This document specifies a procedure for the determination of the particle size distribution of the aggregates of bituminous mixtures by sieving. The test is applicable to aggregates recovered after binder extraction in accordance with EN 12697 1 or EN 12697 39. NOTE Fibres, solid (non-soluble during extraction) additives and (some) binder modifiers influence the test result.

This document specifies two test methods (method A and method B) for determining the susceptibility of abrasion by studded tyres, tested on cylindrical specimens of bituminous mixtures. The test methods are applicable to bituminous mixtures with aggregate with upper sieve size not exceeding 22 mm. The tests are applicable to laboratory produced specimens or cores drilled from a slab or pavement. NOTE 1 Method A originates from the ‘Prall’-method, which has been improved by comprehensive Nordic research work. The method correlates with abrasion in the field when using paving grade bitumen. According to Nordic experience by method A the correlation between laboratory and abrasion in field is not established when polymer modified bitumen or rubber modified bitumen, etc. is used. NOTE 2 Method B originates from Finnish experience and is suitable also when polymer modified bitumen is used. The correlation between laboratory and abrasion in field is not established when rubber is used.

This document describes the laboratory mixing of bituminous materials for the manufacture of specimens. This document specifies the reference compaction temperatures for mixing based on the grade of the binder for paving grade and hard paving grade bitumen. Annex A describes the method for manufacture of samples of asphalt mixtures using foamed bitumen. Annex B describes the method for manufacture of samples of asphalt mixtures using bitumen emulsion. Once mixed, mastic asphalt samples are prepared in accordance with Annex C.

This document specifies safety requirements for floating landing stages and floating bridges for use by passengers and crew. Requirements for facilities for supply and waste disposals are not covered by this document. This document is not applicable to: — floating landing stages for motor vehicle traffic; — floating landing stages for recreational craft and inland navigation craft that are not vessels, e.g. floating equipment; — more severe requirements for floating landing stages used for the transhipment of dangerous goods; — any gangway required between vessel and floating landing stage; — specialized floating structures which are not used for passenger traffic or the berthing of vessels; — floating landing stages and bridges with equipment for cargo handling.
