N2 - The presence of vesicles within basalt has a negative impact on its engineering properties. Thirty-four specimens of vesicular basalt were tested in unconfined compression to determine the engineering properties of peak strength (UCS) and deformation modulus. The low unit weight specimens showed a moderate increase in both UCS and modulus with increasing unit weight. The high unit weight specimens showed a rapid increase in properties with increasing unit weight. When the two groups were combined, the high unit weight specimens had the most influence on the form of the best-fit regression line. Peak strength was very well correlated with unit weight; the deformation modulus was not as well correlated. There was no discernible size effect observed between the two different core diameters; this may be due to the small size of the dataset, or the small difference in size between the two core diameters investigated. Further investigation is ongoing.
