Cold patch is a high-tech road repair material that can generally be used around the clock, suitable for repairing various types of road surfaces in any weather and environment, such as asphalt concrete roads, cement concrete roads, parking lots, and airport runways.

After years of continuous improvement and refinement, the performance of cold patching materials has become more mature. Both in terms of quality and usage, they outperform hot-mixed asphalt, emulsified asphalt blends. Thanks to their simple operation, long storage, high-quality repairs, wide applications, and environmental benefits, they have been adopted globally and extensively used in many municipal roads, general highways, and expressways within the country. Cold patch materials exhibit excellent adhesion with different substrates such as asphalt concrete, cement concrete, and metallic surfaces, making them widely applicable for repairs and maintenance on various road surfaces including highways, general roads, municipal roads, airport roads, and bridges.
