Abstract:

In order to improve the mechanical performance and sustainability of road rehabilitation operations, this research sought to examine the effects of adding sugarcane bagasse ash and polyester fibers to Babylon soil on certain geotechnical parameters. Throughout the course of the experiment, soil was amended using ash alone, with and without polyester fibers, and finally with a mix of the two additives. Particularly, the results demonstrated a considerable improvement in the soil's surface bearing capacity, unconfined compressive strength, and ideal moisture content. The maximum dry density dropped even more, as one would anticipate when dealing with less dense materials than thick soil particles. The study indicates that a 20% polyester to 15% ash ratio is the optimal ash to polyester ratio. This study adds to the growing body of information suggesting that using recycled materials might enhance soil behavior. If this holds, it may reduce environmental damage by allowing newly constructed infrastructure in areas with poor soil to be replaced with recycled materials.
