Evaluation of Bituminous Mixes in Pavement Structures. Interim Report III. A Preliminary Study of the Use of the Stiffness Concept in Minimizing Low-Temperature Transverse Cracking
A review is presented of pertinent literature on characterizing the rheological properties of bitumen at low-temperatures, and relating these properties to the development of transverse cracks in flexible pavements. Various methods for direct and indirect determination of the 'stiffness modulus' of asphalt binders and mixtures are discussed. The stiffness moduli of thirty-one Oklahoma asphalt cement samples and a series of asphalt concrete mixtures were determined. Results were compared with limiting values suggested in the literature. A majority of the tested asphalt cements and mixtures exceeded the recommended critical stiffness values. The results indicated that the stiffness modulus approach can be applied to Oklahoma materials to identify suitable low-temperature characteristics that will mitigate transverse pavement cracking.
