MCDA C-720 クラックシーリングマシン 
The MCDA C-720 Crack Sealing Machine is a high-performance road maintenance system designed for the efficient sealing of cracks in asphalt and concrete pavement surfaces. It delivers continuous, controlled injection of hot-melt sealing material into pavement cracks, creating a durable, waterproof bond that prevents water intrusion and inhibits further crack growth. This extends pavement service life and reduces the need for frequent repairs.
