Specifications include, but are not limited to: Asphalt Sealant shall conform to Federal Specifications SS-S 164 as manufactured by Allied Materials, W.R. Meadows, Inc., and Nesco, or approved equal. Fiber reinforcing materials shall be short-length polyester fibers having the following properties: Length 7mm Diameter 0.0008 inch plus or minus 0.0001 inch Specific Gravity 1.32 to 1.40 Melt Temperature 480 degrees F. minimum Ignition Temperature 1000 degree F. minimum Tensile Strength 75,000 PSI plus or minus 5,000 PSI Break Elongation 33% plus or minus 9% They are fully drawn Asphalt-fiber compound shall be mixed at a rate of 6-8% fiber weight to weight of asphalt cement. This compound having the same chemical base provides compatibility and exhibits excellent bond strengths. The fiber functions to redistribute high stress and strain concentrations that are imposed on the sealant by thermal sources, traffic, loading, etc.
