alkali salt e g potassium sulfate this corresponds to a ratio of about 20 asphalt emulsion e g ccs 1h and 80 magnesium chloride solution it should be noted that other asphalt emulsions could be substituted the following is a discussion of the present applicants 39 test of the present invention first a commercially available asphalt emulsion ccs 1h was diluted with water to make an emulsion containing about 35 asphalt emulsion and 65 water it should be noted that the amount of water was cut back in comparison to the prior art discussed above so when the magnesium chloride solution was added it would not thin it down too much the resulting asphalt emulsion was then heated to about 150 u00b0 f a magnesium chloride solution containing about 30 magnesium chloride and 70 water was heated to about 160 u00b0 f this allowed the asphalt emulsion to not clot in the blending process both products were then placed in a tank with a recirculation pump and blended for about two hours the product was then loaded into a distributor truck and applied to a test road surface the subgrade of the road surface was wet down with water and the.
