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 18-inch (1.5-foot) width provides wider coverage for treating joints and areas with multiple cracks.
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 18-inch (1.5-foot) Petrotac rolls measure 18 inches wide by 108 feet long, covering approximately 18 square yards per roll. Each roll weighs approximately 67 lbs.
Petrotac is also available in 12-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.
When to Choose 1.5ft Width
The 18-inch width is commonly used for treating wider cracks, expansion joints, and areas where multiple parallel cracks need coverage. It provides more overlap than the 12-inch width, offering better protection against moisture infiltration around joints.
For treating individual narrow cracks, the 12-inch width may be more economical. For full-width coverage of larger areas, consider paving fabric interlayer products. Contact us to discuss your project requirements.
