Pothole patching main charges involve materials, labor, and equipment. Usually, the highest cost is devoted to crew and equipment, and the cost of materials is just a small portion of the total patching costs. CMPMs contribute 20% of the overall repair cost, while this value for hot mix asphalt is 2–5%.
