To reveal the material properties and modified mechanism of Albania Rock Asphalt(ARA),the properties of ARA raw material and the pavement performances of ARA modified asphalt were analyzed through the laboratory tests on asphalt content,four-component,asphalt performance,XRD pattern,infrared spectrum and fluorescence microscopy etc.The results show that the asphalt content in ARA is over 70%,which is a kind of hard asphalt with higher content of asphaltene and resin.Its mineral composition mainly includes silicate,CaCO3,CaSO4 and small amounts of metal oxides such as Fe2O 3 and Al2O3.Blending ARA and petroleum asphalt is a kind of physical blending and modifying process,and there is a good compatibility between them.ARA can play the role of natural asphalt substances to increase viscosity and elasticity as well as minerals to increase reinforcement and toughness.This can effectively improve high temperature stability,temperature sensitivity,aging resistance,spalling resistance and construction safety of modified asphalt.Therefore,as a kind of natural asphalt modifier,ARA can be used to improve the asphalt pavement performances,and its suitable mixing amount is 10%~20%of the mass of base asphalt.However,during the application process,its asphalt content should be rapidly tested by the combustion method at 538℃.When the wet process is adopted,stirring should be strengthened to ensure the uniformity of ARA modified asphalt.
