Testing mineral aggregates of asphalt: Use of test slab method

    Research output: Chapter in Book/Report/Conference proceedingConference article in proceedingsScientific


    The Technical Research Centre of Finland (VTT) has used the test slab method since 1995 for measuring the wear resistance of asphalt surfaces. In this method test slabs are rolled in the laboratory and set into the road. Today, about 240 test slabs have been set into roads at various locations in Finland. Wear measurements of the test slabs are made with a laser profilometer. The research objectives include studying the effects of mineral aggregate quality, particle shape, maximum particle size, used crushing procedure, industrial by-products and asphalt fillers. Also, the effects of binding between aggregate and bitumen, asphalt type and asphalt proportioning on asphalt wear have been examined.
