Pavement Thin-layer Quick-recovering UHPC Composite Material

Pavement Thin Layer Recover UHPC : 

Patent Acceptance No.: 202310788773.X. In response to the needs of rapid repair of modern transportation systems, YKY has successfully realized the function of fast thin layer use of UHPC materials after more than one year of development and research. The common defects such as pitted surface, cracks, pits and broken slabs of concrete pavement have the defects of long traffic closure time, short service life after repair and low repair cost performance. Through the use of this patented product, maintenance effects such as thin layer (2 5mm), rapid open traffic (23h), durability (28d compressive strength≥120MPa), and high maintenance cost performance and the like can be realized, and the patent product is also applicable to concrete structure reinforcement and emergency repair projects.

Main technical index :
