EVALUATION OF THE EFFECTS OF AGGREGATE ON RUTTING AND FATIGUE OF ASPHALT. FINAL REPORT

The objectives of this study were: 1) to determine the basic physical properties of aggregates from a representative sampling of aggregate quarries in Georgia and 2) to develop optimum asphalt mix designs for each aggregate class selected. Properties determined include aggregate shape, surface area, free mica, surface roughness, and petrographic analysis. The aggregate sources were classified into one of six classes having similar physical properties. Optimum mix designs were developed for base, surface, and binder mixes. These mixes were designed to be rut resistant and with improved fatigue life. The loaded wheel tester was used to determine rutting resistance. Base mixes with about 20% less rutting were developed.
