    The document provides design specifications for a rigid pavement as per IRC: 58-2015. It includes material properties, load parameters, and design procedures. The slab thickness was designed to be 220mm. Stress analyses were conducted at the edge and corner regions under wheel and temperature loads. All calculated stresses were found to be less than the flexural strength of the concrete, indicating the design is safe and meets code requirements.
