Abstract
This paper evaluates the properties of composite modified asphalt by selecting four kinds of nano-materials combined with composite modified the base bitumen with QingChuan rock asphalt.Asphalt ex-periments contain the three maj or indexes,rotational viscosity test,dynamic shear rheological test and bending beam rhememer test and rotating film drying oven test,and asphalt mixture tests include rutting test,oil immersion stability test,water immersion stability test and freeze-thaw splitting test.Compared with base bitumen and rock asphalt,the penetration and ductility of composite modified asphalt reduce while softening point increases.Nano-materials and rock asphalt can significantly improve the consistency of asphalt,high temperature performance as well as anti ageing property.But low temperature properties have adverse effects.The mixture test shows that the addition of rock asphalt and nano materials can im-prove the anti-rutting ability,anti water damage and anti erosion performance of aviation kerosene.The study shows that the composite modified asphalt meets the requirements of the technical indicators of air-port pavement.关键词
