“…Due to the comprehensive action of vehicle loads, bridge vibrations and severe weather conditions, the deformation and mechanics characteristics of steel bridge deck pavements are more complicated and abominable than those in general pavement structure, resulting in a higher requirement of deck-paving materials for the resistance to permanent deformation, fatigue and thermal cracking, moisture-induced damage and slippage (Huang, 2007;Jacobs, 1995;Lu, 2000;Nishizawa, Himeno, Uchida, Nomura, & Higashi, 2004;Park, Choi, Lee, & Hwang, 2009;Zhang, Ye, & Yuan, 2013). Extensive efforts have been made on the research of deck-paving materials for steel bridges over the last decades (Bocci, Graziani, & Canestrari, 2015;Günther, Bild, & Sedlacek, 1987;Medani, Scarpas, Kolstein, & Molenaar, 2002;Metcalf, 1967;Olard, Heritier, Loup, & Krafft, 2005;Widyatmoko, Elliott, & Read, 2005).…”

This paper describes the performance tests for a high-viscosity asphalt mixture (HVAM) mixed with a newly developed high-viscosity asphalt (HVA) used for steel bridge deck pavement. Binder test results showed that the resistance to high-temperature rutting and low-temperature cracking of the HVA increased significantly compared to that of traditional asphalt binder and styrene-butadiene-styrene (SBS)-modified asphalt binder. Then stone mastic asphalt with this HVA was designed by Marshall Method and its engineering properties were investigated, and test results showed that HVAM has better fatigue performance and resistance against damage induced by temperature and moisture than that mixed with SBSmodified asphalt. Furthermore, dynamic modulus tests were performed on the HVAM and then master curves of the dynamic modulus and phase angle were constructed based on test results, which can be used for structure design of bridge deck paving. Application results proved the applicability of the HVAM as deck-paving materials for steel bridges.

“…In the transportation industry, an asphalt mixture is often used as the pavement material of cement concrete bridge decks [1]. In recent years, with the increase in the number of heavy-duty vehicles and the normalization of overloaded and overweight vehicles, bridge deck pavement systems have become prone to water damage, such as a loose surface during use due to internal shear deformation resulting in water infiltration [2][3][4][5][6][7]. The selection of bridge deck pavement materials and a reasonable structure design significantly affects the service life and performance of bridge deck pavement systems [8].…”

To improve the structural design rationality of cement concrete bridge deck pavement systems and reduce diseases such as interlayer displacement and rutting in the early stage of bridge deck use, this paper studies the influence and law of the coupling effect of various factors of the waterproof system on the typical stress of bridge deck pavement and determines the best structure combination for the bridge deck pavement structure. A finite element model was established by using commercial software to simulate the mechanical response of different types of waterproof bonding layer, waterproof leveling layer, and impervious structure layer under different parameters. The simulation results show that when the thickness of the pavement layer was 8 cm, the maximum shear stress of the pavement layer occurred in the middle of the wearing course and the junction between layers. When the pavement layers were continuous, the maximum strain of the waterproof bonding layer with the “rubber asphalt + protective plate” structure in the transverse and longitudinal directions was the largest. When the waterproof leveling layer was cement concrete, the structure bore a large amount of stress and easily produced cracks, resulting in water damage. High-density water-based asphalt concrete with a low permeability coefficient can reduce the interlayer shear stress and effectively ensure the interlayer bonding effect. On this basis, the following bridge deck pavement structure was proposed: waterproof system + multifunctional waterproof layer + load-bearing structure layer + surface functional layer.

“…e theoretical analysis suggested that large tensile strain might be the cause of short service life. Günther et al [16] pointed out that damage-level cracks of pavements were related to the structural design of the deck and proposed minimum strength requirements for pavements. In recent years, highly developed finite element modelling software made simulation of SBDP much easier.…”

As one of the major contributors to the early failures of steel bridge deck pavements, the bonding between steel and asphalt overlay has long been a troublesome issue. In this paper, a novel composite bonding structure was introduced consisting of epoxy resin micaceous iron oxide (EMIO) primer, solvent-free epoxy resin waterproof layer, and ethylene-vinyl acetate (EVA) hot melt pellets. A series of strength tests were performed to study its mechanical properties, including pull-off strength tests, dumbbell tensile tests, lap shear tests, direct tension tests, and 45°-inclined shear tests. The results suggested that the bonding structure exhibited fair bonding strength, tensile strength, and shear strength. Anisotropic behaviour was also observed at high temperatures. For epoxy resin waterproof layer, the loss of bonding strength, tensile strength, and shear strength at 60°C was 70%, 35%, and 39%, respectively. Subsequent pavement performance-oriented tests included five-point bending tests and accelerated wheel tracking tests. The impacts of bonding on fatigue resistance and rutting propagation were studied. It was found that the proposed bonding structure could provide a durable and well-bonded interface and was thus beneficial to prolong the fatigue lives of asphalt overlay. The choice of bonding materials was found irrelevant to the ultimate rutting depth of pavements. But the bonding combination of epoxy resin waterproof and EVA pellets could delay the early-stage rutting propagation.
