THE CHEMICAL AND PHYSICAL PROPERTIES OF ASPHALT RUBBER MIXTURES. PART I. BASIC MATERIAL BEHAVIOR

The properties of asphalt-rubber mixtures composed of paving grade asphalt and ground automobile tire rubber are examined. The mechanism of swelling of the rubber in asphalt and asphalt-like materials is proposed and the effect of variables which affect the swelling is discussed. Experiments determining the swelling of tire rubber in selected oils are related to the swelling of tire rubber in asphalt. Several test methods are presented which measure the properties of the asphalt-rubber mixture. Data concerning the properties of a commercially available asphalt-rubber mixture and the effects of processing variables on these properties are presented. Techniques useful for the quality control of this material as well as suggestions for research into the theoretical aspects of the unique characteristics of this material are discussed.
