The invention provides melt-spun polyolefin/polyarylate alloy fibers having an elevated softening point. These fibers are useful in staple lengths for the reinforcement of synthetic geoways (e.g., roadways, runways), especially those fabricated from asphalt-based pavements. The improved softening point of the fibers allows their incorporation into the hot-mix pavement used to fabricate and repair such surfaces without degradation of the fibers by the elevated temperatures found in plants for these manufacture of hot-mix pavements. This invention also provides an improved process for making melts of such allows.
