    Abstract

    Because the performance of gussasphalt at high temperatures is not good enough, this article developed a composite stiffening gussasphalt that combined composite strength theory with the structure characteristics of gussasphalt and analyzed the performance of the stiffening characteristics of gussasphalt. The results showed that after using reinforcement technology, the rutting resistance in 60°C increased about 150 % and the crack resistance in 50°C, 20°C, and −10°C increased about 180 %, 23 %, and 44 %, respectively. Stiffening gussasphalt composite beam fatigue frequency was significantly higher than conventional concrete. This development has a significant effect on the steel bridge deck carrying capacity and durability.
