General description
General description
The test covers the procedure for testing coarse aggregates for resistance to abrasion. The machine consists of a rolled steel drum having an inside dia. of 711 mm and internal length 508 mm. The drum is rotated by a speed reducer driven by an electric motor at a speed of between 31 and 33 r.p.m. The machine is equipped with an automatic counter, which can be preset  to the required number of revolutions of the drum or  the total working time. The unit is supplied without the abrasive charge, which has to be ordered separately depending on the standard in use (see accessories).
The machine is supplied without the safety cabinet and it can be upgraded with:
  • CE compliant safety cabinet with door opening switch 
  • Noise reduction and CE compliant safety cabinet with door opening switch

Additional Information

The EN 12697-17 method (Cantabro test) concerns the determination of the particle loss (abrasion) of porous asphalt mixtures and the EN 12697-43 concerns the determination of the resistance of a bituminous mixtures or pavement to aviation fuel. Both procedures involve, within other standard laboratory tests, the abrasion in a Los Angeles tester conforming to EN 1097-2 without steel balls. Furthermore the EN 12697-17 prescribes a chamber or enclosure for the Los Angeles machine as the temperature shall remain constant with an uncertainty of 2°C.
This condition can be easily obtained by the soundproof and security cabinet 48-D0500/CB2  which is however necessary to comply with CE directive.
