摘要

This study investigates the use of Reclaimed Asphalt Pavement (RAP)-infused granular piles to enhance the load-bearing capacity and settlement performance of soft clay soils, increasingly utilized due to urbanization. Ordinary and Geotextile-Encased Floating Granular Piles (OGP and EGP) were evaluated through load-settlement tests across various RAP-to-stone aggregate ratios, with large-scale experiments and PLAXIS 3D simulations validating the results. The optimal mix of 50% stone and 50% RAP improved soil properties by balancing stiffness and flexibility, while geotextile encasement further enhanced performance by reducing lateral deformation and optimizing load transfer. Specifically, the geotextile-encased 50S-50R pile increased the ultimate bearing capacity by 29% compared to the 100% stone configuration. Although higher RAP content mixes were less effective due to lower stiffness, their performance improved significantly with geotextile encasement. The findings demonstrate that RAP-infused granular piles, especially when geotextile-encased, offer a viable and sustainable solution for soft soil improvement, promoting environmental and economic benefits in geotechnical engineering.
