Overlay products and materials function to increase performance, reduce costs and deliver measurable results by working with our customers to provide advanced solutions.
The Difference a Nonwoven Overlay Makes:
L.E. Geosolutions’ glass-fiber (RG) geogrids are used to help retard reflective cracking in the asphaltic layers within flexible and composite pavements. They comprise extremely stiff fiber-glass strands knitted together to form a grid structure and then coated with an elastomeric polymer. For ease of installation, if required, the products can be supplied with adhesive on the underside to help bond them to an existing asphalt surface.
For 50 years, the paving industry has relied on PETROMAT® as the most trusted asphalt paving fabric in the market. This year, Propex GeoSolutions is thrilled to launch only PETROMAT® Enviro. Combining innovation and sustainable design, this patent-pending technology is engineered to easily mill into small pieces so it can be recycled into reclaimed asphalt pavement (RAP)and used in new hot mix asphalt (HMA) or warm mix asphalt (WMA). Additionally, Enviro provides unmatched moisture protection for roads while absorbing stress to slow fatigue and reflective cracking in asphalt pavement. But recyclable is half the story. Enviro is an engineered interlayer solution that outperforms the competition from start to finish.
PETROMAT® engineered paving fabrics are used as a moisture barrier and stress absorbing interlayer beneath flexible pavements such as asphalt overlays or a chip seal. PETROMAT is unchallenged in the industry for asphalt pavement interlayer application. It is AASHTO/NTPEP compliant and is available in a variety of styles to fit your specific project needs and specifications.

NW-75 Pavement Underseal Membrane
Designed for concrete or asphalt repair on localized areas with failure amounting to less than 10% of the pavement surface area. The membrane is used prior to an asphalt overlay, and when placed on joints and pavement cracks, it will waterproof and reduce the extent and severity of reflective cracking. If installed on bridge decks, it acts as a waterproofing membrane, protecting and reinforcing steel in the deck from corrosion. The non-woven open fibers of the geotextile fabric backing on NW-75 provide a strong mechanical bond to the asphalt overlay.
665 Pavement Underseal & Waterproofing Membrane
Avery tough self-adhering Peel-n-Stick waterproofing membrane for bridge decks, parking garages, and joint & crack repairs. The woven polypropylene mesh fabric backing has strong puncture resistance. The membrane is cold-applied and requires no special adhesives or heating equipment.
The GlasGrid® Asphalt Reinforcement System is composed of fiberglass strands coated with an elastomeric polymer and formed into a grid structure. Each strand has a remarkably high tensile strength and high modulus of elasticity; this is particularly important as asphalt concrete typically cracks at low strains.
When the GlasGrid System is sandwiched between the leveling course and the surface course in an asphalt overlay, it becomes the hidden strength in the road, turning vertical crack stresses horizontally to effectively dissipate them.
For road construction projects that require a moisture barrier, Tensar offers the GlasGrid® CG (Compogrid) System. Incorporating a lightweight polypropylene fabric on the back of the main grid component, GlasGrid CG provides additional pavement protection on both new construction and pavement rehabilitation projects.
The GlasPave® Mat’s capabilities are well suited to all pavement surfaces. Its geosynthetic, non-woven polyester matrix enables an asphalt binder to fully penetrate and fill voids within the matrix, limiting the infiltration of surface moisture into the granular layers of a pavement structure, ultimately preserving the strength of these layers. The matrix design also promotes a quick, strong bond with a variety of asphaltic tack coats. And like the GlasGrid® Asphalt Reinforcement System, the GlasPave Mat performs well even in the harshest environments similar to the GlasGrid® Asphalt Reinforcement System.
PavePrep is a heavy-duty, high-strength pavement repair geocomposite membrane used to reinforce and waterproof pavement cracks and joints, reduce reflective cracking of asphalt concrete overlays, and as a heavy-duty bridge deck waterproofing membrane. PavePrep comprises a flexible, high-density asphalt mastic bitumen between a top layer of heat-resistant, high-strength woven polyester reinforcing fabric and a bottom layer of non-woven heat-resistant polyester fabric. PavePrep is supplied in several widths in 50 ft. lengths and is wound on rolls. To use, PavePrep is unrolled onto prepared pavement surfaces into an application of bonding adhesive that saturates and adheres PavePrep to the surface, then pressure rolled to secure it into place. The asphalt concrete overlay is then placed. PavePrep can be used to reinforce many discontinuities in both asphalt and concrete pavements, including transverse and longitudinal cracks and joints, utility cuts, construction joints, and previously repaired areas. The PavePrep polyester fabrics are resistant to asphalt concrete pavement overlay temperatures up to 350°F (177°C) and hot-applied sealing mastic application temperatures up to 375°F (191°C).
PavePrep SA is a heavy duty, high strength geocomposite self-adhesive membrane used to reinforce and waterproof pavement cracks and joints, to reduce reflective cracking of asphalt concrete overlays, and as heavy duty bridge deck waterproofing membrane. PavePrep SA is composed of a flexible, high density asphalt mastic bitumen between a top layer of heat resistant, high strength woven polyester reinforcing fabric and a bottom layer of non- woven heat resistant polyester fabric with a polymer modified asphalt self- adhesive layer and removable release liner. PavePrep SA is available in several widths in 50 ft. lengths and is wound on rolls. To use, PavePrep SA is removed from the box, unrolled onto prepared pavement surfaces while removing the release liner to expose the self-adhesive layer, and then pressure rolled to secure in place. For some uses, and when pavement surface temperature is below 70°F (21°C), primer is required prior to installation. The asphalt concrete overlay is then placed on top of the installed PavePrep SA membrane. PavePrep SA can be used to reinforce and waterproof many discontinuities in both asphalt and concrete pavements, including transverse and longitudinal cracks and joints, utility cuts, construction joints, and previously repaired areas. The PavePrep SA polyester fabrics are resistant to asphalt concrete pavement overlay temperatures up to 350°F (177°C) and hot-applied sealing mastic application temperatures up to 375°F (191°C).
