EFFECT OF MIX CONDITIONING ON PROPERTIES OF ASPHALTIC MIXTURES

The serviceability of asphalt pavements is controlled by many factors, such as expected load, mixture, and environmental variables. In order to provide satisfactory serviceability, an asphalt mixture must have several characteristics: stiffness, tensile strength, resistance to fatigue, permanent deformation, and resistance to water damage. Recently, water-induced damage of asphalt mixtures has caused serious distress, reduced performance, and increased maintenance for pavements in Oregon. The information from tests performed at Oregon State University concerning three projects built between 1978 and 1980 was used to determine relationships between asphalt concrete pavement performance as indicated by resilient modulus, indirect tensile strength, fatigue life, and mix level of compaction for both as-compacted and conditioned samples. It was found that the rate of water-induced damage of asphalt mixtures was strongly related to aggregate quality and air void content of the mixture--the higher the air void content and the poorer the aggregate, the larger the loss of strength.
