The School of Transportation at Southeast University primarily undertakes research and development of road engineering materials and technical breakthrough for transportation infrastructure in the construction of South China Sea islands and reefs. Targeting the high-temperature, high-humidity, and high-salinity environment of these islands, the school's researchers systematically studied the road performance of cement-stabilized coral reef rock and sand filling materials. Through a series of experiments, they investigated the strength, stiffness, water stability, and shrinkage properties of these materials, proposing solutions for using such materials as base courses for island and reef highways to achieve resource-efficient utilization. Simultaneously, the school participated in the design and construction technical breakthrough for transportation infrastructure including roads, airports, ports, and shore protection facilities on the islands, with several key technologies successfully applied in major projects such as the South China Sea island and reef construction, effectively addressing the durability issues of traditional road engineering materials under the harsh island and reef environment.
