Rutting is one of the most typical distresses for asphalt pavement. Under repeated heavy vehicle loads and high-temperature weather, asphalt mixtures are prone to permanent deformation, forming grooves on the road surface. Rutting will reduce driving comfort, bring safety risks and increase road maintenance costs. High-performance asphalt additives have become an efficient solution for this problem.

Concrete admixtures are chemical or mineral ingredients added to concrete during mixing, to modify the workability, setting time, strength, durability and other performance of concrete. They are widely used in highway, bridge, building, dam and precast concrete projects.

On November 24, 2025, an expert review was conducted at the Ministry of Industry and Information Technology in Beijing. The technological innovation achievement "Research and Development of High-Performance Asphalt Additive High-Viscosity Technology" from Changzhou Lierdetong New Material Technology Co., Ltd. was recognized.
