Abstract To study the regular properties of modified bio-asphalt, analytical and measuring methods, including softening point, penetration, and ductility tests, were employed to analyze the improvement of properties in different mixing proportions of bio-asphalt and modified asphalt. Results indicated that after mixing bio-asphalt with modified asphalt, the penetration of bio-asphalt declined constantly with an increment proportional to the modified asphalt. The excellent performance at high temperature of the two kinds of bio-asphalts was affected by the mixing of modified asphalt. According to the analysis of temperature stability, the ductility of bio-asphalt significantly improved after mixing with modified asphalt, although the softening point declined. The stiffness and brittleness of bio-asphalt at low temperature improved as well, particularly in SBS and SBR modified asphalts. Results improved as the proportion of modified asphalt increased.

Key words： road engineering bio-asphalt modified asphalt temperature stability consistency plasticity
