What is BS EN 12697-16 - Abrasion by studded tyres about?
BS EN 12697-16 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. BS EN 12697-16 is applicable to bituminous mixtures with aggregate with upper sieve size not exceeding 22 mm. Provided tests in BS EN 12697-16 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 infield 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.
Who is BS EN 12697-16 - Abrasion by studded tyres for?
BS EN 12697-16 on abrasion by studded tyres is useful for:
- Manufacturers and suppliers of bituminous mixtures and asphalt
- Suppliers of construction materials
- Construction and civil engineers
- Contractors
- Road maintenance authorities
- National, international road and transport research institutes
Why should you use BS EN 12697-16 - Abrasion by studded tyres?
Bituminous materials are employed in a variety of applications, including road construction, roofing, waterproofing, and more. Particle loss of asphalt mix from pavement surfacing leads to surface distress described as ravelling which in turn affects pavement performance.
BS EN 12697-16 which helps you in delivering more durable and long-lasting products and services, that could ultimately reduce maintenance requirements by determining the susceptibility of abrasion by studded tyres.
