<p>In the conventional bitumen testing scheme, the bitumen samples are examined by means of various tests (e.g. penetration, softening point with ring and ball, breaking point according to Fraass), which do not give any direct physical parameters of the bitumen or the asphalt produced with it for certain damage cases (e.g. cracks, rutting). A conclusion from these test values to the actual behaviour of the bitumen in the asphalt road is only possible through practical experience and estimation. Basically, three groups of properties have been defined for bitumen, which summarise the most important application-oriented properties: high-temperature properties (deformation behaviour), cold properties and ageing (short and long term ageing). In addition to the classical (empirical) methods, the following methods, so-called performance based requirements (germ. <strong>GVO</strong> = <strong>G</strong>ebrauchs<strong>v</strong>erhaltens<strong>o</strong>rientiert) methods, are used in Austria for testing bitumen in accordance with EU standards.</p>
