Report of the limited Round Robin Trial with the RCAT- BRRC synthesis E40/05

The RCAT (Rotating Cylinder Ageing Test) device was developed to simulate the long-termageing of bituminous binders in an accelerated manner. The method is a conditioning procedure and has no result in itself.

In order to collect information on the reproducibility of the procedure,a limited round robin trial with the RCAT method involving five laboratories and three binders was conducted in 2003. Tests were conducted according to the draft of the RCATmethod (prENxxxxx-RCAT) drawn up in the framework of CENcommittee TC336WG1 TG3.

During this RRT, a health and safety risks assessment was also carried out. The five participating laboratories have rated the residual risks as acceptable.
