What Is Petrotac?
Petromat Petrotac is a self-adhesive paving strip membrane geotextile designed to treat local pavement distress, joints, and cracks in asphalt surfaces. It is also used as a bridge deck moisture barrier. The 12-inch (1-foot) width is ideal for treating individual cracks and joints.
It is manufactured by TenCate Geosynthetics Americas (a Solmax company) and tested in a GAI-LAP accredited laboratory. This product meets Build America, Buy America Act requirements.
Mechanical Properties
Petrotac has strip tensile strength of 75 lbs/in and puncture resistance of 200 lbs. The permeance is 0.05 perms maximum, making it an effective moisture barrier. It passes pliability testing at -25°F on a 1/4" mandrel with no cracks in fabric or rubberized asphalt.
Asphalt retention exceeds 0.20 gal/yd² and the melting point is 325°F. UV resistance is 70% after 500 hours exposure. The product requires minimum asphalt overlay temperature of 280°F during installation.
How It Works
The self-adhesive backing bonds to the existing pavement surface, creating a moisture barrier and stress-absorbing layer. When hot asphalt is applied over the Petrotac, the rubberized asphalt in the membrane bonds with the overlay, helping prevent moisture infiltration and reflective cracking.
The membrane absorbs stress from underlying crack movement, reducing the transfer of that movement to the new overlay. This can help extend pavement life and reduce maintenance costs.
Roll Sizes
The 12-inch (1-foot) Petrotac rolls measure 12 inches wide by 108 feet long, covering approximately 12 square yards per roll. Each roll weighs approximately 44 lbs.
Petrotac is also available in 18-inch, 24-inch, 36-inch, and 48-inch widths for different applications. Contact us for current availability and to discuss which width is best for your project.
Common Applications
The 1-foot width is commonly used for treating individual transverse and longitudinal cracks, joint sealing prior to overlay, and spot treatment of localized pavement distress. It is efficient for crack repair work where full-width interlayer coverage is not needed.
For full-width coverage of larger areas, consider using paving fabric interlayer products instead. Contact us to discuss your project requirements and we can recommend the most appropriate solution.
