. The effect of asphalt and wax emulsions on moisture changes in slash. Prediction curves were calculated from sample weighings on rainless days to show the effect of the coatings on drying rate without rain. Curves of these relationships in the sun by mixing ratio for SS-1, primer, and sealant wax are shown in figures 7, 8, and 9. Table 2 gives the significance of the differences between predicted moisture without rain and actual moisture with rain as de- termined by the F Days Figure drying curves of green slash treated with SS-1, in the sun environment and without rain.

Table 2 gives the significance of the differences between predicted moisture without rain and actual moisture with rain as de- termined by the F Days Figure drying curves of green slash treated with SS-1, in the sun environment and without rain. The curve shapes in figures 7 to 9 are important. It will be noted that, generally, the curves depicting moisture content of treated samples versus time fall downward and to the right at a more constant rate than the curves showing moisture trends of untreated samples. This general result varies widely by mixing ratios, however. The curves of moisture trends of samples treated with SS-1 at 1:1 ratio, under sun conditions, most nearly approached a normal drying curve. This coating and ratio had the greatest effect on moisture loss or gain by green slash. The primer curves most nearly resembled those of their controls. Primer had the least effect on moisture loss or gain. 8.
