Abstract
In view of the increasing application of steel residue in asphalt pavement construction in China, in order to analyze the less temperature flawing resistance of steel residue asphalt composition, the less temperature semi-circular bending test (SCB) was used to analyze the less temperature flawing resistance of steel residue asphalt composition (SSAC-13) with various residue content based on the stress peak value and stress attenuation, rupture toughness, rupture energy and critical rupture energy density. The results show that the content of steel residue has a noticeable influence on the less temperature flawing resistance of steel residue asphalt composition. Considering the less temperature flawing resistance, the recommended steel residue content is 40%.
