SECTION 406 - ASPHALT PAVEMENT WITH FIBERS
406-1 DESCRIPTION. This work shall consist of formulation and placement of a fiber reinforced
asphalt mixture. The placement of this mixture shall be in accordance with these specifications and in reasonably close conformity with the required lines, grades, thicknesses, and typical sections shown on the plans or established by the Engineer.
406-2 MATERIALS. The requirements of §401-2 and §404-2, Materials, shall apply with the
added information noted below.
A.Fibers. Aramid fiber shall meet the requirements of Table 1 – Aramid Fiber Properties. The acceptance shall be based on the certification from the supplier of fibers.

1.Delivery. The fibers shall be delivered in a sealed undamaged container with legible labels indicating material name and lot number.
2.Storage. The fibers shall be stored in accordance with manufacturer’s recommendations. The fibers shall be protected from UV radiation, contamination, or becoming wet.
406-3 CONSTRUCTION DETAILS. Provisions of §401-3 and §404-3, Construction Details, shall
apply with the added information noted below: The fibers shall be added to the asphalt mixture at a rate recommended by the fiber supplier. The minimum rate of aramid fiber added to the mix shall be 2.0 ounces per ton. The fiber product shall be added to the asphalt mixture at a rate recommended by the fiber supplier that will provide at least 2.0 ounces of evenly distributed aramid fibers per ton of asphalt mixture. The fibers shall be added to the asphalt mixture through specialized equipment that can accurately proportion and meter, by weight of total mix, during production of asphalt mixture. The equipment shall be calibrated to the satisfaction of the Regional Materials Engineer showing the fiber is being accurately metered and uniformly distributed into the mix by visual inspection. When a batch plant is used, pre - weighed bags of fiber may be add ed per batch to provide the designed quantity of fibers in the asphalt mixture. Additional requirements for plants are as follows:
1.Batch Plant. When a batch plant is used, the fibers shall be added to the pugmill and follow the manufacturer’s recommendations for both the dry and wet mixing times. The fibers shall be uniformly distributed before the injection of asphalt cement (Performance-Graded binder) into the mixture.
2.Drum Mixer Plant. When a drum plant is used, the fibers shall be introduced such that there is no entanglement in the exhaust system. If there is evidence of clumps of fibers at the discharge chute or on the project, the production of asphalt mixture shall be stopped and follow the fiber manufacturer’s procedures to reduce clumping.
