Polyester Fibers for Asphaltic Pavement Reinforcement
Various methods of improving the tensile properties of bituminous concrete overlays have been studied over the years. When attempting to reduce cracks, some premium additive or product is usually added to the bituminous wearing course (PA ID-2) mix. The objective of the research project was to evaluate the benefits of including polyester fibers in bituminous concrete. Reduction of cracks and durability to pavement were examined on the basis of field performance. The research site is located in Schuylkill county on PA traffic route 61. The experimental sections were part of a three-mile resurfacing project. Two fiber concentrations were used in an ID-2 wearing course mix (0.125 percent and 0.25 percent of mix by weight). The fiber concentrations were very small, consequently, the fiber had a negligible effect on the skid resistance. Crack surveys showed that the addition of fibers also had little effect on reflective cracking.
