Latest Patents

Dalu Xiong holds a patent for a method of paving a roadway using hydrogel modified subgrade. This patent outlines 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 approach 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 moisture levels increase. Additionally, it forms a protective layer at the connection sections to prevent the pot-cover effect from occurring.
