An experimental study on strength improvement of expansive subgrades by polypropylene fibers and geogrid reinforcement

open access: yesScientific Reports, 2022
The rapid development of infrastructure often encounters the loose subgrades and is becoming difficult to carry to construction activities. Numerous counteracting methods are developed to control the swelling-shrinkage behavior of the expansive subgrades.
