Surface Treatments:
FiberMat® SAM

FiberMat® is a high performance, skid resistant surface treatment. It is constructed with a one-pass application of a sandwiched matrix of asphalt polymer modified emulsion, chopped fiberglass fibers and a second layer of emulsion. The strong, adhesive membrane is covered with stone seal aggregates. The tensile strength of the fibers gives outstanding reinforcement to the surface, bridging cracks, voids and other distresses in the existing pavement. The emulsion seals the surface and binds the aggregate top layer. The stone provides a durable, skid resistant surface. The interconnecting bonding of cured asphalt, fibers and aggregates results in a very tough, very durable surface. The process may be used as preventive and corrective maintenance on distressed asphalt, concrete and composite pavement surfaces. All States Materials Group is proud to bring this effective, innovative technology to you, our customers.

FiberMat® Benefits

  • Increases strength with fiberglass fibers, resisting stresses placed on the surface treatment
  • Waterproofs and seals small cracks and imperfections
  • Enriches aging, oxidized asphalt
  • Improves skid resistance
  • Protects underlying pavement from traffic wear
  • Protects the environment and worker safety with non-polluting, water-based emulsion
  • Ultrathin, preserving curb reveal and clearances under bridges and overpasses
  • Quick application and traffic return
  • Effective preventive and corrective maintenance for a long-lasting wearing course that protects and extends the life of your pavement

The FiberMat® Application Process

As with all of our paving projects at All States Materials Group, we begin with a design in our laboratory using the project materials. We formulate the polymer asphalt emulsion to break quickly and be compatible with the fibers and project aggregate, and we design the application rates for the specific project site to give the highest strength surface that satisfies your requirements. After any severe cracks and base and drainage problems are repaired, All States Materials Group’s trained crew uses an innovative trailer-mounted machine that is equipped with two slot-jet spray bars, a fiber chopping mechanism and compressed air. The first spray bar applies the asphalt emulsion. The machine then uses compressed air to expel the fibers from the chopping mechanism. The fiberglass comes on spools and is cut by the mechanism in the application machine to lengths from 1.2 to 3.5 inches. The operator controls the fiber length and coverage by the blade and rotation speeds. The fibers are immediately covered with emulsion by the second spray bar. The emulsion is typically applied at a shot rate of 0.2 to 0.25 gallons per yd2 for each of the two applications, and the fiberglass at 2 to 4 ounces per yd2. We immediately apply the 3/8” or 1/4” stone seal aggregate with a chip spreader, at typical stone seal rates (just enough aggregate to cover the emulsion). Once the emulsion has set, the surface is rolled, typically within 15 minutes, regardless of temperature or humidity. The surface is then ready for a very quick traffic return. The system can be applied as a single or double seal resulting in finished thicknesses of between 1/4 to 3/4 inch.

Where and When to Use FiberMat®

FiberMat® is the ideal, high-performance treatment for correcting and protecting structurally sound pavements with aging or distressed surfaces. Over blacktop or concrete, FiberMat® waterproofs and seals cracked and crazed surfaces, restoring skid resistance and enhancing appearance. It is suitable for all types of pavements with distressed surfaces, from rural roads to high traffic highways. The surface may have low skid resistance, small cracks, raveling and aging asphalt or concrete. For preventive maintenance, the pavement to be sealed should be essentially sound and properly drained. It should have a good profile and alignment with only minor asphalt aging and cracking. There should be no sign of sub-base movements or surface bleeding. When warranted, potholes and cracks should be filled. The surface should be swept of any stones, sand, mud or other loose debris. Because it is an emulsion application, FiberMat® construction should be done on warm, dry days.

All States Materials Group wants to make sure your surfacing job is a success. We can help with determining the right treatment at the right time for your pavement. For your overall road program, we can help you evaluate single versus multiple surface treatments as well as other alternatives for cost-effective pavement preservation.
