A STUDY OF THE STRAIN BEHAVIOR OF ASPHALT PAVEMENT ON STEEL DECK PLATE BY VISCOELASTIC ANALYSIS

Abstract

 Last year, positive bending test used asphalt mixture and steel composition specimens was performed by dynamic loading. In the study, it was found that there were many cases tensile strain occurred in asphalt pavement though asphalt mixture was deformed to positive bend. So, in this study, viscoelastic analysis was performed. As a result, it was able to be found tensile strain similar to experiments was occurred. And it was able to be reproduced strain behavior of asphalt mixture that was not able to be reproduce d by liner elastic analysis. In this study, it was able to be confirmed that viscoelastic theory was necessary to understand strain behavior of asphalt pavement on steel deck plate.
