A pavement surface treatment, comprising a mixture of fine aggregate, asphalt emulsion, and mineral fillers, is applied to existing asphalt concrete surfaces. This application creates a thin layer designed to protect and rejuvenate the underlying pavement. For example, it can be utilized on roadways experiencing moderate wear, effectively sealing minor cracks and providing a renewed wearing surface.
This preservation technique offers several advantages, including extending the service life of pavements, improving skid resistance, and providing a cost-effective alternative to complete asphalt replacement. Its history extends back several decades, evolving alongside advancements in asphalt emulsion technology and paving practices to become a widely accepted method for pavement maintenance. By sealing the surface, it helps prevent water infiltration, a primary cause of pavement deterioration, thereby reducing the need for more extensive repairs in the future.
