    Abstract

    Several investigations have correlated various consistency measurements with stabilities of asphalt paving mixes. However, because of the experimental variations encountered and the time-consuming tests required to secure complete information, the quantitative relationship of viscosity to compressive strength for mixtures of various types has not been specifically established. In addition to generally reviewing the literature, this paper reports the results of a study of the relationship of absolute viscosity to compressive strength tests for several asphalts from different sources and at different temperatures. Most comparisons have been made on the basis of the viscosity of the asphalt recovered from the strength-test specimen.
