Abstract
Gussasphalt concrete has been widely used in steel bridge deck pavement because of its high deformation. In this paper, Factors impacted on Gussasphalt mixture performance are systematic studied by four type gradation, three asphalt content. The best asphalt content was determined by fluidity tests and penetration tests. The road performance was verified by high temperature rutting test and low temperature bending test. The study shows that gradation and asphalt content have a great influence on the performance of mixture. Therefore, the gradation and asphalt content should be strictly controlled in the actual construction.
