Tests for geometrical properties of aggregates - Determination of percentage of crushed and broken surfaces in coarse aggregate particles not-eligible a gross sample representative of1 Scope This European Standard specifies a method for the determination of the percentage of particles with crushed and broken surfaces in a sample of natural coarse aggregate. It applies to gravel or mixed aggregate containing gravel. The test method specified in this part of this European Standard is applicable to particle size fractions di Di where Di 63 mm and di 4 mm. NOTE 1 For aggregate sizes with D > 63 mm and or d < 4 mm the test may be
