Experimental Study on Durable Asphalt Mixture for Bridge Deck Pavement

The main disease manifestations of bridge deck pavement are fatigue cracks and rutting deformation. This paper compares and analyzes the performance of traditional asphalt mixture, styrene butadiene styrene (SBS) modified asphalt mixture, epoxy resin (EP) modified asphalt mixture and high durability asphalt mixture (HDAM) applied to bridge deck pavement through laboratory tests. The results show that the fatigue life of EP modified asphalt mixture and HDAM is about 2.3 times and 3.4 times that of matrix asphalt mixture. EP modified asphalt mixture has better high temperature stability, and HDAM has higher low temperature resistance and water damage resistance. It can be used for reference in different service areas.
