Road chip sealer truck

The Bitumen Gravel Chip Sealer Truck synchronizes the intelligent asphalt sprayer with the screw chip spiral spreader, ensuring quick contact between the asphalt binder and stone chip surfaces. This specialized equipment maximizes adhesion for gravel sealing on highway surfaces, bridge deck waterproofing, and under seal layers. Developed by TongDa for asphalt pavement construction, it enables fast synchronous spraying on highways. It can distribute asphalt and aggregate simultaneously or separately, accommodating various types of bitumen like rubber bitumen, hot bitumen, and emulsion.
