In this research, the physical properties and chemical properties of AsButon were analysed, and the AsButon can be expected to be more durable than straight asphalt at high temperatures. The tendencies of the compositions of AsButon were close to the tendency of the composition ofTrinidad Lake Asphalt (TLA). Therefore the asphalt mixture tests for guss asphalt using AsButon were conducted. As the results, the guss asphalt mixture using AsButon ratio of 20% was met the Japanese standards of guss asphalt mixture for fluidity, dynamic stabilityand flexural strain. AsButon is regarded to be possible alternative for TLA as guss asphalt material for steel bridge deck pavement. |
