 12697-17 and EN 13450, ASTM C131 and C535, and AASHTO T96.

Frequently Asked Questions
What are the drum dimensions?
The rolled steel drum has an inside diameter of 711 mm and an internal length of 508 mm, and it is rotated at 31-33 r.p.m. during a test.
Does the machine stop on its own at the end of a test?
Yes. The automatic counter is set to the required number of revolutions before the run, and the machine stops automatically when that preset count is reached.
How is the drum held still for loading?
An interlock device on the drum allows the operator to lock it into position, so the drum stays in place while the sample is charged or emptied.
Is an internal shelf included?
Yes, the machine is provided with an internal shelf inside the drum, which picks up the sample and charge as the drum turns and drops them on each revolution.
Which standards are listed for it?
The standards listed are EN 1097-2, EN 12697-17 and EN 13450, ASTM C131 and C535, and AASHTO T96, covering European, ASTM and AASHTO procedures.
What does the test result show?
The loss in mass after tumbling, expressed as a percentage of the original sample, shows how resistant the aggregate is to fragmentation; a lower figure indicates a harder-wearing aggregate.
