Experimental study of polyurethane-cement composite reinforcing talik beneath subgrade in permafrost regions: Exothermic characteristics, durability and micro-mechanism

Permafrost degradation induces the expansion of talik, which has high water content, low bearing capacity, and high compressibility, constantly threatening the safe and long-term service performance of local engineering structures and practices. Therefore, adopting effective measures to address tali...
