Experimental investigation on dynamic characteristics of fiber-binder modified subgrade filler after freezing-thawing under cyclic loading
Transportation Geotechnics（2023）
Abstract
•Dynamic stability of fiber-binder modified subgrade filler under the long-term cyclic loading after the freeze–thaw cycle.•Effect of fiber contents, fiber lengths, additions of binder material, and freeze–thaw cycles on cumulative plastic strain.•Critical dynamic stress model of fiber-binder modified subgrade filler with multi-factor change.
