The quantity of asphalt residue in the emulsion used in an open graded cold mix will affect the quantity of emulsion needed to hold the aggregate skeleton/mixture together. With a lower asphalt residue, more asphalt emulsion is required to achieve the desired effect. Also, the more viscous the emulsion is, the better the mix should perform because open graded cold mixes
