Effects of Material Design Parameters on Mechanical States of Bridge Deck Pavement

Bridge deck pavement suffers from more complicated stresses than ordinary pavement, and mechanical states of the paving layers are influenced by material design parameters. After mechanical computation, the effects of material design parameters on the mechanical state and the variation law of pavement are analyzed. Analytical results indicate that following the traditional HAM design method can not adapt to actual mechanical states, and easily result in usual distress types on the asphalt concrete paving. Economical and reasonable paving materials should be designed or developed according to mechanical paving characteristics, such as multilevel dense built-in modified HMA, fiber-reinforced asphalt concrete and modified SMA, which can harmonize paving layers as a whole, adapt to the deformations of bridge decks, improve the mechanical states of the paving layers, increase the service years, and offer some helpful references for similar bridge deck pavement design.
