“…SPPEA mixture showed considerably lower dynamic stability than OGFC-13, which has larger aggregate size and thus better interlocking skeleton structure [93]. However, dynamic stability EAM was slightly increased with the increase of lightweight aggregate percentage [106]. EAM prepared using the V-S design method showed slightly higher dynamic stability than conventional EAM but significantly higher dynamic stability than SMA due to its skeleton structure [97] and the thermosetting nature of EA [97,103].…”

“…Glass [104] and mineral [105] fibers have been introduced to EA for their reinforcing and toughening effects. EAM prepared with ceramsite-based lightweight aggregates was applied on bridge deck to reduce its deadweight [106]. As an approach to consume waste glasses, glass aggregates processed from sheet glasses were blended with EAM and good performance was obtained for up to 50% glass aggregates [107].…”

One of the failure mechanisms associated with asphalt paving layers, especially on steel deck bridges, is large permanent deformation, which adversely affects its long-term performance in service. Thus, epoxy resin was introduced in asphalt paving industry to tackle permanent deformation of asphalt mixtures due to its thermosetting nature. In this review, epoxy resin as a dominant component of the epoxy-asphalt composite system was first considered, followed by a discussion on its curing methods and curing mechanism. Furthermore, the physicochemical property and mechanical performance of epoxy asphalt and epoxy asphalt mixture were thoroughly examined. Crosslink density of epoxy asphalt dictates its viscosity and thus the allowable construction time. Phase separation and dispersion of asphalt particles in the epoxy matrix was observed for epoxy-asphalt composite, and it showed superior elastic behavior and deformation resistance capability when compared with conventional asphalt materials. Furthermore, epoxy asphalt mixture exhibited significantly higher compressive strength, much better rutting resistance, and superior durability and water resistance properties. However, its low-temperature cracking resistance was slightly compromised.

“…In China, SMA did not perform well as steel deck-paving material in the early projects because of the limitation of former modified asphalt technology (Chen, Huang, & Wang, 2004;Fan, 2004;Qian, Luo, & Jing, 2005). Guss asphalt and epoxy asphalt are extensively used for steel bridge deck pavements despite their disadvantages of high cost and complicated technique (Chen et al, 2004;Chen, Qian, & Hu, 2013;Fan, 2004;Huang, 2006;Qian, Chen, Jiang, & Smit, 2013). Unfortunately, various types of distresses such as rutting, pothole and cracking have been observed in many engineering projects with the latter two technologies in recent years (Li & Qian, 2006;Xu, 2014;Zhang, 2004).…”

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.

A novel ultra high performance concrete (UHPC) layer composite orthotropic steel deck was adopted in the construction of a new bridge in China to improve the fatigue performance of the orthotropic steel deck plate and reduce the disease of surface wearing layer. In situ experiments were conducted to study the UHPC layer’s impact on the behavior of the orthotropic steel deck. The test vehicle loads were applied on the deck plate before and after UHPC layer paving, the stresses where fatigue cracks usually occur and the deflections of critical sections were measured. The test results verified that the UHPC composite steel deck system could significantly reduce the stress of the rib-to-deck connection region and the stress at the bottom toe of rib-to-diaphragm weld. In addition, it slightly influenced the performance of U shape rib, girder web-to-deck and diaphragm cutout.
