Los Angeles test

The Los Angeles test measures the combined resistance of aggregate particles to impact and to progressive wear by mutual friction.
It measures the quantity of particles smaller than 1.6 mm produced by subjecting the material to the impact of steel balls and mutual friction in the Los Angeles machine. The grading of the test material is chosen from the following size fractions:

  • 4/6.3 mm;
  • 6.3/10 mm;
  • 10/14 mm;
  • 10/25 mm;
  • 16/31.5 mm;
