摘      要：This study investigated the use of recycled tire-derived aggregate(TDA)mixed with kaolin as a method of increasing the ultimate bearing capacity(UBC)of a strip *** 1g physical modeling tests were prepared in a rigid box of 0.6 m×0.9 m in plan and 0.6 m in *** sample preparation,0%,20%,40%,or 60%(by weight)of powdery,shredded,small-sized granular(G 1–4 mm)or large-sized granular(G 5–8 mm)TDA was mixed with the kaolin.A strip footing was then placed on the stabilized kaolin and was caused to fail under stress-controlled conditions to determine the UBC.A rigorous 3D finite element analysis was developed in Optum G-3 to determine the UBC values based on the experimental test *** experimental results showed that,except for the 20%powdery TDA,the TDA showed an increase in the UBC of the strip *** kaolin mixed with 20%G(5–8 mm),the UBC showed a threefold increase over that for the unreinforced *** test with 20%G(1–4 mm)recorded the highest subgrade *** was observed that the UBC calculated using finite element modeling overestimated the experimental UBC by an average of 9%.
