Scope

This European Standard specifies a test method for determining the particle loss of porous asphalt mixtures. Particle loss is assessed by the loss of mass of porous asphalt samples after turns in the Los Angeles machine. This test enables the estimation of the abrasion resistance of porous asphalt. The test applies to laboratory compacted cylindrical specimens of porous asphalt mixtures, the upper sieve size of which does not exceed 22,4 mm. It does not reflect the abrasive effect by studded tyres.

Purpose

The purpose for revision is

- to amend and correct the terminology for requirement on apparatus;

- to introduce missing clauses and restructuring of the document accordingly;

- introduction of Annex A (Informative) on the effect of water on particle loss of porous asphalt specimens.
