Abstract: For the rehabilitation of degraded road pavements, thin concrete overlays have become a popular choice. These overlays, which are typically 1 to 4 inches thick, offer a number of advantages, including increased structural capacity, higher longevity, and less maintenance requirements. Thin concrete overlays increase resistance to cracking and rutting and lengthen the lifespan of deteriorating pavements by restoring their capacity to carry weight. Additionally, they provide design flexibility by allowing for the alteration of color, thickness, and texture. They also save money over the long run by requiring fewer repairs down the road and little surface preparation. As a beneficial and long-lasting solution for repairing road surface, thin concrete overlays are used.
To summaries, thin concrete overlays provide an innovative and sustainable solution to repairing and prolonging the service life of road pavements. They are a vital asset in contemporary pavement rehabilitation practices because of their capacity to improve structural capacity, durability, and aesthetics while offering affordable alternatives. The creation of durable and long-lasting road infrastructure can benefit greatly from additional research and application of thin concrete overlays.
