SURFACE FRICTION TESTERS IN ROAD BUILDING AND MAINTENANCE
ASFT friction testers are also used in road building and maintenance.
There are a few types of road friction testers, mounted mainly on Volkswagen Sharan cars. The difference between them and ASFT’s airport friction testers is in the measuring wheel used.
Construction and design of airport and road friction testers are the same. All self-propelled and trailer testers can be equipped with self-watering system and tanks of sizes tailored to the user’s needs.
In road construction, also the pulled surface friction testers may be used, in the form of T-5 (220 kg) and T-10 (420 kg) trailers.
Both types of testers are characterized by a unique system using the rear axle, consisting of a single tube and providing pressure of the measuring wheel to the road bed with a value of 140 kg.
The type of surface friction testers that are innovative and extremely useful are portable T2GO testers, weighing approx. 21 kg. They are easy to use, and can be used at almost any, even the least accessible, place, and measurements made are accurate and repeatable.
In 2010, comparative studies of T2GO and SRT-3 were conducted, which confirmed the good correlation of both devices. The research was carried out by the General Directorate for National Roads and Motorways and Research Institute of Roads and Bridges.
In 2009, Poland’s first T2GO device was purchased by the General Directorate for National Roads and Motorways (GDDKiA). Currently, both GDDKiA laboratories and universities are among the device’s users.
