1 Scope
This European Standard describes 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 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 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.
