N2 - The presence of gas pockets called vesicles within basalt has a negative impact on the unconfined compressive strength (UCS) of the basalt, and also reduces the bulk specific gravity of the material. Previous research by Gates (2008) found that a comparison of the bulk specific gravity to the unconfined compressive strengths of vesicular basalts from three different sites demonstrated an exponential relationship. The objectives of this study were to prepare and test a set of 40 vesicular basalt cores in order to validate the equation proposed by Gates, or propose a new formula for our specimens. The results of the 10 laboratory tests preformed to date suggest that while the general trend of increasing UCS with increasing specific gravity is clear, for our specimens, Gates' formula underpredicts UCS. We propose an alternative exponential formula for our dataset, which will be validated upon testing of the remaining 30 specimens.
