What is surface dressing?Updated a year ago

Surface dressing is a road maintenance technique used to prolong the life of roadways by creating a new, protective wearing course. It involves spraying the road surface with a layer of bitumen binder (such as tar or asphalt emulsion), followed by the application of aggregate chips or small stones. 

These stones are then rolled into the binder to form an interlocking surface layer. Surface dressing is best applied during warm weather conditions to ensure the bitumen properly adheres to the existing road surface and the aggregate. It's a popular maintenance technique used by local authorities and road agencies for its efficiency and effectiveness in extending the lifespan of road infrastructure.
