Saw & Seal.
Sawing and sealing is an effective way to protect airport pavement joints from water intrusion and subbase failures. Installing dedicated elastomeric control joints provides the very necessary extra flexibility our pavements need.
Process
After laying new pavement, such as hot mix asphalt (HMA), anywhere within the Air Operations Area (AOA), new control joints (approximately ½ inch wide by 1 inch deep) are sawed into the surface at predetermined transition points. These new joints are then filled with a fiberized asphalt cement or ASTM D6690 sealant.
Benefits
- A proactive way to protect pavement
- Prevents other cracks from forming on the surface
- Prevents water from penetrating to the subbase
Consider Saw & Seal when
you’re constructing a new runway, rehabilitating an old one, or doing any pavement repairs within the AOA.
