The vegetation-based spraying method has been used as a revegetation measure for protecting slopes. However, after the method is applied to the fields, the collapse due to deteriorated bond performance of artificial slopes and defective vegetation growth bases prevent it from displaying its proper function. Therefore, research and application technologies for revegetation measures that can achieve both the reinforcement of slopes and the ecological restoration at the same time are necessary. Accordingly, in this study, fundamental research was conducted regarding the bond properties of slopes, according to the addition of additives based on bonding materials for improving bond performance.
