Theoretical and Experimental Analysis on Bending Creep Characterizations of Asphalt Concrete Using Modified Method
The analytical solution of asphalt concrete bending creep test was established based on bars mechanics theory. The beam end slope was solved using numerical method, and the calculating method of strain rate in bending creep which is based on small deformation theory was modified. The equations of strain rate and correction factors were obtained for bending creep test. The changing in the effective span of the beam resulted in creep strain changing. This improved theory can be used to explain strain rate variation with the temperature effect. It reduced the limitations of small deformation theory, and has more accuracy in calculating strain rates for large deformation bending creep at medium temperatures. It provides a theoretical basis for accuratly analyzing the bending creep behaviors of asphalt concrete.
