No specifications were initially available for the pavement of the overflow bank. Therefore, the design was finalized through repeated investigations, proposals, and discussions with supervisors. Leveling and surface course installation work were achieved through overlaying. Given the construction’s goal of achieving a specific height, each layer’s thickness was carefully measured to ensure accurate pavement thickness. As a safety precaution, workers involved in the pavement work wore safety belts and life jackets as an additional measure. Carrier trucks transported composite materials to prevent rollover and turning accidents.
