The analysis showed that the tested melafir contained too many minerals not resistant to weathering.}, abstract={This fact had a significant impact on the exploitatnion of the new done motorway surface. The surface layer of the motorway was made between June and November 2001 and at the beginning of 2003 there started its renovation. The resulting rapid wear of the upper surface of the motorway may be explained by an excessive content of minerals that have gone rapid transformations (weathering and oxidation) in the conditions of the top surface layer of the motorway.}, type={artykuł}, title={Mineral composition of melaphyre rocks and durablity of a motorway surface = Skład mineralny skał melafirowych a trwałość autostrady}, keywords={skała melaforowa, autostrada, nawierzchnia autostrad, warstwa wierzchnia, melaphyre rocks, motorway, surface layer}, }
