Effect of Stabilized Subgrade on Rutting Resistance of Asphalt Concrete Pavement
Pavement distress has become a common issue nowadays due to the increased traffic growth, overloading, inferior pavement materials, etc. Rutting is one such major pavement distress that reduces the long-life performance of flexible pavements. This study aims to a systematic study and analysis of the rutting behaviour of conventional asphalt concrete (AC) pavements on stabilized subgrades by using the finite element method. In this study, subgrade stabilization is done using different percentages of nano-silica and cement. Initially, the focus is paid to check the effect of nano-silica in subgrade stabilization, and then to check the effect of these stabilized subgrade materials on the rutting resistance of flexible pavement under the action of both static and repeated traffic loading conditions. Different pavement models are created in finite element-based software having stabilized subgrade. From the test results, it is found that the strain and rutting generated in AC pavement on stabilized subgrade are much lower than the AC pavements with the natural subgrade. From the static loading and dynamic loading test results, it is found that the vertical strain in the subgrade and rutting in asphalt layer can be reduced up to 60–69% and 18–22%, respectively, after adding 2% nano-silica with 6% cement.
