Abstract

Abstract

To discuss the applicability of domestic hard bitumen in bridge deck gussasphalt paving, the types of overseas common hard bitumen were analyzed, domestic hard bitumen, PmB45 made in laboratory and PmB25 made in Germany were selected, by means of indentation test, wheel track test, bending beam test and fatigue test, the performances of the gussasphalts made with the hard bitumens were evaluated. The result shows that the performances of the gussasphalt made with domestic hard bitumen meet the criterion of gussasphalt binder, the bending and fatigue performances of the gussasphalt made with modified hard bitumen excel that of the gussasphalt made with direct hard bitumen, but the rut resistances of the three kinds of gussasphalts are limited, and it is proposed that the made gussasphalts may be used in northern China.
