DEVELOPMENT OF A RATIONAL MIX DESIGN METHOD FOR ASPHALT BASES AND CHARACTERISTICS OF ARKANSAS ASPHALT MIXTURES. FINAL REPORT ON TRANSPORTATION RESEARCH PROJECT NO. 66
The relationships between asphalt pavement performance parameters and physical characteristics of pavement cores and Marshall laboratory mixtures were investigated. Thirty-six pavement sites from all areas of Arkansas were cored and evaluated. Eight pavement sites had conventional granular bases, 17 sites had asphalt bases and 11 sites had portland cement concrete bases. All of the pavements were high-type asphalt concrete with 12 foot lanes, sealed shoulders and with good drainage. Their ages ranged from 0.5 to 23 years. Pavement field tests include: Dynaflect deflection, rut depth, crack classification, condition rating, and Mays Rideability rating. The cores were measured for layer thickness and sawed into layers. The core layers were tested for: resilient modulus, bulk specific gravity, maximum mixture specific gravity, Marshall stability and flow, asphalt content and aggregate gradation. Laboratory specimens having aggregate characteristics similiar to the pavement cores were molded with an AC-30 asphalt and likewise tested.
