A dry polymer modified cement to receive topical aggregate to form a high friction surface on trafficked pavement substrates (asphalt, concrete). The dry polymer modified cement is a thin overlay that handles the load of traffic in a relatively short time and has a relatively long life cycle. Prior to curing, the dry polymer modified cement also acts as an adhesive layer to receive and hold aggregate that is applied thereto. The dry polymer modified cement is prepared by mixing a cement mix with water where the cement mix includes cement (ordinary Portland cement), dry polymers and aggregate. The aggregate may have gradations that meet the ASTM C144 specification or may have finer gradations to allow for easier penetration of the topical aggregate by the dry polymer modified cement. The high friction surface may be patterned to provide improved performance.
