Abstract
This paper relies on Taizhou bridge steel deck pavement substantial project in which gussaphalt is used as underlayer, and focuses on giving a reference to gussaphalt mixture deisgn for Taizhou bridge deck. The synthesis grading is determined as 2 #∶3 #∶4 # material: mine powder =30∶10∶36∶24 (mass ratio), the optimum asphalt content is 8.9%, the mixture not only has optimally high and low temperature performance but also meets the needs of design..Gussasphalt is instructed and manufacatured by this mixing proportion which is proved in construction site, has characteristics of resisting warter, anti-ageing and good suite for steel panel, it can satisfy the demands of Taizhou Bridge's actual use.
