Two discussions of a paper with the aforementioned title by Al-Sanad, Eid, and Ismael, published in this journal (Volume 121, Number 5, May 1995), are presented. In the first discussion, Mirza inquires about the minerological composition and angularity of oil-mixed desert sands. Discusser Mirza points out the nonlinear relationship between relative density and angle of friction that is apparent for oil mixed sand, in contrast to a linear relationship for uncontaminated sand. Also, the direct shear tests give friction angles greater than those derived from triaxial tests for the same relative density. In the second discussion, D'Andrea, O'Shaughnessy, and Pinheiro present results from their study of thermally treated, oil-contaminated aggregates in highway embankment construction and portland cement concrete. Discussions are followed by closure from the authors.
