Roller compactor integrated to a wheel track machine for laboratory tests on bituminous mixes

摘要

The apparatus is adapted to produce mixes of bitumen for road paving and then to test the bitumen for deforming effects generated by tyres rolling on a road. A mould containing the mix is closed by a slab C which is pressed onto the mix by discs A acting on the extensions B of the slab C. After forming the sample G the slab C is removed and a central wheel F is lowered to engage the surface of the sample.
