The applicability of this European Standard is described in the product standards for bituminous mixtures. The test is applicable to laboratory-made specimens, trimmed by sawing, o

12、r specimens from cores cut from the road, trimmed by sawing. 2 Apparatus 2.1 Calliper gauge. 2.2 Approved jig or other device. 3 Procedure NOTE The measurements should preferably be made with the specimen standing firmly on its upper face in a vertical position. Alternatively the specimen can be lai

13、d on a level surface in a horizontal position and rolled as necessary to permit the taking of all measurements. 3.1 Measurement of height 3.1.1 Take four measurements evenly spaced around the perimeter of each specimen. The position of these measurements shall be clearly marked along each specimen.
