Under the background of the more and more mature era of green straw fiber modified asphalt mixture,corn straw was selected as raw material,corn straw fiber in line with road engineering application was prepared by mechanical crushing method,and matrix asphalt was modified with self-made corn straw fiber,and the penetration degree,softening point and ductility test were carried out to verify its compliance and compare with the application of mature road lignin fiber modified asphalt,and the results proved that the conventional performance of the two fiber modified asphalt with 3％content was similar.The results show that the viscosity of corn straw fiber modified asphalt under the same conditions is higher than that of road lignin fiber modified asphalt,which can form a more adequate coating effect on aggregates,and the elastic deformation ability is weaker than that of road lignin fiber modified asphalt,so it can be better selected for the specific construction environment when it is applied.
