EVALUATION OF RECYCLED RUBBER IN ASPHALT CONCRETE. FINAL REPORT

The purpose of this research was to evaluate the performance and the use of asphalt rubber binders and recycled rubber granules in asphalt pavement in the state of Iowa. This five year research project was initiated in June 1991 and it was incorporated into Muscatine County Construction Project US 61 from Muscatine to Blue Grass over an existing 10 in. (25.4 cm) by 24 ft (7.3 m) jointed rigid concrete pavement constructed in 1957. The research site consisted of four experimental sections (one section containing rubber chip, one section containing reacted asphalt rubber in both binder and surface, and two sections containing reacted asphalt rubber in surface) and four control sections. This report contains findings of the University of Northern Iowa research team covering selected responsibilities of the research project "Determination of the aging and changing of the conventional asphalt binder and asphalt-rubber binder". Based on the laboratory test, the inclusion of recycled crumb rubber into asphalt affects the ductility of modified binder at various temperatures.
