Steel bridge orthotropic deck paving has generally been a technical challenge in the field of bridge engineering due to its complexity and uniqueness. This article describes the detailed design and construction technologies of the waterproof bonding system and the asphalt pavement structure of the Pelješac Bridge. The entire pavement area of the carriageway is approximately 38,000 m2. The epoxy resin waterproof bonding system was applied in this bridge, which was approved and certified by the German ZTV-ING series specifications. It is divided into the base layer, adhesion layer made of reactive resins, and sticky layer. The asphalt pavement comprises two layers: protective and wearing. The protective layer is 4cm-thick mastic asphalt MA11 (German: Gussasphalt) with the polymer modified bitumen PMB 25/55-55A, while the wearing layer is 4cm-thick asphalt concrete AC11 with the PMB 45/85-65. The contractor, China Road and Bridge Corporation (CRBC) researched and designed the details of the bridge's waterproof bonding system and pavement structure in two years in advance to ensure that the waterproof bonding system and pavement structure can not only match the steel deck structure properly but also provide long-term stable performance in Mediterranean climate condition of high humidity, high salt content, and changeable weather. The contractor overcame the unfavorable objective conditions such as the difficulties in organizing special engineering equipment for paving, special bitumen materials, and special process operators required for paving. The deck pavement was accomplished within five months while maintaining a high level of quality. The acquired experience and exploration should be considered as a guideline for similar mega sea-crossing bridge steel orthotropic deck pavement projects in the future.
