This comprehensive review examines the critical challenges and innovative solutions for constructing rigid pavements on soft peat soil foundations. Peatlands, characterized by high compressibility, low shear strength, and acidic conditions, necessitate specialized engineering approaches to ensure structural integrity. The analysis synthesizes findings from recent studies on elastic foundation models (e.g., Winkler’s approach) and finite element simulations, revealing that deformation is governed by pavement thickness and load intensity. Key advancements include sustainable material innovations—such as geopolymer concrete, palm oil fuel ash, and foam concrete—which enhance durability in acidic environments. Stabilization techniques using industrial byproducts and biochar are highlighted for minimizing settlement, while lightweight materials and floating foundations offer subsidence mitigation. The review underscores the environmental and economic benefits of these strategies, advocating for integrated approaches to achieve resilient and sustainable infrastructure in peatland regions.
