Abstract
In order to investigate the effect of reclaimed asphalt mixture content on the mechanical properties of stabilized soils, California bearing ratio (CBR) tests and unconfined compression tests were performed under various compositions. In addition, plate loading tests were carried out to observe the hardening condition of stabilized subgrade soils containing reclaimed asphalt mixture.
As a result, it was found that the unconfined compressive strength and CBR value increased with an increase in reclaimed asphalt mixture content and that the hardening rate of stabilized soil tended to change in accordance with a variation of subgrade temperature. Therefore, selecting the execution season seems to perform an important role in forecasting the effect of improvement.
