It was discovered that the contents of lobster shells can be used as materials for road construction.
As summer comes, as a Hunanese, beer and crayfish are indispensable late-night snacks. In Changsha, the capital of Hunan Province, 10,000 tons of lobsters are eaten a year. In the eyes of the general public, crayfish is a delicacy, but in the hands of this doctoral team from Changsha University of Science and Technology, it is not that simple. It has become a new material for road construction.
In June last year, after a day of scientific research and study, Professor Lu Songtao from the School of Transportation Engineering of Changsha University of Science and Technology took his team of teachers and students to the east gate of the school for a late-night snack. The must-order crayfish is of course brought to the table quickly. While looking at the small pile of crayfish shells in front of everyone, Professor Lu suddenly asked a question: Lobster shells can maintain their original shape after being exploded in oil at temperatures above 200°C, indicating that their high-temperature properties are very good. , if it is mixed into the base asphalt, will it improve the high-temperature performance of the asphalt? The professor's question aroused everyone's interest.
As soon as the question was raised, a group of teachers and students who love scientific research just did it. So for nearly a year, team members began research, experiments, and testing. The research results gradually showed that the finally developed lobster shell bio-asphalt can be used as a new road material, which can improve the material performance of traditional pavement and reduce the impact of biological waste on the environment. The team has now published this result in the journal "Journal of Cleaner Production" and applied for a national invention patent. Many inventions come from life, from everyone's observation of things in life, plus their own research on professional knowledge. Professors can lead students to discover new things, which reflects that research should enter life and study things around them. Life is full of science. As long as we observe carefully and study patiently, we can always discover different scientific results. It is this innovative spirit that is good at discovery and research that promotes the continuous progress of science. Promoted the scientific and cultural process of mankind.
