5. Conclusions
- (1)
- Under different CAR conditions, the dry density first increased and then decreased with an increase in the water content. When CAR was 4:6, the optimum water content and maximum dry density reached the maximum values simultaneously, which were 10.1% and 2.03 g/cm3, respectively;
- (2)
- With the increase in CAR, CBR increased first and then decreased, and when CAR was 4:6, CBR reached a maximum value of 42.5%;
- (3)
- With the increase in shear displacement, the variation tendency of shear stress showed a rapid increase at first, then a slow decrease, and finally tended to be stable;
- (4)
- With the increase in CAR, the maximum shear strength first increased and then decreased, and reached its maximum value when CAR was 4:6;
- (5)
- The shear strength of the mixture increased with an increase in normal stress;
- (6)
- As the amount of coarse aggregate increased, the shear strength of the mixture increased and then decreased. When P4.75 was 40%, the shear strength of the LFCWM was the maximum.
