The compressive strength test was performed for 7 days and 28 days. The 7th day and 28th day compressive strength was maximum for an optimum 1% basalt fibre. The compressive strength of high density concrete increased with an increase in fibre dosage up to 1%, and further increase in dosage decreases the compressive strength.

When the curing age was 60 d, the compressive strength initially increased and then decreased when the fiber content was increased. When the basalt fiber content was increased from 0 to 0.3%, the compressive strength of the backfill reached a maximum value of 6.40 MPa, which was 45.5% higher than that of the original GCB.

Freeze–thaw (F–T) cycling poses a significant challenge in seasonally frozen zones, notably affecting the mechanical properties of soil, which is a critical consideration in subgrade engineering.

σ 1 and σ 3 denote the maximum and minimum (confining pressure) principal stresses, respectively; σ ci represents the uniaxial compressive strength of the intact rock; and m is the rock material constant.
