In pavement structure, short fiber reinforcing technique is hoped as an effective method for improving the stability of the subbase or subgrade layers against traffic load. In this paper, compaction behavior of short fiber reinforced is discussed by the results of laboratory compaction tests. As the results of roller compaction tests, it was confirmed that the value of dry density stably increases with an increase in the number of roller passing even if initial value of dry density at spreading was lower. At 8 passing of roller compaction, the value of realized dry density around the optimum water content become higher than the maximum dry density obtained from the Proctor test. This results shows that the current compaction control method for the subbase of pavement structure can also be applied to short fiber reinforced soil.
