How much hot mix asphalt should I use with a paving geotextile?

Standard practice is 2.5 inches. Your project requirements may vary.

What is the preferred tack coat?

Uncut asphalt cement is the preferred sealant to impregnate and seal the geotextile, as well as bond it to the pavement. Uncut asphalt cement is preferred because it develops adhesive strength quicker.

What is the application rate for the tack coat?

The application rate of the tack coat depends on the porosity of the existing pavement. Apply the tack coat at a distribution range of 0.20 gal/sy to .30 gal/sy.

Can the use of a paving fabric reduce design thickness?

Studies have shown that a reduction of 0.5 inches is reasonable.

Will paving fabrics eliminate cracking?

Paving fabrics will reduce reflective cracking. However, they will not eliminate it. The good news is that if a crack does reflect up, the paving geotextile system still functions a waterproof membrane and prevents water from passing through.

Can I use a paving geotextile with chip seal?

Paving fabrics do work with chip seals.

Can I use a paving geotextile over milled surfaces?

Yes, you can use a paving geotextile over milled surfaces. Please read the section on milled surfaces in our on-line apshalt overlay fabric installation guideline. A link is provided below under "Helpful References."

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

US Fabrics offers two grades of paving fabrics: US 90P and US 100P which satisfies the AASHTO guidelines for paving fabrics.
