The Los Angeles Abrasion Assay is the method for determining the surface wear resistance of aggregate grains when subjected to friction, with the objective of measuring the ability of the aggregate not to break, disintegrate and disintegrate under the effect of traffic.

In this test, the aggregate is placed inside a cylinder and through contact with a varied number of steel balls and number of revolutions (turn), where the sample enters with a defined granulometry and after friction, the sieving is done again. to measure wear.

Stratura Asfaltos is a pioneer in high-performance asphalt mixture technology and also in the structural and functional evaluation of pavements, and has the Los Angeles Abrasion Testing equipment to meet the demands of the road community.
