Abstract
The technology of guss asphalt has been introduced from Germany since 1948 and has been used widely as a paving material in steel deck of bridges. Problems due to the heavy duty traffic are occurred such as rutting, cracking, and construction technology in steep slope of the bridge as well. In the study, the guss asphalt is added with steel fiber aiming at improving the structural viscosity, and thus the resistance ability of the mixtures to rutting and cracking. In the paper, the basic physical properties and construction characteristics of the guss asphalt added with steel fiber are reported, compared with those of Trinidad Lake Asphalt.
