The present study evaluated resistance effects of fatigue cracking and subsequent reflection cracking of the basalt fiber geogrid reinforcement for asphalt mixture layers. The following findings were obtained. The stress distribution to the grid is a major factor for fatigue cracking suppression. This effect is reduced when the grid greatly inhibits the interlocking of aggregate particles between layers. There is a significant difference in the effect of reflection cracking suppression depending on the tensile strength of the grid until crack appears on the lower surface of the surface course. However, the suppression effect is not found while the crack grows and reaches to the upper surface.
