The "One Road Guardian" team at Harbin Institute of Technology is pushing a new research achievement - an intelligent design platform for high-performance maintenance materials based on large models - into practical applications. The platform analyzes road condition data through machine learning and can automatically generate maintenance material design schemes that are suitable for different environments. This not only significantly reduces costs, but also shortens the material development cycle by half. This summer, the members of the 'Guardian All the Way' team did not stop in their tracks. In the asphalt and asphalt mixture laboratory, they are fully committed to researching the performance optimization of rural road maintenance materials. Under the guidance of the team mentor, they systematically conducted research and development experiments on road maintenance materials. Faced with the dilemma of complex asphalt material design formulas, they jointly discussed the progress of experiments, explored the evolution laws of material properties, and worked overtime to complete numerous performance verification tests, all in order to better serve the rural road maintenance industry. You are involved in transportation, can you help us repair the road? ”Under the scorching sun in Luntai, Xinjiang, Abdullah, a fruit farmer from Yeyungou Village, held the hand of Guo Chi, a 2024 master's student from the School of Transportation Science and Engineering, with his rough palm and said. The cracks in the road behind him crisscrossed the apricot orchard. The freshly picked apricots were placed in baskets, and as the wheels rolled over the cracks, the apricots "danced" in the baskets, bouncing out quite a bit along the way. This scene became the opportunity for the birth of the "One Road Guardian" team at Harbin Institute of Technology. Through on-site research in the fruit farming industry, we realized that in today's era of interconnected road networks, there are still rural roads that urgently need to be protected. ”Team leader and doctoral student of the School of Transportation Science and Engineering at Harbin Institute of Technology, class of 2022, said Wang Yajie. In response to the problems of wide crack range and difficult maintenance of rural roads, team members worked day and night to develop maintenance materials suitable for rural roads, and finally successfully completed the construction. Previously, it was difficult to walk on the rural roads, but now less than 5% of apricot trees are lost when transported from the fields to our homes! "After the road was repaired, Abdullah and other villagers highly recognized the team's work. This story is happening in over 30 villages. In order to solve the problems of wide road cracks and difficult winter snow driving in Huwan Village, Xinyang, Henan, team members and guidance teachers have explored several ways. Under the guidance of team leader Professor Tan Yiqiu, they have developed a self melting snow repair material, which not only repairs road cracks but also equips the road with the ability to melt ice and snow; The most exciting thing for the team is that they have gradually explored a new maintenance model of "technology+cooperation" - linking with local village committees, training villagers to participate in road maintenance, which not only solves the problem of insufficient professional strength, but also drives villagers to find employment at their doorstep. In the future, we hope to explore a more mature model, attract more students to join, and contribute to the construction of a strong transportation country. ”Professor Dan Liyan, the team mentor, said.
