Latest Patents

One of Kai Yuan's key patents is titled "Method of paving a roadway using hydrogel modified subgrade." This invention presents an adjustment method of moisture content and dense state for a hydrogel improved subgrade based on weather-resistance during an in-service period. The method includes several steps: first, carrying out surface cleaning and compaction of the ground; second, preparing hydrogel improved subgrade raw material; third, paving the prepared material on the surface to form the first-layer improved subgrade; and finally, paving plain soil subgrade onto the first-layer. This innovative method combines the water absorption and release function of the modified resin with the gel state characteristics, allowing for layered paving that can absorb water and expand slightly when the moisture content in the subgrade reaches a certain threshold. Additionally, it forms a strength and compactness protective layer at the connection sections of the ground and the subgrade, as well as between the subgrade and the pavement, effectively preventing the pot-cover effect from occurring. Kai Yuan holds 1 patent for this groundbreaking invention.
