Bonded wearing course (BWC) is a high-performance ultrathin overlay that seals the existing road surface and provides a new, skid-resistant, smooth and thin (5/8” to 3/4”) hot mix asphalt (HMA) wearing course in one simultaneous operation.
BWC provides a durable, open-graded, drainable wearing surface on existing pavements showing signs of aging, surface oxidation and minor rutting to extend the life of your pavements. It is a high-performance surface suitable for all types of asphalt and concrete roads, and has given outstanding performance for several decades as a preventive maintenance on major urban highways as well as residential streets. It is ideal for places where construction delays, overpass clearance, curb reveal, wet weather visibility, tire noise and skid resistance are concerns.
