Paving Geotextiles

According to AASHTO, the number one cause of roadway deterioration is water saturating the subgrade below the pavement. The FHWA states that up to two-thirds of the water that strikes an asphalt surface passes through to the subgrade. Water softens the subgrade, reducing the structural capacity of the pavement by as much as 60%. In fact, a pavement with a base that is saturated a little as 10% of the time will only have half the life-span of a pavement with a dry base.

Paving fabrics are nonwoven, needle-punched polypropylene fabrics that have a forty year history of improving pavement performance and extending pavement life. Properly installed, paving fabrics are an important part of an overlay system that can:

• Eliminate water intrusion through the asphalt
• Slow reflective cracking
• Increase the flexibility of the pavement system

General Installation Guidelines

Uncut asphalt cement is applied as tack coat to impregnate, seal and bond the paving fabric to the pavement. The application rate of the tack coat depends on the porosity of the existing pavement. The paving fabric is placed with the untreated (fuzzy) side against the existing pavement while the tack coat is still tacky. After fabric placement, proceed with standard paving operation.
