Applications
• Highways and expressways
• National and provincial roads
• Urban streets and municipal roads
• County and rural roads
• Airport pavements

Purpose
This machine is used prior to asphalt crack sealing to cut a clean, consistent groove along existing pavement cracks. The grooving process allows sealant materials to penetrate deeper into the pavement structure, improving adhesion, enhancing overall pavement performance, and extending road service life.
