Description

These specifications shall cover the Fiber-Reinforced, Bituminous-Membrane Surface Treatment known as “Fiberseal” when used as a Stress Absorbing Membrane (known as “SAM”), and as “Fibermat”  when used as a Stress Absorbing Membrane Interlayer (known as “SAMI”).  The furnishing and application of these items is accomplished by using a specific applicator which can be mounted on as asphalt distributor modified for applying the surface treatment of bituminous binder reinforced with glass fibers.  The applicator comprises an open-bottomed spray bar housing fan or blower for producing a down draft in the housing, and at least one (1) spray bar mounted on the housing and adapted to extend transversely in the direction of the movement of the asphalt distributor on which the unit can be mounted.  A number of nozzles spaced longitudinally along the spray bar for spraying bituminous material, means for controlling nozzles and a number of sources for dispensing cut glass fiber through the open-bottomed housing to the surface of the bituminous material previously sprayed must be included as part of the applicator.
 
Asphalt emulsion, aggregate and in-place chopped fibers are combined to form a versatile treatment, ideal for sealing as a “SAM” and arresting severely alligator cracked surfaces.  The in-place chopped glass fiber gives the surface an improved tensile strength and resilience.
 
When applied within the pavement structure, the Fiber-Reinforced, Bituminous-Membrane Surface Treatment acts as a “SAMI” for the treatment of reflective cracking prior to the construction or placement of subsequent layers.
