Sand reinforced with randomly oriented short polypropylene fibers (fiber reinforced sand, fibrosand, FRS) was tested to determine creep characteristics. This study is a part of research aimed at encouraging FRS application in subsoils, embankments and retaining wall constructions. Natural non-treated sand was used as a base material. Commercially available polypropylene fibers of 12 mm in length were used as reinforcement. Fiber content accounted for 0.93 %. Twin samples of FRS were put to creep tests using the two curve method. The test results were analyzed and checked with the use of ageing, hardening and hereditary creep theories. The results of a prolonged creep test on the samples under constant load were used to fit the creep parameters by the FORE method. The methodology and creep test results on FRS are given and discussed in the paper.
