Application Study of Gussasphalt Concrete on Pavement of Long Span Steel Deck

The performances of the gussasphalt are fine in properties,such as water protection,fatigue resistance and bonding with steel deck. It has been used in steel deck pavement for many years abroad,so a lot of experiences have been obtained. In this paper,the technology of application of gussasphalt concrete on steel deck is introduced,such as material composing design,mixture design,strength of adhesive layer,mixture materialproperties and service performances,production and spreading of gussasphalt concrete.
