Trafficked pavement substrates utilize markings to segregate traffic (e.g., divide lanes traveling in the same direction, divide sides of the road traveling in opposite directions). A dry polymer modified cement mixture may be used to provide the markings. The dry polymer modified cement mixture is prepared by mixing a dry polymer modified cement blend (ordinary Portland cement, aggregate and polymer powders) with water. The location of the lines is identified, and the dry polymer modified cement mixture is applied onto the identified areas as a thin layer. The dry polymer modified cement blend may include polymers to provide colored markings. Glass beads may be embedded into the dry polymer modified mixture before it cures to retroreflect light shined thereon. The trafficked pavement substrate may have troughs formed therein and the dry polymer modified cement markings may be formed therewithin so that the markings are flush.
