“…It also possesses excellent adhesion and compliance with the steel deck (Qiu et al, 2019;Wang et al, 2019). Thus, gussasphalt concrete is suitable for deck paving, especially for long-span and medium-span steel bridges (Chen et al, 2011b;Sang Luo et al, 2018;Ke et al, 2019).…”

The advantageous thermal stability and construction workability of gussasphalt, a type of asphalt concrete, has drawn increasing attention. To prepare a type of superior gussasphalt concrete using Qingchuan rock asphalt (QRA), a modified gussasphalt binder was prepared with modifiers made up by different dose of styrene-butadiene-styrene, terpene resin, furfural extraction oil and SAW. Then, the rheological properties, microstructure, and thermal stability of gussasphalt binder were studied. The results indicated that the modifier #1 had significant effects on the other indexes but for the ductility, it was less effective in improving the low-temperature performance of the asphalt binder. The low-temperature performance of the binder with modifier #2 was superior compared with that of binder with modifier #1. The binder with 12.5% QRA and 5% modifier #2 can be regarded as an optimal collocation, which had a superior compatibility, high-temperature performance, and comprehensive temperature susceptibility.

“…Liu et al [ 8 ] studied the performance of composite-modified asphalt with Trinidad Lake Asphalt (TLA) as a waterproof material for bridge deck pavement through the shear test, pull-out test and water permeability test. Chen et al [ 9 ] put forward a three-stage characterization method of the Gussasphalt mixture. The primary characterization starts from evaluating the viscoelasticity of the binder, expands to the rheological behavior of asphalt-mineral filler cement, and finally, studies the engineering performance of the Gussasphalt mixture.…”

Epoxy asphalt concrete, mortar asphalt concrete and Gussasphalt concrete are commonly used types of deck pavement materials in bridge deck pavement engineering. However, achieving the high-temperature stability and anti-fatigue performance of the deck pavement materials is still challenging. In order to reduce the rutting and cracking risks of the asphalt mixture, this paper proposed pre-coated aggregates grouting asphalt concrete (PGAC) for bridge deck pavement. Laboratory tests were conducted to determine the optimum grouting materials and to evaluate the mechanical performances of the PGAC material. Test results showed that the mechanical properties for PGAC with grouting material of high-viscosity-modified asphalt binder blending with mineral filler were superior to that of GMA-10 used for the Hong Kong-Zhuhai-Macau Bridge deck pavement. Microstructural analysis showed that the PGAC had a more stable skeleton structure compared to other typical aggregate mixtures. This study highlights the performances of the proposed PGAC and sheds light on the deck pavement material improvement of both high-temperature stability and anti-fatigue performance that could be achieved.

“…Nowadays, no materials that would prove themselves well enough in work, both at positive and at significant negative ambient temperatures have been invented. But the use of cast asphalt concrete in the construction of a roadbed on bridge structures is able to ensure the durability of the entire structure and meet the requirements more efficiently than other types of coatings [2][3][4][5][6][7]. Cast asphalt concrete has a number of advantages such as: water resistance, high plasticity and fatigue life, while the value of the indicators increases several times when used in the composition of modified binders.…”

Over the past few years, the research of the use of cast asphalt concrete mixtures in the upper layers of the coating of bridge structures has been actively carried out. The experience gained allows us to conclude that one of the most common effective ways to improve the durability and thermal stability of cast asphalt concrete pavements is the use of modified bituminous binders. The modified bitumen part of cast asphalt concrete acts as a medium capable of initiating the «self-healing» of the composite, independently eliminating structural defects. This study aims to research the rheological characteristics of modified bituminous binders. Bitumen grade BND 50/70 was used as a raw material in the study; the following types of additives were used as its modifiers: rubber modifier (RM), EVATHERM and SBS. The optimal concentrations of the proposed additives for modification allowing to achieve the effect of structuring the mastic component of cast asphalt concrete with insignificant increases in the temperatures of mixing and compaction of mixtures based on them have been revealed.
