The CRT-WTEN1 and CRT-WTEN2 are supplied with a UKAS
certificate of accreditation validating conformance to EN
Wheel tracking is used to assess the resistance to rutting of asphaltic materials under conditions which simulate the effect of traffic. A loaded wheel tracks a sample under specified conditions of load, speed and temperature while the development of the rut is monitored continuously during the test. Test specimens can be either slabs prepared with a laboratory compactor or 200mm Ø cores cut from the highway.
The CRT-WTEN1 wheel tracker performs both procedures A and B specified for the small scale device in EN
12697-22. Procedure A requires that six specimens are tested. For procedure B only two specimens need to be tested, but rut depth must be measured at more points along the longitudinal rut profile. To speed up the testing process the CRT-WTEN2 was designed to test two specimens simultaneously.
