Abstract: For long-span steel bridge structures, deck paving is a key technology because it has a significant impact on bridge durability, driving safety and economic benefits. Asphalt concrete (AC) and asphalt mastic macadam (SMA) and other traditional asphalt mixtures are commonly used as flexible bridge deck paving materials, their strength and rigidity are low at high temperatures, which cannot meet the requirements of steel bridge decks for resistance to deformation and bearing capacity. Require. Therefore, on steel bridge decks using flexible paving materials, it is easy to induce premature failures such as cracking, rutting and delamination. Compared with flexible bridge deck paving, rigid bridge deck paving has attracted more and more attention from researchers because of its great potential in improving stiffness and reducing stress. This article systematically introduces the common cast asphalt concrete (GA), double-layer SMA, epoxy asphalt concrete (EA) and cold-mix resin combined paving (ERS) steels that are commonly used in engineering from the aspects of performance and origin. Bridge deck paving materials are expected to provide theoretical guidance for the actual construction of steel deck paving.
