In order to investigate influence to cohesion c and liquefaction resistance of base course material by asphalt emulsion addition amount, undrained triaxial compression tests and cyclic triaxial tests were carried out. From the results, cohesion c was increased as increasing asphalt emulsion addition amount. Asphalt emulsion addition amount was 17%, cohesion c was reached to 12.0 kN/m2, this value is the maximum in this study. On the other hand, liquefaction strength ratio defined shear stress during liquefaction after 20 loads was RL20 =0.27 at 10% emulsion addition amount, cyclic shear strength ratio didn't change even if the asphalt emulsion addition amount was some increased further. However, the liquefaction resistance when loaded with the small shear stress increases with increasing asphalt emulsion addition amount.
