Samples from high-quality wearing course asphalt mixes were collected during production in the seasons 2009-2013. The samples included modified asphalts as well as reference mixes. Three different surface wear tests, with respect to abrasion from studded tyres, were carried out using VTIs circular road simulator (PVM). In order to verify the correlation between the three different test modes, tests according to EN 12697-16, Prall method, have been carried out.

Each of the tests included 14 mix types, including a reference mix, distributed over 28 test plates. The test plates were constructed in a laboratory environment. Extra plates were also constructed for laboratory testing. In total, 42 plates were required per test. Standard plates for PVM testing were used and had a thickness of about 40 millimetres.

Each test used tyres that had been “run-in” for about 500 kilometres. Sixteen tyres (including 4 reserve) were required for the test runs. Tyres were purchased at the same time from the same manufacturer and divided up randomly.

Testing was carried out until a constant linear rate of surface wear was achieved. The minimum and maximum number of machine revolutions were set at 200 000 and 300 000 respectively. Surface wear measurements were made by a laser profilometer and were taken at regular intervals on all 28 sample plates.
