We present the spectra of 60 asteroids, including 47 V-types observed during the first phase of the Adler V-Type Asteroid (AVAST) Survey. SDSS photometry was used to select candidate V-type asteroids for follow up by nature of their very blue i - z color. 47 of the 61 observed candidates were positively classified as V-type asteroids, while an additional six show indications of a 0.9 {\mu}m feature consistent with V-type spectra, but not sufficient for formal classification. Four asteroids were found to be S-type, all of which had i - z values very near the adopted AVAST selection criteria of i - z \leq -0.2, including one candidate observed well outside the cut (at a mean i - z of -0.11). Three A-type asteroids were also identified. Six V-type asteroids were identified beyond the 3:1 mean motion resonance with Jupiter, and six more were found with low (< 5 deg) inclination, placing these asteroids outside of the normal dynamical range of classic Vestoids, and are suggestive of a non-Vesta origin for at least some of the population.
